Kevin Cernekee 1665010757 MIPS: Trivial style cleanups in mmap.c 
Fix checkpatch warnings.  Rename arch_get_unmapped_area_foo() to
arch_get_unmapped_area_common().  Make indentations and spacing more
consistent.  Add <linux/compiler.h> for likely/unlikely.

Jian Peng d0be89f6c2 MIPS: topdown mmap support 
This patch introduced topdown mmap support in user process address
space allocation policy.

Recently, we ran some large applications that use mmap heavily and
lead to OOM due to inflexible mmap allocation policy on MIPS32.

Since most other major archs supported it for years, it is reasonable
to follow the trend and reduce the pain of porting applications.

Due to cache aliasing concern, arch_get_unmapped_area_topdown() and
other helper functions are implemented in arch/mips/kernel/syscall.c.

Ralf Baechle 6f6c3c33c0 MIPS: Move arch_get_unmapped_area and gang to new file. 
It never really belonged into syscall.c and it's about to become well more
complex.
