Support for probing the Zicboz block size landed in Linux 6.6, which was
released a few weeks ago.  This provides the user-configured block size
when Zicboz is enabled.

1b173d0606 linux-user: xtensa: fix signal delivery in FDPIC
In FDPIC signal handlers are passed around as FD pointers. Actual code
address and GOT pointer must be fetched from memory by the QEMU code
that implements kernel signal delivery functionality. This change is
equivalent to the following kernel change:

4d84cc5887 linux-user/riscv: change default cpu to 'max'
Commit f57d5f8004 deprecated the 'any' CPU type but failed to change the
default CPU for linux-user. The result is that all linux-users
invocations that doesn't specify a different CPU started to show a
deprecation warning:

$ ./build/qemu-riscv64  ./foo-novect.out
qemu-riscv64: warning: The 'any' CPU is deprecated and will be removed in the future.

Change the default CPU for RISC-V linux-user from 'any' to 'max'.

Step in removing CC_OP: change the representation of CC_OP_FLAGS.
The 8 bits are distributed between 6 variables, which should make
it easy to keep up to date.

The code within cc_helper.c is quite ugly but is only temporary.

63c1b7de0a linux-user: Report AArch64 hwcap2 fields above bit 31
The AArch64 ELF hwcap2 field is 64 bits, but our get_elf_hwcap2()
works with uint32_t, so it accidentally fails to report any hwcaps
over bit 31.  Use uint64_t here.

The Arm hwcap2 is only 32 bits (because the ELF format makes these
fields be the size of "long" in the ABI), but since it shares the
prototype declaration for get_elf_hwcap2() it is easier to also
expand it to 64 bits.

The only hwcap fields we implement already that are affected by this
are the HBC and MOPS ones, neither of which were implemented in a
previous release, so this doesn't need backporting to older stable
branches.

38ee0a7dfb linux-user: Remap guest SIGABRT
Distinguish host SIGABRT from guest SIGABRT by mapping
the guest signal onto one of the host RT signals.

This prevents a cycle by which a host assertion failure
is caught and handled by host_signal_handler, queued for
the guest, and then we attempt to continue past the
host abort.  What happens next depends on the host libc,
but is neither good nor helpful.
