Commit bde5f6bc ("kmemleak: add scheduling point to
kmemleak_scan()") tries to rate-limit the frequency of cond_resched()
calls, but does it in a way which might incur an expensive division
operation in the inner loop.  Simplify this.

Add a variant of rbtree_replace_node() that maintains the leftmost cache
of struct rbtree_root_cached when replacing nodes within the rbtree.

As drm_mm is the only rb_replace_node() being used on an interval tree,
the mistake looks fairly self-contained.  Furthermore the only user of
drm_mm_replace_node() is its testsuite...

Pull RISC-V fixes from Palmer Dabbelt:
 "This contains three small fixes:

   - A fix to a typo in sys_riscv_flush_icache. This only effects error
     handling, but I think it's a small and obvious enough change that
     it's sane outside the merge window.

   - The addition of smp_mb__after_spinlock(), which was recently
     removed due to an incorrect comment. This is largly a comment
     change (as there's a big one now), and while it's necessary for
     complience with the RISC-V memory model the lack of this fence
     shouldn't manifest as a bug on current implementations.
     Nonetheless, it still seems saner to have the fence in 4.15.

   - The removal of some of the HVC_RISCV_SBI driver that snuck into the
     arch port. This is compile-time dead code in 4.15 (as the driver
     isn't in yet), and during the review process we found a better way
     to implement early printk on RISC-V. While this change doesn't do
     anything, it will make staging our HVC driver easier: without this
     change the HVC driver we hope to upstream won't build on 4.15
     (because the 4.15 arch code would reference a function that no
     longer exists).

  I don't think this is the last patch set we'll want for 4.15: I think
  I'll want to remove some of the first-level irqchip driver that snuck
  in as well, which will look a lot like the HVC patch here. This is
  pending some asm-generic cleanup I'm doing that I haven't quite gotten
  clean enough to send out yet, though, but hopefully it'll be ready by
  next week (and still OK for that late)"

Sending the switch state change twice within the same frame is invalid
evdev protocol and only works if the client handles keys immediately as
well. Processing events immediately is incorrect, it forces a fake
order of events that does not exist on the device.

Recent versions of libinput changed to only process the device state and
SYN_REPORT time, so now the key event is lost.

This is code that probably should never have made it into the kernel in

During the HVC_SBI_RISCV review process a better way of doing this was
suggested, but that means this code is defunct.  It's compile-time
disabled in 4.15 because the driver isn't in, so I think it's safe to
just remove this for now.

Assorted fixes for keyrings, ASN.1, X.509 and PKCS#7.

Historically, the XFS iomap_begin function only returned mappings for
exactly the range queried, i.e. it doesn't do XFS_BMAPI_ENTIRE lookups.
The current vfs iomap consumers are only set up to deal with trimmed
mappings.  xfs_xattr_iomap_begin does BMAPI_ENTIRE lookups, which is
inconsistent with the current iomap usage.  Remove the flag so that both
iomap_begin functions behave the same way.

FWIW this also fixes a behavioral regression in xattr FIEMAP that was
introduced in 4.8 wherein attr fork extents are no longer trimmed like
they used to be.

Commit 4675ff05

 ("kmemcheck: rip it out") has removed the code but
for some reason SPDX header stayed in place.  This looks like a rebase
mistake in the mmotm tree or the merge mistake.  Let's drop those
leftovers as well.

Pull media fixes from Mauro Carvalho Chehab:

 "A series of fixes for the media subsytem:

   - The largest amount of fixes in this series is with regards to
     comments that aren't kernel-doc, but start with "/**".

     A new check added for 4.15 makes it to produce a *huge* amount of
     new warnings (I'm compiling here with W=1). Most of the patches in
     this series fix those.

     No code changes - just comment changes at the source files

   - rc: some fixed in order to better handle RC repetition codes

   - v4l-async: use the v4l2_dev from the root notifier when matching
     sub-devices

   - v4l2-fwnode: Check subdev count after checking port

   - ov 13858 and et8ek8: compilation fix with randconfigs

   - usbtv: a trivial new USB ID addition

   - dibusb-common: don't do DMA on stack on firmware load

   - imx274: Fix error handling, add MAINTAINERS entry

   - sir_ir: detect presence of port"
