The patch titled
Subject: include/linux/compiler-gcc.h: hide assume_aligned attribute from sparse
has been removed from the -mm tree. Its filename was

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: include/linux/compiler-gcc.h: hide assume_aligned attribute from sparse
The patch "slab.h: sprinkle __assume_aligned attributes" causes *tons* of
whinges if you do 'make C=2' with sparse 0.5.0:
CHECK drivers/media/usb/pwc/pwc-if.c
include/linux/slab.h:307:43: error: attribute '__assume_aligned__': unknown attribute
include/linux/slab.h:308:58: error: attribute '__assume_aligned__': unknown attribute
include/linux/slab.h:337:73: error: attribute '__assume_aligned__': unknown attribute
include/linux/slab.h:375:74: error: attribute '__assume_aligned__': unknown attribute
include/linux/slab.h:378:80: error: attribute '__assume_aligned__': unknown attribute
sparse apparently pretends to be gcc >= 4.9, yet isn't prepared to handle
all the function attributes supported by those gccs and complains loudly.
So hide the definition of __assume_aligned from it (so that the generic
one in compiler.h gets used).
