Subject: [IA64] pgd_offset() constfication.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e4b05d4097eb6dab08bda86a72f6fdfdd9816395;p=linux-beck.git

[IA64] pgd_offset() constfication.

when compile 2.6.25-rc8-mm1, below warning happend.
because walk_page_range pass argument as "const struct mm*",
but pgd_offset() receive as "struct mm*".

  CC      mm/pagewalk.o
mm/pagewalk.c: In function 'walk_page_range':
mm/pagewalk.c:111: warning: passing argument 1 of 'pgd_offset' discards qualifiers from pointer target type
