Commit b65a9cfc ("Untangling ima mess, part 2: deal with counters")
moved the call of ima_file_check() from may_open() to do_filp_open() at a
point where the file descriptor is already opened.

This breaks the assumption made by IMA that file descriptors being closed
belong to files whose access was granted by ima_file_check(). The
consequence is that security.ima and security.evm are updated with good
values, regardless of the current appraisal status.

For example, if a file does not have security.ima, IMA will create it after
opening the file for writing, even if access is denied. Access to the file
will be allowed afterwards.

Avoid this issue by checking the appraisal status before updating
security.ima.

The Switchtec hardware has two types of memory windows: LUTs and Direct.
The first area in each BAR is for LUT windows and the remaining area is
for the direct region. The total number of LUT entries is set by a
configuration setting in hardware and they all must be the same
size. (This is fixed by switchtec_ntb to be 64K.)

switchtec_ntb enables the LUTs only for the first BAR and enables the
highest power of two possible. Seeing the LUTs are at the beginning of
the BAR, the direct memory window's alignment is affected. Therefore,
the maximum direct memory window size can not be greater than the number
of LUTs times 64K. The direct window in other BARs will not have this
restriction as the LUTs will not be enabled there. LUTs will only be
exposed through the NTB API if the use_lut_mw parameter is set.

Seeing the Switchtec hardware, by default, configures BARs to be 4G a
module parameter is given to limit the size of the advertised memory
windows. Higher layers tend to allocate the maximum BAR size and this
has a tendency to fail when they try to allocate 4GB of contiguous
memory.

Pretty straightforward implementation of doorbell registers.
The shift and mask were setup in an earlier patch and this just hooks
up the appropriate portion of the IDB register as the local doorbells
and the opposite portion of ODB as the peer doorbells. The DB mask is
protected by a spinlock to avoid concurrent read-modify-write accesses.

switchtec_ntb checks for a link by looking at the shared memory
window. If the magic number is correct and the other side indicates
their link is enabled then we take the link to be up.

Whenever we change our local link status we send a msg to the
other side to check whether it's up and change their status.

The current status is maintained in a flag so ntb_is_link_up
can return quickly.

We utilize Switchtec's link status notifier to also check link changes
when the switch notices a port changes state.

This includes setting up the requester ID table, and figuring out
which BAR corresponds to which memory window. (Seeing the switch
can be configured with any number of BARs.)

Also, seeing the device doesn't have hardware for scratchpads or
determining the link status, we create a shared memory window that has
these features. A magic number with a version component will be used
to determine if the other side's driver is actually up.

The shared memory window also informs the other side of the
size and count of the local memory windows.

With Switchtec hardware it's impossible to get the alignment parameters
for a peer's memory window until the peer's driver has configured its
windows. Strictly speaking, the link doesn't have to be up for this,
but the link being up is the only way the client can tell that
the other side has been configured.

This patch converts ntb_transport and ntb_perf to use this function after
the link goes up. This simplifies these clients slightly because they
no longer have to store the alignment parameters. It also tweaks
ntb_tool so that peer_mw_trans will print zero if it is run before
the link goes up.

Pull clk updates from Stephen Boyd:
 "We have two changes to the core framework this time around.

  The first being a large change that introduces runtime PM support to
  the clk framework. Now we properly call runtime PM operations on the
  device providing a clk when the clk is in use. This helps on SoCs
  where the clks provided by a device need something to be powered on
  before using the clks, like power domains or regulators. It also helps
  power those things down when clks aren't in use.

  The other core change is a devm API addition for clk providers so we
  can get rid of a bunch of clk driver remove functions that are just
  doing of_clk_del_provider().

  Outside of the core, we have the usual addition of clk drivers and
  smattering of non-critical fixes to existing drivers. The biggest diff
  is support for Mediatek MT2712 and MT7622 SoCs, but those patches
  really just add a bunch of data.

  By the way, we're trying something new here where we build the tree up
  with topic branches. We plan to work this into our workflow so that we
  don't step on each other's toes, and so the fixes branch can be merged
  on an as-needed basis.

  Summary:

  Core:
   - runtime PM support for clk providers
   - devm API for of_clk_add_hw_provider()

  New Drivers:
   - Mediatek MT2712 and MT7622
   - Renesas R-Car V3M SoC

  Updates:
   - runtime PM support for Samsung exynos5433/exynos4412 providers
   - removal of clkdev aliases on Samsung SoCs
   - convert clk-gpio to use gpio descriptors
   - various driver cleanups to match kernel coding style
   - Amlogic Video Processing Unit VPU and VAPB clks
   - sigma-delta modulation for Allwinner audio PLLs
   - Allwinner A83t Display clks
   - support for the second display unit clock on Renesas RZ/G1E
   - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
   - new clock ids for Rockchip rk3188 and rk3368 SoCs
   - various 'const' markings on clk_ops structures
   - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs"

Pull Kbuild updates from Masahiro Yamada:
 "One of the most remarkable improvements in this cycle is, Kbuild is
  now able to cache the result of shell commands. Some variables are
  expensive to compute, for example, $(call cc-option,...) invokes the
  compiler. It is not efficient to redo this computation every time,
  even when we are not actually building anything. Kbuild creates a
  hidden file ".cache.mk" that contains invoked shell commands and their
  results. The speed-up should be noticeable.

  Summary:

   - Fix arch build issues (hexagon, sh)

   - Clean up various Makefiles and scripts

   - Fix wrong usage of {CFLAGS,LDFLAGS}_MODULE in arch Makefiles

   - Cache variables that are expensive to compute

   - Improve cc-ldopton and ld-option for Clang

   - Optimize output directory creation"

There is no need to #define the license of the driver, just put it in
the MODULE_LICENSE() line directly as a text string.

This allows tools that check that the module license matches the source
code license to work properly, as there is no need to unwind the
unneeded dereference.
