git://git.kernel.org/pub/scm/linux/kernel/git/viro/mmap.git/ master
Compared to the last posted variant:
* added Acked-by as posted on l-k
* fixed braino in do_brk() spotted by Hugh
* expanded comment on sun3 mmap2()
* removed useless check in score mmap2()
* added missing check in score mmap()
All changes had been discussed in the thread.
Shortlog:
Al Viro (20):
untangling do_mremap(), part 1
do_mremap() untangling, part 2
do_mremap() untangling, part 3
fix checks for expand-in-place mremap
fix the arch checks in MREMAP_FIXED case
fix pgoff in "have to relocate" case of mremap()
kill useless checks in sparc mremap variants
file ->get_unmapped_area() shouldn't duplicate work of get_unmapped_area()
arm: add arch_mmap_check(), get rid of sys_arm_mremap()
Kill ancient crap in s390 compat mmap
arch_mmap_check() on mn10300
Cut hugetlb case early for 32bit on ia64
Unify sys_mmap*
fix a struct file leak in do_mmap_pgoff()
Take arch_mmap_check() into get_unmapped_area()
switch do_brk() to get_unmapped_area()
sparc_brk() is not needed anymore
Get rid of open-coding in ia64_brk()
fix broken aliasing checks for MAP_FIXED on sparc32, mips, arm and sh
Add missing alignment check in arch/score sys_mmap()
