Merge branch 'remove-h8300' of git://git.infradead.org/users/hch/misc into asm-generic
* 'remove-h8300' of git://git.infradead.org/users/hch/misc: remove the h8300 architecture This is clearly the least actively maintained architecture we have at the moment, and probably the least useful. It is now the only one that does not support MMUs at all, and most of the boards only support 4MB of RAM, out of which the defconfig kernel needs more than half just for .text/.data. Guenter Roeck did the original patch to remove the architecture in 2013 after it had already been obsolete for a while, and Yoshinori Sato brought it back in a much more modern form in 2015. Looking at the git history since the reinstantiation, it's clear that almost all commits in the tree are build fixes or cross-architecture cleanups: $ git log --no-merges --format=%an v4.5.. arch/h8300/ | sort | uniq -c | sort -rn | head -n 12 25 Masahiro Yamada 18 Christoph Hellwig 14 Mike Rapoport 9 Arnd Bergmann 8 Mark Rutland 7 Peter Zijlstra 6 Kees Cook 6 Ingo Molnar 6 Al Viro 5 Randy Dunlap 4 Yury Norov Signed-off-by: Arnd Bergmann <arnd@arndb.de>
