• a5fc5eba4   x86: Convert BUG() to use unreachable() ... Browse Code »

  Use the new unreachable() macro instead of for(;;);. When
  allyesconfig is built with a GCC-4.5 snapshot on i686 the size of the
  text segment is reduced by 3987 bytes (from 6827019 to 6823032).

  Impact: reduce bug table size

  This allows reducing the bug table size by half. Perhaps there are
  other 64-bit architectures that could also make use of this.

• 1965aae3c   x86: Fix ASM_X86__ header guards ... Browse Code »

  Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:

  a. the double underscore is ugly and pointless.
  b. no leading underscore violates namespace constraints.
