    aout: suppress A.OUT library support if !CONFIG_ARCH_SUPPORTS_AOUT · 7fa30315

    Suppress A.OUT library support if CONFIG_ARCH_SUPPORTS_AOUT is not set.
    Not all architectures support the A.OUT binfmt, so the ELF binfmt should not
    be permitted to go looking for A.OUT libraries to load in such a case.  Not
    only that, but under such conditions A.OUT core dumps are not produced either.
    To make this work, this patch also does the following:
     (1) Makes the existence of the contents of linux/a.out.h contingent on
     (2) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT
         core dumping code.
     (3) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline.  This
         is then included only where needed.  This means that this bit of arch
         code will be stored in the appropriate A.OUT binfmt module rather than
         the core kernel.
     (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not
         needed) and FRV.
    This patch depends on the previous patch to move STACK_TOP[_MAX] out of
    asm/a.out.h and into asm/processor.h as they're required whether or not A.OUT
    format is available.
