Subject: [POWERPC] Remove bogus comment about page_is_ram
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bcff4948c64e1af09e9a986e324626ee873d3a07;p=deliverable%2Flinux.git

[POWERPC] Remove bogus comment about page_is_ram

arch/powerpc/mm/mem.c states that page_is_ram is called by the code that
implements /dev/mem, which isn't true.  Remove the comment.
