Subject: thp: special pmd_trans_* functions
X-Git-Tag: v2.6.38-rc1~156
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5f6e8da70a289d403975907371ce5738c726ad3f;p=pandora-kernel.git

thp: special pmd_trans_* functions

These returns 0 at compile time when the config option is disabled, to
allow gcc to eliminate the transparent hugepage function calls at compile
time without additional #ifdefs (only the export of those functions have
to be visible to gcc but they won't be required at link time and
huge_memory.o can be not built at all).

_PAGE_BIT_UNUSED1 is never used for pmd, only on pte.
