ARM: 9178/1: fix unmet dependency on BITREVERSE for HAVE_ARCH_BITREVERSE
Resending this to properly add it to the patch tracker - thanks for letting me know, Arnd :) When ARM is enabled, and BITREVERSE is disabled, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for HAVE_ARCH_BITREVERSE Depends on [n]: BITREVERSE [=n] Selected by [y]: - ARM [=y] && (CPU_32v7M [=n] || CPU_32v7 [=y]) && !CPU_32v6 [=n] This is because ARM selects HAVE_ARCH_BITREVERSE without selecting BITREVERSE, despite HAVE_ARCH_BITREVERSE depending on BITREVERSE. This unmet dependency bug was found by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution.

This option enables the use of hardware bit-reversal instructions on
architectures which support such operations.
