Subject: lib/Kconfig: ZLIB_DEFLATE must select BITREVERSE
X-Git-Tag: Ubuntu-5.4-5.4.0-11.14~11454^2~1
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=1fd4e5c347bfcef6ae2c31f6a2abce00f6ecaa3f;p=mirror_ubuntu-focal-kernel.git

lib/Kconfig: ZLIB_DEFLATE must select BITREVERSE

lib/built-in.o: In function `__bitrev32':
deftree.c:(.text+0x1e799): undefined reference to `byte_rev_table'
deftree.c:(.text+0x1e7a0): undefined reference to `byte_rev_table'
deftree.c:(.text+0x1e7b4): undefined reference to `byte_rev_table'
deftree.c:(.text+0x1e7c1): undefined reference to `byte_rev_table'

Anything which uses bitrevX() has to select BITREVERSE, to grab
lib/bitrev.o.
