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" * emailed patches from Andrew Morton <akpm@linux-foundation.org: (193 commits) MAINTAINERS: update nomadik patterns MAINTAINERS: update usb/gadget patterns MAINTAINERS: update DMA BUFFER SHARING patterns kexec: verify the signature of signed PE bzImage kexec: support kexec/kdump on EFI systems kexec: support for kexec on panic using new system call kexec-bzImage64: support for loading bzImage using 64bit entry kexec: load and relocate purgatory at kernel load time purgatory: core purgatory functionality purgatory/sha256: provide implementation of sha256 in purgaotory context kexec: implementation of new syscall kexec_file_load kexec: new syscall kexec_file_load() declaration kexec: make kexec_segment user buffer pointer a union resource: provide new functions to walk through resources kexec: use common function for kimage_normal_alloc() and kimage_crash_alloc() kexec: move segment verification code in a separate function kexec: rename unusebale_pages to unusable_pages kernel: build bin2c based on config option CONFIG_BUILD_BIN2C bin2c: move bin2c in scripts/basic shm: wait for pins to be released when sealing ...
