David Woodhouse 5fbbc25a99 x86, boot: Fix word-size assumptions in has_eflag() inline asm ... Commit dd78b97367 ("x86, boot: Move CPU flags out of cpucheck") introduced ambiguous inline asm in the has_eflag() function. In 16-bit mode want the instruction to be 'pushfl', but we just say 'pushf' and hope the compiler does what we wanted. When building with 'clang -m16', it won't, because clang doesn't use the horrid '.code16gcc' hack that even 'gcc -m16' uses internally. Say what we mean and don't make the compiler make assumptions. [ hpa: ideally we would be able to use the gcc %zN construct here, but that is broken for 64-bit integers in gcc < 4.5. The code with plain "pushf/popf" is fine for 32- or 64-bit mode, but not for 16-bit mode; in 16-bit mode those are 16-bit instructions in .code16 mode, and 32-bit instructions in .code16gcc mode. ] Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Link: http://lkml.kernel.org/r/1391079628.26079.82.camel@shinybook.infradead.org Signed-off-by: H.
