Subject: percpu: use the right flag for get_vm_area()
X-Git-Tag: v2.6.31-rc7~15^2
X-Git-Url: http://git.cascardo.info/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=142d44b0dd6741a64a7bdbe029110e7c1dcf1d23

percpu: use the right flag for get_vm_area()

get_vm_area() only accepts VM_* flags, not GFP_*.

And according to the doc of get_vm_area(), here should be
VM_ALLOC.
