c19940db0f target/ppc: created ppc_{store,get}_vscr for generic vscr usage
Some functions unrelated to TCG use helper_m{t,f}vscr, so generic versions
of those functions were added to cpu.c, in preparation for compilation
without TCG

3e770bf7a9 target/ppc: isolated cpu init from translation logic
finished isolation of CPU initialization logic from
translation logic. CPU initialization now only has common code
and may or may not call accelerator-specific code, as the
build options require.

a829cec3a3 target/ppc: turned SPR R/W callbacks not static
To be able to compile translate_init.c.inc as a standalone file,
we have to make the callbacks accessible outside of translate.c;
This patch does exactly that

03282a3ab8 hw/ppc: moved has_spr to cpu.h
Moved has_spr to cpu.h as ppc_has_spr and turned it into an inline function.

45998ffcb4 target/ppc: moved ppc_store_lpcr to misc_helper.c
Moved the function ppc_store from mmu-hash64.c to misc_helper.c and the
prototype from mmu-hash64.h to cpu.h as it is a more appropriate place,
but it will have to have its implementation moved to a new file as
misc_helper.c should not be compiled in a !TCG environment.

The hypercalls h_enter, h_remove, h_bulk_remove, h_protect, and h_read,
have been moved to spapr_softmmu.c with the functions they depend on. The
functions is_ram_address and push_sregs_to_kvm_pr are not static anymore
as functions on both spapr_hcall.c and spapr_softmmu.c depend on them.
The hypercalls h_resize_hpt_prepare and h_resize_hpt_commit have been
divided, the KVM part stayed in spapr_hcall.c while the softmmu part
was moved to spapr_softmmu.c

ab5add4c7b hw/ppc/spapr.c: Make sure the host supports the selected MMU mode
Starting with Linux kernel v5.12 we dropped support[1] in KVM for
hosts that can't have their threads running in different MMU modes
(POWER9 < DD2.2). In these hosts, KVM will no longer report the
KVM_CAP_PPC_MMU_HASH_V3 capability[2] when the host is running Radix.

For guests that support both MMU modes, the negotiation during CAS
will make sure it selects the correct one.

For guests that only support Hash, such as P8 compat mode guests, the
following error is currently thrown:

support vector so that we error out as soon as we determine this guest
only supports Hash and the host doesn't.

5f779a3a26 linux-user/elfload: fix filling psinfo->pr_psargs
The current code dumps the memory between arg_start and arg_end,
which contains the argv pointers. This results in the

    Core was generated by `<garbage>`

message when opening the core file in GDB. This is because the code is
supposed to dump the actual arg strings. Fix by using arg_strings and
env_strings instead of arg_start and arg_end.

02d0de101c linux-user/alpha: Share code for TARGET_NR_sigaction
There's no longer a difference between the alpha code and
the generic code.

There is a type difference in target_old_sigaction.sa_flags,
which can be resolved with a very much smaller ifdef, which
allows us to finish sharing the target_sigaction definition.

e5360eabd2 hw/block/nvme: fix io-command set profile feature
Currently IO Command Set Profile feature is supported, but the feature
support flag not set. Further, this feature is changable. Fix that.

Additionally, remove filling default value of the CQE result with zero,
since it will fall back to the default case anyway.
