4ecd4d16a0 ppc: Rename ELF_MACHINE to be PPC specific
Rename ELF_MACHINE to be PPC specific. This is used as-is by the
various PPC bootloaders and is locally defined to ELF_MACHINE in linux
user in PPC specific ifdeffery.

This removes another architecture specific definition from the global
namespace (as desired by multi-arch).

b597c3f7da arm: Remove ELF_MACHINE from cpu.h
The only generic code relying on this is linux-user. Linux user
already has a lot of #ifdef TARGET_ customisation so instead, define
ELF_ARCH as either EM_ARM or EM_AARCH64 appropriately.

The armv7m bootloader can just pass EM_ARM directly, as that
is architecture specific code. Note that arm_boot already has its own
logic selecting an arm specific elf machine so this makes V7M more
consistent with arm_boot.

This removes another architecture specific definition from the global
namespace.

d276a604bf linux-user: elfload: Provide default for elf_check_arch
For many arch's this macro is defined as the predicatable behaviour
of checking the argument for eqaulity against ELF_ARCH. Provide a
default define as such, so only archs with special handling (usually
allowing multiple EM values) need to provide a def.

Arches that do any of:

1: provide this def exactly the same way as the new default
        (alpha, x86_64)
2: check against ELF_MACHINE while defining ELF_ARCH == ELF_MACHINE
        (arm, aarch64)
3: check against EM_FOO directly while defining ELF_ARCH == EM_FOO
        (unicore32, sparc32, ppc32, mips, openrisc, sh4, cris, m86k)

have their elf_check_arch removed as the default will provide the
correct behaviour.

4cbea59869 linux-user: remove --enable-guest-base/--disable-guest-base
All tcg host architectures now support the guest base and as
there is no real performance lost, it can be always enabled.

Anyway, guest base use can be disabled lively by setting guest
base to 0.

CONFIG_USE_GUEST_BASE is defined as (USE_GUEST_BASE && USER_ONLY),
it should have to be replaced by CONFIG_USER_ONLY in non CONFIG_USER_ONLY
parts, but as some other parts are using !CONFIG_SOFTMMU I have chosen to
use !CONFIG_SOFTMMU instead.

a70daba377 linux-user: Tell guest about big host page sizes
We tell the guest its page size via AUX vectors. The guest process then uses
this page size as information on which boundaries it can mmap() things.

However, if the host has a bigger page size granularity than the guest, it can
not fulfill these mmap() requests - which falls apart when MAP_FIXED is passed
to mmap.

So in that case, let the guest know that we're running on a bigger page size
granularity than the target would require.

This fixes running qemu-ppc (TARGET_PAGE_SIZE=4k) on a 64k page size ppc64 host
for me.

f46e9a0b99 target-ppc: Confirm That .bss Pages Are Valid
The existing code does a check to ensure that a .bss region is properly
mmap'd.  When additional mmap is required, the (guest) pages are also
validated.  However, this code has a bug: when host page size is larger
than target page size, it is possible for the .bss pages to already be
(host) mapped but the guest .bss pages may not be valid.

The check to mmap additional space is separated from the flagging of the
target (guest) pages, thus ensuring that both aspects are done properly.

0514ef2fbb target-i386: Replace cpuid_*features fields with a feature word array
This replaces the feature-bit fields on both X86CPU and x86_def_t
structs with an array.

With this, we will be able to simplify code that simply does the same
operation on all feature words (e.g. kvm_check_features_against_host(),
filter_features_for_kvm(), add_flagname_to_bitmaps(), CPU feature-bit
property lookup/registration, and the proposed "feature-words" property)

The following field replacements were made on X86CPU and x86_def_t:

  (cpuid_)features         -> features[FEAT_1_EDX]
  (cpuid_)ext_features     -> features[FEAT_1_ECX]
  (cpuid_)ext2_features    -> features[FEAT_8000_0001_EDX]
  (cpuid_)ext3_features    -> features[FEAT_8000_0001_ECX]
  (cpuid_)ext4_features    -> features[FEAT_C000_0001_EDX]
  (cpuid_)kvm_features     -> features[FEAT_KVM]
  (cpuid_)svm_features     -> features[FEAT_SVM]
  (cpuid_)7_0_ebx_features -> features[FEAT_7_0_EBX]

a29f998d04 elfload: fix size of registers for N32
Registers are 64-bit in size for the MIPS n32 ABI.  Define
target_elf_greg_t accordingly, and use the correct function
to do endian swaps.

ca98ac830f elfload: fix size of ABI-dependent fields in core dumps
Some fields in core dumps are 32-bit in 32-or-64 environments (ppc64abi32,
sparc32plus).  Use abi_long/ulong for those.

Also, the fields of target_elf_siginfo are ints.  Use tswap32 to convert them.
