9e59899f8c linux-user: Don't assume 0 is not a valid host timer_t value
For handling guest POSIX timers, we currently use an array
g_posix_timers[], whose entries are a host timer_t value, or 0 for
"this slot is unused".  When the guest calls the timer_create syscall
we look through the array for a slot containing 0, and use that for
the new timer.

This scheme assumes that host timer_t values can never be zero.  This
is unfortunately not a valid assumption -- for some host libc
versions, timer_t values are simply indexes starting at 0.  When
using this kind of host libc, the effect is that the first and second
timers end up sharing a slot, and so when the guest tries to operate
on the first timer it changes the second timer instead.

Rework the timer allocation code, so that:
 * the 'slot in use' indication uses a separate array from the
   host timer_t array
 * we grab the free slot atomically, to avoid races when multiple
   threads call timer_create simultaneously
 * releasing an allocated slot is abstracted out into a new
   free_host_timer_slot() function called in the correct places

This fixes:
 * problems on hosts where timer_t 0 is valid
 * the FIXME in next_free_host_timer() about locking
 * bugs in the error paths in timer_create where we forgot to release
   the slot we grabbed, or forgot to free the host timer

4c184e70ad linux-user/hppa: Allow PROT_GROWSUP and PROT_GROWSDOWN in mprotect()
The hppa platform uses an upwards-growing stack and required in Linux
kernels < 5.18 an executable stack for signal processing.  For that some
executables and libraries are marked to have an executable stack, for
which glibc uses the mprotect() syscall to mark the stack like this:
 mprotect(xfa000000,4096,PROT_EXEC|PROT_READ|PROT_WRITE|PROT_GROWSUP).

Currently qemu will return -TARGET_EINVAL for this syscall because of the
checks in validate_prot_to_pageflags(), which doesn't allow the
PROT_GROWSUP or PROT_GROWSDOWN flags and thus triggers this error in the
guest:
 error while loading shared libraries: libc.so.6: cannot enable executable stack as shared object requires: Invalid argument

Allow mprotect() to handle both flags and thus fix the guest.
The glibc tst-execstack testcase can be used to reproduce the issue.

0a3346b593 linux-user/hppa: Increase guest stack size to 80MB for hppa target
The hppa target requires a much bigger stack than many other targets,
and the Linux kernel allocates 80 MB by default for it.

This patch increases the guest stack for hppa to 80MB, and prevents
that this default stack size gets reduced by a lower stack limit on the
host.

Since the stack grows upwards on hppa, the stack_limit value marks the
upper boundary of the stack. Fix the output of /proc/self/maps (in the
guest) to show the [stack] marker on the correct memory area.

f43882052f linux-user/hppa: Drop stack guard page on hppa target
The stack-overflow check when building the "grep" debian package fails
on the debian hppa target. Reason is, that the guard page at the top
of the stack (which is added by qemu) prevents the fault handler in the
grep program to properly detect the stack overflow.

The Linux kernel on a physical machine doesn't install a guard page
either, so drop it and as such fix the build of "grep".

f93b76958a linux-user: Passthrough MADV_DONTNEED for certain file mappings
This is a follow-up for commit 892a4f6a75 ("linux-user: Add partial
support for MADV_DONTNEED"), which added passthrough for anonymous
mappings. File mappings can be handled in a similar manner.

In order to do that, mark pages, for which mmap() was passed through,
with PAGE_PASSTHROUGH, and then allow madvise() passthrough for these
pages. Drop the explicit PAGE_ANON check, since anonymous mappings are
expected to have PAGE_PASSTHROUGH anyway.

Add PAGE_PASSTHROUGH to PAGE_STICKY in order to keep it on mprotect().

d135f78140 linux-user: use 'max' instead of 'qemu32' / 'qemu64' by default
The 'qemu64' CPU model implements the least featureful x86_64 CPU that's
possible. Historically this hasn't been an issue since it was rare for
OS distros to build with a higher mandatory CPU baseline.

With RHEL-9, however, the entire distro is built for the x86_64-v2 ABI
baseline:

  https://developers.redhat.com/blog/2021/01/05/building-red-hat-enterprise-linux-9-for-the-x86-64-v2-microarchitecture-level

It is likely that other distros may take similar steps in the not too
distant future. For example, it has been suggested for Fedora on a
number of occasions.

This new baseline is not compatible with the qemu64 CPU model though.
While it is possible to pass a '-cpu xxx' flag to qemu-x86_64, the
usage of QEMU doesn't always allow for this. For example, the args
are typically controlled via binfmt rules that the user has no ability
to change. This impacts users who are trying to use podman on aarch64
platforms, to run containers with x86_64 content. There's no arg to
podman that can be used to change the qemu-x86_64 args, and a non-root
user of podman can not change binfmt rules without elevating privileges:

  https://github.com/containers/podman/issues/15456#issuecomment-1228210973

Changing to the 'max' CPU model gives 'qemu-x86_64' maximum
compatibility with binaries it is likely to encounter in the wild,
and not likely to have a significant downside for existing usage.

Most other architectures already use an 'any' CPU model, which is
often mapped to 'max' (or similar) already, rather than the oldest
possible CPU model.

For the sake of consistency the 'i386' architecture is also changed
from using 'qemu32' to 'max'.

c7546abfaa target/m68k: always call gen_exit_tb() after writes to SR
Any write to SR can change the security state so always call gen_exit_tb() when
this occurs. In particular MacOS makes use of andiw/oriw in a few places to
handle the switch between user and supervisor mode.

aece90d85d target/m68k: rename M68K_FEATURE_M68000 to M68K_FEATURE_M68K
The M68K_FEATURE_M68000 feature is misleading in that its name suggests the feature
is defined just for Motorola 68000 CPUs, whilst in fact it is defined for all
Motorola 680X0 CPUs.

In order to avoid confusion with the other M68K_FEATURE_M680X0 constants which
define the features available for specific Motorola CPU models, rename
M68K_FEATURE_M68000 to M68K_FEATURE_M68K and add comments to clarify its usage.

re-introduce our layered builds so bug out if we see FROM qemu/ in a
