[merged] sparse-can-do-constant-folding-of-__builtin_bswap.patch removed from -mm tree

[akpm]

The patch titled
     Subject: include/linux/compiler-gcc.h: sparse can do constant folding of __builtin_bswap*()
has been removed from the -mm tree.  Its filename was
     sparse-can-do-constant-folding-of-__builtin_bswap.patch

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

From: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>
Subject: include/linux/compiler-gcc.h: sparse can do constant folding of __builtin_bswap*()

Sparse can do constant folding of __builtin_bswap*() since 2017.  Also, a
much recent version of Sparse is needed anyway, see commit 6ec4476ac825
("Raise gcc version requirement to 4.9").

So, remove the comment about sparse not being yet able to constant fold
__builtin_bswap*() and remove the corresponding test of __CHECKER__.
