So this series is looking pretty good to me, I've picked up #1-#3,
pending clarification on #4. I've stuck them into tip:x86/asm, because
they might interact with ongoing system call entry work.
While we are at it: CONFIG_IA32_EMULATION is a misnomer: there's
nothing 'emulated' there, it's full software and hardware support for
the 32-bit ABI. It's just an ugly (and somewhat confusing) replacement
for CONFIG_COMPAT that most other architectures are using.
So could we also get rid of CONFIG_IA32_EMULATION and change most of
its uses over to CONFIG_COMPAT et al? The only complication with that
might be that IA32_EMULATION kconfig switch hardcodes a few features
currently:
select BINFMT_ELF
select COMPAT_BINFMT_ELF
select HAVE_UID16
allowing the binfmt formats to be undefined should be OK; the uid16
dependency needs to be checked, whether it's safe to allow it to be
disabled.
Thanks,
Ingo
