On kernels without CONFIG_MMU, we get a link error for the siw driver:
drivers/infiniband/sw/siw/siw_mem.o: In function `siw_umem_get':
siw_mem.c:(.text+0x4c8): undefined reference to `can_do_mlock'
This is probably not the only driver that needs the function and could
otherwise build correctly without CONFIG_MMU, so add a dummy variant that
always returns false.

With the original commit applied, z3fold_zpool_destroy() may get blocked
on wait_event() for indefinite time. Revert this commit for the time
being to get rid of this problem since the issue the original commit
addresses is less severe.

If userspace reads the buffer via blockdev while mounting,
sb_getblk()+modify can race with buffer read via blockdev.
For example,
FS userspace
bh = sb_getblk()
modify bh->b_data
read
ll_rw_block(bh)
fill bh->b_data by on-disk data
/* lost modified data by FS */
set_buffer_uptodate(bh)
set_buffer_uptodate(bh)
Userspace should not use the blockdev while mounting though, the udev
seems to be already doing this. Although I think the udev should try to
avoid this, workaround the race by small overhead.

Pull SafeSetID fix from Micah Morton:
"Jann Horn sent some patches to fix some bugs in SafeSetID for 5.3.
After he had done his testing there were a couple small code tweaks
that went in and caused this bug.
From what I can see SafeSetID is broken in 5.3 and crashes the kernel
every time during initialization if you try to use it. I came across
this bug when backporting Jann's changes for 5.3 to older kernels
(4.14 and 4.19). I've tested on a Chrome OS device with those kernels
and verified that this change fixes things.
It doesn't seem super useful to have this bake in linux-next, since it
is completely broken in 5.3 and nobody noticed"

Pull selinux updates from Paul Moore:
- Add LSM hooks, and SELinux access control hooks, for dnotify,
fanotify, and inotify watches. This has been discussed with both the
LSM and fs/notify folks and everybody is good with these new hooks.
- The LSM stacking changes missed a few calls to current_security() in
the SELinux code; we fix those and remove current_security() for
good.
- Improve our network object labeling cache so that we always return
the object's label, even when under memory pressure. Previously we
would return an error if we couldn't allocate a new cache entry, now
we always return the label even if we can't create a new cache entry
for it.
- Convert the sidtab atomic_t counter to a normal u32 with
READ/WRITE_ONCE() and memory barrier protection.
- A few patches to policydb.c to clean things up (remove forward
declarations, long lines, bad variable names, etc)

Make sure that bsg_queue_rq() calls put_device() if an error is

Currently we just -EINVAL a read or write to an fd that isn't backed
by ->read_iter() or ->write_iter(). But we can handle them just fine,
as long as we punt fo async context first.
Implement a simple loop function for doing ->read() or ->write()
instead, and ensure we call it appropriately.

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:

crypto: inside-secure - Fix unused variable warning when CONFIG_PCI=n
crypto: talitos - fix missing break in switch statement
Changing the switch() statement to symbolic constants made the compiler
(at least clang-9, did not check gcc) notice that there is one enum value
that is not handled here:
block/t10-pi.c:62:11: error: enumeration value 'T10_PI_TYPE0_PROTECTION'
not handled in switch [-Werror,-Wswitch]
Add a BUG_ON statement if we ever get to t10_pi_verify function with
TYPE0 and replace the switch() statement with if/else clause for the
valid types.
