percpu: fix how @gfp is interpreted by the percpu allocator
When @gfp is specified, the percpu allocator is interested in whether it contains all of GFP_KERNEL or not. If it does, the normal allocation path is taken; otherwise, the atomic allocation path. Unfortunately, pcpu_alloc() was incorrectly testing for whether @gfp contains any part of GFP_KERNEL. Fix it by testing "(gfp & GFP_KERNEL) != GFP_KERNEL" instead of "!(gfp & GFP_KERNEL)" to decide whether the allocation should be atomic or not. Signed-off-by: Tejun Heo <tj@kernel.org>
