Btw., a very (very!) small stylistic nit that caught my eyes, and I realize
that
you just moved code, but could you please improve these macros a bit and make
it
look like regular kernel code? I.e. something like:
#define efi_call_virt(f, args...) \
({ \
efi_status_t __s; \
unsigned long flags; \
\
arch_efi_call_virt_setup(); \
\
local_save_flags(flags); \
__s = arch_efi_call_virt(f, args); \
efi_call_virt_check_flags(flags, __stringify(f)); \
arch_efi_call_virt_teardown(); \
\
__s; \
})
This delineates the various blocks of code: variables, setup, the
saving/calling
block plus the return code.
(Assuming the EFI folks like the whole approach.)
Thanks,
