Hmm, lets see ...

Ah, I see: mips:allmodconfig now fails to build in -next for a different
reason.

Error log:
In file included from <command-line>:
arch/mips/mm/init.c: In function 'mem_init':
include/linux/compiler_types.h:319:38: error: call to '__compiletime_assert_331'
	declared with attribute error: BUILD_BUG_ON failed: IS_ENABLED(CONFIG_32BIT) && (_PFN_SHIFT > PAGE_SHIFT)

I'll send a separate report on that (if it wasn't reported before).

Anyway, any reason for not applying this fix to mainline, ie why the
mips:allmodconfig build failure was not fixed in v5.9 ?
