Merge branch 'work.elf-compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull ELF compat updates from Al Viro:
"Sanitizing ELF compat support, especially for triarch architectures:
- X32 handling cleaned up
- MIPS64 uses compat_binfmt_elf.c both for O32 and N32 now
- Kconfig side of things regularized
Eventually I hope to have compat_binfmt_elf.c killed, with both native
and compat built from fs/binfmt_elf.c, with -DELF_BITS={64,32} passed
by kbuild, but that's a separate story - not included here"
* 'work.elf-compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
get rid of COMPAT_ELF_EXEC_PAGESIZE
compat_binfmt_elf: don't bother with undef of ELF_ARCH
Kconfig: regularize selection of CONFIG_BINFMT_ELF
mips compat: switch to compat_binfmt_elf.c
mips: don't bother with ELF_CORE_EFLAGS
mips compat: don't bother with ELF_ET_DYN_BASE
mips: KVM_GUEST makes no sense for 64bit builds...
mips: kill unused definitions in binfmt_elf[on]32.c
mips binfmt_elf*32.c: use elfcore-compat.h
x32: make X32, !IA32_EMULATION setups able to execute x32 binaries
[amd64] clean PRSTATUS_SIZE/SET_PR_FPVALID up properly
elf_prstatus: collect the common part (everything before pr_reg) into a struct
binfmt_elf: partially sanitize PRSTATUS_SIZE and SET_PR_FPVALID
