Peter Maydell ad6919dc0a linux-user/elfload.c: Support ARM HWCAP2 flags
The ARM kernel has chosen to spill into the HWCAP2 ELF feature bit flags
early, even though it hasn't yet exhausted all 32 bits of the HWCAP word.
Add support for setting this in the same way we do for HWCAP.

Richard Henderson c9baa30f42 tcg-s390: Use qemu_getauxval in query_facilities
No need to set up a SIGILL signal handler for detection anymore.

Remove a ton of sanity checks that must be true, given that we're
requiring a 64-bit build (the note about 31-bit KVM is satisfied
by configuring with TCI).

monitor command.

Before patch:

Ekaterina Tumanova 9b4f38e182 s390: Implement dump-guest-memory support for target s390x
With this patch dump-guest-memory on s390 produces an ELF formatted,
crash-readable dump.
In order to implement this, the arch-specific part of dump-guest-memory
was added:
target-s390x/arch_dump.c contains the whole set of function for writing
Elf note sections of all types for s390x.
