linux-user: Add support for a group of 2038 safe syscalls

This patch implements functionality for following time64 syscalls:

*clock_getres_time64

This a year 2038 safe variant of syscall:

int clock_getres(clockid_t clockid, struct timespec *res)
--finding the resoultion of a specified clock--
man page: https://man7.org/linux/man-pages/man2/clock_getres.2.html

*timer_gettime64
*timer_settime64

These are year 2038 safe variants of syscalls:

int timer_settime(timer_t timerid, int flags,
const struct itimerspec *new_value,
struct itimerspec *old_value)
int timer_gettime(timer_t timerid, struct itimerspec *curr_value)
--arming/dissarming and fetching state of POSIX per-process timer--
man page: https://man7.org/linux/man-pages/man2/timer_settime.2.html

*timerfd_gettime64
*timerfd_settime64

These are year 2038 safe variants of syscalls:

int timerfd_settime(int fd, int flags,
const struct itimerspec *new_value,
struct itimerspec *old_value)
int timerfd_gettime(int fd, struct itimerspec *curr_value)
--timers that notify via file descriptor--
man page: https://man7.org/linux/man-pages/man2/timerfd_settime.2.html

Implementation notes:

Syscall 'clock_getres_time64' was implemented similarly to 'clock_getres()'.
The only difference was that for the conversion of 'struct timespec' from
host to target, function 'host_to_target_timespec64()' was used instead of
'host_to_target_timespec()'.

For other syscalls, new functions 'host_to_target_itimerspec64()' and
'target_to_host_itimerspec64()' were added to convert the value of the
'struct itimerspec' from host to target and vice versa. A new type
'struct target__kernel_itimerspec' was added in 'syscall_defs.h'. This
type was defined with fields which are of the already defined type
'struct target_timespec'. This new 'struct target__kernel_itimerspec'
type is used in these new converting functions. These new functions were
defined similarly to 'host_to_target_itimerspec()' and 'target_to_host_itimerspec()'
the only difference being that 'target_to_host_timespec64()' and
'host_to_target_timespec64()' were used.

firmware (and crypto) patches

- add the tls-cipher-suites object,
- add the ability to QOM objects to produce data consumable
by the fw_cfg device,
- let the tls-cipher-suites object implement the
FW_CFG_DATA_GENERATOR interface.

This is required by EDK2 'HTTPS Boot' feature of OVMF to tell
the guest which TLS ciphers it can use.

Merge tag 'patchew/20200219160953.13771-1-imammedo@redhat.com' of https://github.com/patchew-project/qemu into HEAD

This series removes ad hoc RAM allocation API (memory_region_allocate_system_memory)
and consolidates it around hostmem backend. It allows to

* resolve conflicts between global -mem-prealloc and hostmem's "policy" option,
fixing premature allocation before binding policy is applied

* simplify complicated memory allocation routines which had to deal with 2 ways
to allocate RAM.

* reuse hostmem backends of a choice for main RAM without adding extra CLI
options to duplicate hostmem features. A recent case was -mem-shared, to
enable vhost-user on targets that don't support hostmem backends [1] (ex: s390)

* move RAM allocation from individual boards into generic machine code and
provide them with prepared MemoryRegion.

* clean up deprecated NUMA features which were tied to the old API (see patches)
- "numa: remove deprecated -mem-path fallback to anonymous RAM"
- (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0 and newer machine types"
- (POSTPONED) "numa: remove deprecated implicit RAM distribution between nodes"

Introduce a new machine.memory-backend property and wrapper code that aliases
global -mem-path and -mem-alloc into automatically created hostmem backend
properties (provided memory-backend was not set explicitly given by user).
A bulk of trivial patches then follow to incrementally convert individual
boards to using machine.memory-backend provided MemoryRegion.

Board conversion typically involves:

* providing MachineClass::default_ram_size and MachineClass::default_ram_id
so generic code could create default backend if user didn't explicitly provide
memory-backend or -m options

* dropping memory_region_allocate_system_memory() call

* using convenience MachineState::ram MemoryRegion, which points to MemoryRegion
allocated by ram-memdev

On top of that for some boards:

* missing ram_size checks are added (typically it were boards with fixed ram size)

* ram_size fixups are replaced by checks and hard errors, forcing user to
provide correct "-m" values instead of ignoring it and continuing running.

After all boards are converted, the old API is removed and memory allocation
routines are cleaned up.

linux-user: Add support for selected alsa timer instructions using ioctls

This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_START - Start selected alsa timer

Starts the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be started. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.

SNDRV_TIMER_IOCTL_STOP - Stop selected alsa timer

Stops the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be stopped. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.

SNDRV_TIMER_IOCTL_CONTINUE - Continue selected alsa timer

Continues the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be continued. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.

SNDRV_TIMER_IOCTL_PAUSE - Pause selected alsa timer

Pauses the timer device that is selected. The third ioctl's argument is
ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT"
should be called first to select the timer that is to be paused. If no
timer is selected, the error EBADFD ("File descriptor in bad shape")
is returned.

Implementation notes:

Since all of the implemented ioctls have NULL as their third argument,
their implementation was straightforward.

linux-user: Add support for getting/setting selected alsa timer parameters using ioctls

This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_INFO - Getting information about selected timer

Read information about the selected timer. The information is returned in
the following structure:

struct snd_timer_info {
unsigned int flags; /* timer flags - SNDRV_TIMER_FLG_* */
int card; /* card number */
unsigned char id[64]; /* timer identificator */
unsigned char name[80]; /* timer name */
unsigned long reserved0; /* reserved for future use */
unsigned long resolution; /* average period resolution in ns */
unsigned char reserved[64]; /* reserved for future use */
};

A pointer to this structure should be passed as the third ioctl's argument.
Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which information is to be obtained. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.

SNDRV_TIMER_IOCTL_PARAMS - Setting parameters for selected timer

Sets parameters for the selected timer. The paramaters are set in the
following structure:

struct snd_timer_params {
unsigned int flags; /* flags - SNDRV_TIMER_PSFLG_* */
unsigned int ticks; /* requested resolution in ticks */
unsigned int queue_size; /* total size of queue (32-1024) */
unsigned int reserved0; /* reserved, was: failure locations */
unsigned int filter; /* event filter */
unsigned char reserved[60]; /* reserved */
};

A pointer to this structure should be passed as the third ioctl's argument.
Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which parameters are to be set. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.

SNDRV_TIMER_IOCTL_STATUS - Getting status of selected timer

Read status of the selected timer. The status of the timer is returned in
the following structure:

struct snd_timer_status {
struct timespec tstamp; /* Timestamp - last update */
unsigned int resolution; /* current period resolution in ns */
unsigned int lost; /* counter of master tick lost */
unsigned int overrun; /* count of read queue overruns */
unsigned int queue; /* used queue size */
unsigned char reserved[64]; /* reserved */
};

A pointer to this structure should be passed as the third ioctl's argument.
Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which status is to be obtained. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.

Implementation notes:

All ioctls in this patch have pointer to some kind of a structure
as their third argument. That is the reason why corresponding
definitions were added in 'linux-user/syscall_types.h'. Structure
'snd_timer_status' has field of type 'struct timespec' which is why
a corresponding definition of that structure was also added in
'linux-user/syscall_types.h'. All of these strucutures have some
fields that are of type 'unsigned long'. That is the reason why
separate target structures were defined in 'linux-user/syscall_defs.h'.
Structure 'struct timespec' already had a separate target definition
so that definition was used to define a target structure for
'snd_timer_status'. The rest of the implementation was straightforward.

linux-user: Add support for selecting alsa timer using ioctl

This patch implements functionality of following ioctl:

SNDRV_TIMER_IOCTL_SELECT - Selecting timer

Selects the timer which id is specified. The timer id is specified in the
following strcuture:

struct snd_timer_select {
struct snd_timer_id id; /* timer ID */
unsigned char reserved[32]; /* reserved */
};

A pointer to this structure should be passed as the third ioctl's argument.
Before calling the ioctl, the field "tid" should be initialized with the id
information for the timer which is to be selected. If there is no timer
device with the specified id, the error ENODEV ("No such device") is
returned.

Implementation notes:

Ioctl implemented in this patch has a pointer to a

linux-user: Add support for getting/setting specified alsa timer parameters using ioctls

This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_GINFO - Getting information about specified timer

Read information about the specified timer. The information about the
timer is returned in the following structure:

struct snd_timer_ginfo {
struct snd_timer_id tid; /* requested timer ID */
unsigned int flags; /* timer flags - SNDRV_TIMER_FLG_* */
int card; /* card number */

unsigned long resolution_min; /* minimal period resolution in ns */
unsigned long resolution_max; /* maximal period resolution in ns */
unsigned int clients; /* active timer clients */
unsigned char reserved[32]; /* reserved */
};

A pointer to this structure should be passed as the third ioctl's argument.
Before calling the ioctl, the field "tid" should be initialized with the id
information for the timer which information is to be obtained. After the
ioctl call, the rest of the structure fields are filled with values from
the timer device with the specified id. If there is no device with the
specified id, the error ENODEV ("No such device") is returned.

SNDRV_TIMER_IOCTL_GPARAMS - Setting precise period duration

Sets timer precise period duration numerator and denominator in seconds. The
period duration is set in the following structure:

struct snd_timer_gparams {
struct snd_timer_id tid; /* requested timer ID */
unsigned long period_num; /* period duration - numerator */
unsigned long period_den; /* period duration - denominator */
unsigned char reserved[32]; /* reserved */
};

A pointer to this structure should be passed as the third ioctl's argument.
Before calling the ioctl, the field "tid" should be initialized with the id
information for the timer which period duration is to be set. Also, the
fileds "period_num" and "period_den" should be filled with the period
duration numerator and denominator values that are to be set respectively.
If there is no device with the specified id, the error ENODEV ("No such
device") is returned.

SNDRV_TIMER_IOCTL_GSTATUS - Getting current period resolution

Read timer current period resolution in nanoseconds and period resolution
numerator and denominator in seconds. The period resolution information is
returned in the following structure:

struct snd_timer_gstatus {
struct snd_timer_id tid; /* requested timer ID */
unsigned long resolution; /* current period resolution in ns */
unsigned long resolution_num; /* period resolution - numerator */
unsigned long resolution_den; /* period resolution - denominator */
unsigned char reserved[32]; /* reserved for future use */
};

A pointer to this structure should be passed as the third ioctl's argument.

linux-user: Add support for getting alsa timer version and id

This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_PVERSION - Getting the sound timer version

linux-user: Add support for getting alsa timer version and id

This patch implements functionalities of following ioctls:

SNDRV_TIMER_IOCTL_PVERSION - Getting the sound timer version

Read the sound timer version. The third ioctl's argument is
a pointer to an int in which the specified timers version
is returned.

SNDRV_TIMER_IOCTL_NEXT_DEVICE - Getting id information about next timer

Read id information about the next timer device from the sound timer
device list. The id infomration is returned in the following structure:

struct snd_timer_id {
int dev_class; /* timer device class number */
int dev_sclass; /* slave device class number (unused) */
int card; /* card number */
int device; /* device number */
int subdevice; /* sub-device number */
};

The devices in the sound timer device list are arranged by the fields
of this structure respectively (first by dev_class number, then by
card number, ...). A pointer to this structure should be passed as
the third ioctl's argument. Before calling the ioctl, the parameters
of this structure should be initialized in relation to the next timer
device which information is to be obtained. For example, if a wanted
timer device has the device class number equal to or bigger then 2,
the field dev_class should be initialized to 2. After the ioctl call,
the structure fields are filled with values from the next device in
the sound timer device list. If there is no next device in the list,
the structure is filled with "zero" id values (in that case all
fields are filled with value -1).

Implementation notes:

The ioctl 'SNDRV_TIMER_IOCTL_NEXT_DEVICE' has a pointer to a
'struct snd_timer_id' as its third argument. That is the reason why
corresponding definition is added in 'linux-user/syscall_types.h'.
Since all elements of this structure are of type 'int', the rest of
the implementation was straightforward.

The line '#include <linux/rtc.h>' was added to recognize
preprocessor definitions for these ioctls. This needs to be
done only once in this series of commits. Also, the content
of this file (with respect to ioctl definitions) remained
unchanged for a long time, therefore there is no need to
worry about supporting older Linux kernel version.

RISC-V Patches for the 5.0 Soft Freeze, Part 1

This patch set contains a handful of collected fixes that I'd like to target
for the 5.0 soft freeze (I know that's a long way away, I just don't know what
else to call these):

* A fix for a memory leak initializing the sifive_u board.
* Fixes to privilege mode emulation related to interrupts and fstatus.

Notably absent is the H extension implementation. That's pretty much reviewed,
but not quite ready to go yet and I didn't want to hold back these important
fixes. This boots 32-bit and 64-bit Linux (buildroot this time, just for fun)
and passes "make check".
