The patch titled
Subject: tools: disable -Wno-type-limits
has been removed from the -mm tree. Its filename was
tools-disable-wno-type-limits.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Yury Norov <yury.norov@gmail.com>
Subject: tools: disable -Wno-type-limits
Patch series "lib/find_bit: fast path for small bitmaps", v6.
Bitmap operations are much simpler and faster in case of small bitmaps
which fit into a single word. In linux/bitmap.c we have a machinery that
allows compiler to replace actual function call with a few instructions if
bitmaps passed into the function are small and their size is known at
compile time.
find_*_bit() API lacks this functionality; but users will benefit from it
a lot. One important example is cpumask subsystem when NR_CPUS <=
BITS_PER_LONG.
This patch (of 12):
GENMASK(h, l) may be passed with unsigned types. In such case,
type-limits warning is generated for example in case of GENMASK(h, 0).
