Merge branch 'akpm' (second patchbomb from Andrew Morton)
Merge more incoming from Andrew Morton:
"Two new syscalls:
memfd_create in "shm: add memfd_create() syscall"
kexec_file_load in "kexec: implementation of new syscall kexec_file_load"
And:
- Most (all?) of the rest of MM
- Lots of the usual misc bits
- fs/autofs4
- drivers/rtc
- fs/nilfs
- procfs
- fork.c, exec.c
- more in lib/
- rapidio
- Janitorial work in filesystems: fs/ufs, fs/reiserfs, fs/adfs,
fs/cramfs, fs/romfs, fs/qnx6.
- initrd/initramfs work
- "file sealing" and the memfd_create() syscall, in tmpfs
- add pci_zalloc_consistent, use it in lots of places
- MAINTAINERS maintenance
- kexec feature work"
