Replace qemu_real_host_page variables with inlined functions

Replace the global variables with inlined helper functions. getpagesize() is very
likely annotated with a "const" function attribute (at least with glibc), and thus
optimization should apply even better.

This avoids the need for a constructor initialization too.

Merge remote-tracking branch 'remotes/cminyard/tags/for-qemu-6.1-2' into staging

Some qemu updates for IPMI and I2C

Move some ADC file to where they belong and move some sensors to a
sensor directory, since with new BMCs coming in lots of different
sensors should be coming in. Keep from cluttering things up.

Add support for I2C PMBus devices.

Replace the confusing and error-prone i2c_send_recv and i2c_transfer with
specific send and receive functions. Several errors have already been
made with these, avoid any new errors.

Fix the watchdog_expired field in the IPMI watchdog, it's not a bool,
it's a u8. After a vmstate transfer, the new value could be wrong.

ppc patch queue 2021-07-09

Here's a (probably) final pull request before the qemu-6.1 soft
freeze. Includes:
* Implementation of the new H_RPT_INVALIDATE hypercall
* Virtual Open Firmware for pSeries and pegasos2 machine types.
This is an experimental minimal Open Firmware implementation which
works by delegating nearly everything to qemu itself via a special
hypercall.
* A number of cleanups to the ppc soft MMU code
* Fix to handling of two-level radix mode translations for the
powernv machine type
* Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits.
This will allow more flexible handling of possible future CPU
Spectre-like flaws
* Correctly treat mtmsrd as an illegal instruction on BookE cpus
* Firmware update for the ppce500 machine type

Deprecate pmem=on with non-DAX capable backend file

It is not safe to pretend that emulated NVDIMM supports
persistence while backend actually failed to enable it
and used non-persistent mapping as fall back.
Instead of falling-back, QEMU should be more strict and
error out with clear message that it's not supported.
So if user asks for persistence (pmem=on), they should
store backing file on NVDIMM.

util/mmap-alloc: Support RAM_NORESERVE via MAP_NORESERVE under Linux

Let's support RAM_NORESERVE via MAP_NORESERVE on Linux. The flag has no
effect on most shared mappings - except for hugetlbfs and anonymous memory.

Linux man page:
"MAP_NORESERVE: Do not reserve swap space for this mapping. When swap
space is reserved, one has the guarantee that it is possible to modify
the mapping. When swap space is not reserved one might get SIGSEGV
upon a write if no physical memory is available. See also the discussion
of the file /proc/sys/vm/overcommit_memory in proc(5). In kernels before
2.6, this flag had effect only for private writable mappings."

Note that the "guarantee" part is wrong with memory overcommit in Linux.

Also, in Linux hugetlbfs is treated differently - we configure reservation
of huge pages from the pool, not reservation of swap space (huge pages
cannot be swapped).

The rough behavior is [1]:
a) !Hugetlbfs:

1) Without MAP_NORESERVE *or* with memory overcommit under Linux
disabled ("/proc/sys/vm/overcommit_memory == 2"), the following
accounting/reservation happens:
For a file backed map
SHARED or READ-only - 0 cost (the file is the map not swap)
PRIVATE WRITABLE - size of mapping per instance

For an anonymous or /dev/zero map
SHARED - size of mapping
PRIVATE READ-only - 0 cost (but of little use)
PRIVATE WRITABLE - size of mapping per instance

2) With MAP_NORESERVE, no accounting/reservation happens.

b) Hugetlbfs:

1) Without MAP_NORESERVE, huge pages are reserved.

2) With MAP_NORESERVE, no huge pages are reserved.

Note: With "/proc/sys/vm/overcommit_memory == 0", we were already able
to configure it for !hugetlbfs globally; this toggle now allows
configuring it more fine-grained, not for the whole system.

The target use case is virtio-mem, which dynamically exposes memory
inside a large, sparse memory area to the VM.

memory: Introduce RAM_NORESERVE and wire it up in qemu_ram_mmap()

Let's introduce RAM_NORESERVE, allowing mmap'ing with MAP_NORESERVE. The
new flag has the following semantics:

"
RAM is mmap-ed with MAP_NORESERVE. When set, reserving swap space (or huge
pages if applicable) is skipped: will bail out if not supported. When not
set, the OS will do the reservation, if supported for the memory type.
"

Allow passing it into:
- memory_region_init_ram_nomigrate()
- memory_region_init_resizeable_ram()
- memory_region_init_ram_from_file()

... and teach qemu_ram_mmap() and qemu_anon_ram_alloc() about the flag.
Bail out if the flag is not supported, which is the case right now for
both, POSIX and win32. We will add Linux support next and allow specifying
RAM_NORESERVE via memory backends.

The target use case is virtio-mem, which dynamically exposes memory
inside a large, sparse memory area to the VM.

util/mmap-alloc: Pass flags instead of separate bools to qemu_ram_mmap()

Let's pass flags instead of bools to prepare for passing other flags and
update the documentation of qemu_ram_mmap(). Introduce new QEMU_MAP_
flags that abstract the mmap() PROT_ and MAP_ flag handling and simplify
it.

We expose only flags that are currently supported by qemu_ram_mmap().
Maybe, we'll see qemu_mmap() in the future as well that can implement these
flags.

Note: We don't use MAP_ flags as some flags (e.g., MAP_SYNC) are only
defined for some systems and we want to always be able to identify
these flags reliably inside qemu_ram_mmap() -- for example, to properly
warn when some future flags are not available or effective on a system.
Also, this way we can simplify PROT_ handling as well.
