Pull char/misc driver fixes from Greg KH: "Here are some small char and misc driver fixes for 4.17-rc3 A variety of small things that have fallen out after 4.17-rc1 was out. Some vboxguest fixes for systems with lots of memory, amba bus fixes, some MAINTAINERS updates, uio_hv_generic driver fixes, and a few other minor things that resolve problems that people reported. The amba bus fixes took twice to get right, the first time I messed up applying the patches in the wrong order, hence the revert and later addition again with the correct fix, sorry about that. All of these have been in linux-next with no reported issues" * tag 'char-misc-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: ARM: amba: Fix race condition with driver_override ARM: amba: Make driver_override output consistent with other buses Revert "ARM: amba: Fix race condition with driver_override" ARM: amba: Don't read past the end of sysfs "driver_override" buffer ARM: amba: Fix race condition with driver_override virt: vbox: Log an error when we fail to get the host version virt: vbox: Use __get_free_pages instead of kmalloc for DMA32 memory virt: vbox: Add vbg_req_free() helper function virt: vbox: Move declarations of vboxguest private functions to private header slimbus: Fix out-of-bounds access in slim_slicesize() MAINTAINERS: add dri-devel&linaro-mm for Android ION fpga-manager: altera-ps-spi: preserve nCONFIG state MAINTAINERS: update my email address uio_hv_generic: fix subchannel ring mmap uio_hv_generic: use correct channel in isr uio_hv_generic: make ring buffer attribute for primary channel uio_hv_generic: set size of ring buffer attribute ANDROID: binder: prevent transactions into own process.

help
Direct Access (DAX) can be used on memory-backed block devices.
If the block device supports DAX and the filesystem supports DAX,
then you can avoid using the pagecache to buffer I/Os. Turning
on this option will compile in support for DAX; you will need to
mount the filesystem using the -o dax option.
If you do not have a block device that is capable of using this,
or if unsure, say N. Saying Y will increase the size of the kernel
by about 5kB.

This option enables the export operations for a filesystem to support
external block IO.
config FILE_LOCKING

help
This option enables standard file locking support, required
for filesystems like NFS and for the flock() system
call. Disabling this option saves about 11k.

help
This option enables files appropriately marked files on appropriely

To the best of my knowledge this is dead code that no one cares about.

bool "Tmpfs virtual memory file system support (former shm fs)"
depends on SHMEM
help
Tmpfs is a file system which keeps all files in virtual memory.
Everything in tmpfs is temporary in the sense that no files will be
created on your hard drive. The files live in memory and swap
space. If you unmount a tmpfs instance, everything stored therein is
lost.
See <file:Documentation/filesystems/tmpfs.txt> for details.
config TMPFS_POSIX_ACL

select TMPFS_XATTR
select FS_POSIX_ACL
help
POSIX Access Control Lists (ACLs) support additional access rights
for users and groups beyond the standard owner/group/world scheme,
and this option selects support for ACLs specifically for tmpfs
filesystems.
If you've selected TMPFS, it's possible that you'll also need
this option as there are a number of Linux distros that require
POSIX ACL support under /dev for certain features to work properly.
For example, some distros need this feature for ALSA-related /dev
files for sound to work properly. In short, if you're not sure,
say Y.
config TMPFS_XATTR
bool "Tmpfs extended attributes"
depends on TMPFS
default n
help
Extended attributes are name:value pairs associated with inodes by
the kernel or by users (see the attr(5) manual page for details).
Currently this enables support for the trusted.* and
security.* namespaces.
You need this for POSIX ACL support on tmpfs.
If unsure, say N.
