Subject: x86, paravirt: fix build error when thp is disabled
X-Git-Tag: v3.8-rc1~69
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c36e0501ee91d7616a188efbf9714b1fce150032;p=pandora-kernel.git

x86, paravirt: fix build error when thp is disabled

With CONFIG_PARAVIRT=y and CONFIG_TRANSPARENT_HUGEPAGE=n, the build breaks
because set_pmd_at() is undeclared:

  mm/memory.c: In function 'do_pmd_numa_page':
  mm/memory.c:3520: error: implicit declaration of function 'set_pmd_at'
  mm/mprotect.c: In function 'change_pmd_protnuma':
  mm/mprotect.c:120: error: implicit declaration of function 'set_pmd_at'

This is because paravirt defines set_pmd_at() only when
CONFIG_TRANSPARENT_HUGEPAGE=y and such a restriction is unneeded.  The
fix is to define it for all CONFIG_PARAVIRT configurations.
