The patch titled
Subject: ARM: avoid ARCH_MMAP_RND_BITS for NOMMU
has been removed from the -mm tree. Its filename was
arm-mm-support-arch_mmap_rnd_bits-fix.patch
This patch was dropped because it was folded into arm-mm-support-arch_mmap_rnd_bits.patch
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: ARM: avoid ARCH_MMAP_RND_BITS for NOMMU
ARM kernels with MMU disabled fail to build because of CONFIG_ARCH_MMAP_RND_BITS:
kernel/built-in.o:(.data+0x754): undefined reference to `mmap_rnd_bits'
kernel/built-in.o:(.data+0x76c): undefined reference to `mmap_rnd_bits_min'
kernel/built-in.o:(.data+0x770): undefined reference to `mmap_rnd_bits_max'
This changes the newly added line to only select this allow for
MMU-enabled kernels.
Fixes: 14570b3fd31a ("arm: mm: support ARCH_MMAP_RND_BITS")
