Peter Delevoryas 713911a107 ui/cocoa: Fix switched_to_fullscreen warning
I noticed this error while building QEMU on Mac OS X:

    [1040/1660] Compiling Objective-C object libcommon.fa.p/ui_cocoa.m.o
    ../ui/cocoa.m:803:17: warning: variable 'switched_to_fullscreen' set but not used [-Wunused-but-set-variable]
        static bool switched_to_fullscreen = false;
                    ^
    1 warning generated.

I think the behavior is fine if you remove "switched_to_fullscreen", I can
still switch in and out of mouse grabbed mode and fullscreen mode with this
change, and Command keycodes will only be passed to the guest if the mouse
is grabbed, which I think is the right behavior. I'm not sure why a static
piece of state was needed to handle that in the first place. Perhaps the
refactoring of the flags-state-change fixed that by toggling the Command
keycode on.

I tested this with an Ubuntu core image on macOS 12.4

    wget https://cdimage.ubuntu.com/ubuntu-core/18/stable/current/ubuntu-core-18-i386.img.xz
    xz -d ubuntu-core-18-i386.img.xz
    qemu-system-x86_64 -drive file=ubuntu-core-18.i386.img,format=raw

Philippe Mathieu-Daudé 7630156d34 configure: Restrict TCG to emulation
If we don't need to emulate any target, we certainly don't need TCG.

This should also help to compile again with
 ".../configure --enable-tools --disable-system --disable-user"
on systems that do not have a TCG backend.

Ilya Leoshkevich b0f650f047 accel/tcg: Fix unaligned stores to s390x low-address-protected lowcore
If low-address-protection is active, unaligned stores to non-protected
parts of lowcore lead to protection exceptions. The reason is that in
such cases tlb_fill() call in store_helper_unaligned() covers
[0, addr + size) range, which contains the protected portion of
lowcore. This range is too large.

The most straightforward fix would be to make sure we stay within the
original [addr, addr + size) range. However, if an unaligned access
affects a single page, we don't need to call tlb_fill() in
store_helper_unaligned() at all, since it would be identical to
the previous tlb_fill() call in store_helper(), and therefore a no-op.
If an unaligned access covers multiple pages, this situation does not
occur.

Therefore simply skip TLB handling in store_helper_unaligned() if we
are dealing with a single page.

Shaobo Song ba8924113c tcg: Fix returned type in alloc_code_gen_buffer_splitwx_memfd()
This fixes a bug in POSIX-compliant environments. Since we had allocated
a buffer named 'tcg-jit' with read-write access protections we need a int
type to combine these access flags and return it, whereas we had inexplicably
return a bool type. It may cause an unnecessary protection change in
tcg_region_init().

or records that are smaller than the header.  We were silently
allowing these cases to pass, dropping the record.
