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 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.

linux-user: Use `qemu_log' for strace

This change switches linux-user strace logging to use the newer `qemu_log`
logging subsystem rather than the older `gemu_log` (notice the "g")
logger. `qemu_log` has several advantages, namely that it allows logging
to a file, and provides a more unified interface for configuration
of logging (via the QEMU_LOG environment variable or options).

This change introduces a new log mask: `LOG_STRACE` which is used for
logging of user-mode strace messages.

linux-user: Use `qemu_log' for non-strace logging

Since most calls to `gemu_log` are actually logging unimplemented features,
this change replaces most non-strace calls to `gemu_log` with calls to
`qemu_log_mask(LOG_UNIMP, ...)`. This allows the user to easily log to
a file, and to mask out these log messages if they desire.

Note: This change is slightly backwards incompatible, since now these
"unimplemented" log messages will not be logged by default.
