Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.5 kernel cycle

  Core changes:

   - Expose pull up/down flags for the GPIO character device to
     userspace.

     After clear input from the RaspberryPi and Beagle communities, it
     has been established that prototyping, industrial automation and
     make communities strongly need this feature, and as we want people
     to use the character device, we have implemented the simple pull
     up/down interface for GPIO lines.

     This means we can specify that a (chip-specific) pull up/down
     resistor can be enabled, but does not offer fine-grained control
     such as cases where the resistance of the same pull resistor can be
     controlled (yet).

   - Introduce devm_fwnode_gpiod_get_index() and start to phase out the
     old symbol devm_fwnode_get_index_gpiod_from_child().

   - A bit of documentation clean-up work.

   - Introduce a define for GPIO line directions and deploy it in all
     GPIO drivers in the drivers/gpio directory.

   - Add a special callback to populate pin ranges when cooperating with
     the pin control subsystem and registering ranges as part of adding
     a gpiolib driver and a gpio_irq_chip driver at the same time. This
     is also deployed in the Intel Merrifield driver.

  New drivers:

   - RDA Micro GPIO controller.

   - XGS-iproc GPIO driver.

  Driver improvements:

   - Wake event and debounce support on the Tegra 186 driver.

   - Finalize the Aspeed SGPIO driver.

   - MPC8xxx uses a normal IRQ handler rather than a chained handler"

Pull clk updates from Stephen Boyd:
 "This merge window we have one small clk provider API in the core
  framework and then a bunch of driver updates and a handful of new
  drivers. In terms of diffstat the Qualcomm and Amlogic drivers are
  high up there because of all the clk data introcued by new drivers.
  The Nvidia Tegra driver had a lot of work done this cycle too to
  support suspend/resume and memory controllers. And the OMAP clk driver
  got proper clk and reset handling in place.

  Rounding out the patches are various updates to remove unused data,
  mark things static, correct incorrect data in drivers, etc. All the
  little things that improve drivers and maintain code health. I will
  point out that there's a patch in here for the GPIO clk driver, that
  almost nobody uses, which changes behavior and causes clk_set_rate()
  to try to change the GPIO gate clk's parent. Other than that things
  are fairly well SoC specific here.

  Core:
   - Add a clk provider API to get current parent index
   - Plug a memory leak in clk_unregister() path

  New Drivers:
   - CGU in Ingenix X1000
   - Bitmain BM1880 clks
   - Qualcomm MSM8998 GPU clk controllers
   - Qualcomm SC7180 GCC and RPMH clk controllers
   - Qualcomm QCS404 Q6SSTOP clk controllers
   - Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
   - Add support for the Renesas RZ/G2N (r8a774b1) SoC
   - Add Tegra20/30 External Memory Clock (EMC) support

  Updates:
   - Make gpio gate clks propagate rate setting up to parent
   - Prepare Armada 3700 for suspend to RAM by moving PCIe
     suspend/resume priority
   - Drop unused variables, enums, etc. in various clk drivers
   - Convert various drivers to use devm_platform_ioremap_resource()
   - Use struct_size() some more in various clk drivers
   - Improve Rockchip px30 clk tree
   - Add suspend/resume support to Tegra210 clk driver
   - Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
   - Allwinner DT exports and H6 clk tree fixes
   - Proper clk and reset handling for OMAP SoCs
   - Revamped TI divider clk to clamp max divider
   - Make 1443X/1416X PLL clock structure common for reusing among i.MX8
     SoCs
   - Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
   - Add VIDEO2_PLL clock for imx8mq
   - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
   - Add sm1 support in the Amlogic audio clock controller
   - Switch some clocks on R-Car Gen2/3 to .determine_rate()

   - Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3
   - Improve Renesas R-Car Gen3 SD clock handling

Pull sysctl system call removal from Eric Biederman:
 "As far as I can tell we have reached the point where no one enables
  the sysctl system call anymore. It still is enabled in a few
  defconfigs but they are mostly the rarely used one and in asking
  people about that it was more cut & paste enabled than anything else.

  This is single commit that just deletes code. Leaving just enough code
  so that the deprecated sysctl warning continues to be printed. If my
  analysis turns out to be wrong and someone actually cares it will be
  easy to revert this commit and have the system call again.

  There was one new xtensa defconfig in linux-next that enabled the
  system call this cycle and when asked about it the maintainer of the
  code replied that it was not enabled on purpose. As of today's
  linux-next tree that defconfig no longer enables the system call.

  What we saw in the review discussion was that if we go a step farther
  than my patch and mess with uapi headers there are pieces of code that
  won't compile, but nothing minds the system call actually disappearing
  from the kernel"

There's a bug in the new PAT code, the conversion of memtype_check_conflict()
is buggy:

   8d04a5f9: ("x86/mm/pat: Convert the PAT tree to a generic interval tree")

        dprintk("Overlap at 0x%Lx-0x%Lx\n", match->start, match->end);
        found_type = match->type;

-       node = rb_next(&match->rb);
-       while (node) {
-               match = rb_entry(node, struct memtype, rb);
-
-               if (match->start >= end) /* Checked all possible matches */
-                       goto success;
-
-               if (is_node_overlap(match, start, end) &&
-                   match->type != found_type) {
+       match = memtype_interval_iter_next(match, start, end);
+       while (match) {
+               if (match->type != found_type)
                        goto failure;
-               }

-               node = rb_next(&match->rb);
+               match = memtype_interval_iter_next(match, start, end);
        }

Note how the '>= end' condition to end the interval check, got converted
into:

+       match = memtype_interval_iter_next(match, start, end);

This is subtly off by one, because the interval trees interfaces require
closed interval parameters:

  include/linux/interval_tree_generic.h

 /*                                                                            \
  * Iterate over intervals intersecting [start;last]                           \
  *                                                                            \
  * Note that a node's interval intersects [start;last] iff:                   \
  *   Cond1: ITSTART(node) <= last                                             \
  * and                                                                        \
  *   Cond2: start <= ITLAST(node)                                             \
  */                                                                           \

  ...

                if (ITSTART(node) <= last) {            /* Cond1 */           \
                        if (start <= ITLAST(node))      /* Cond2 */           \
                                return node;    /* node is leftmost match */  \

[start;last] is a closed interval (note that '<= last' check) - while the
PAT 'end' parameter is 1 byte beyond the end of the range, because
ioremap() and the other mapping APIs usually use the [start,end)
half-open interval, derived from 'size'.

This is what ioremap() does for example:

        /*
         * Mappings have to be page-aligned
         */
        offset = phys_addr & ~PAGE_MASK;
        phys_addr &= PHYSICAL_PAGE_MASK;
        size = PAGE_ALIGN(last_addr+1) - phys_addr;

        retval = reserve_memtype(phys_addr, (u64)phys_addr + size,
                                                pcm, &new_pcm);

phys_addr+size will be on a page boundary, after the last byte of the
mapped interval.

So the correct parameter to use in the interval tree searches is not
'end' but 'end-1'.

This could have relevance if conflicting PAT ranges are exactly adjacent,
for example a future WC region is followed immediately by an already
mapped UC- region - in this case memtype_check_conflict() would
incorrectly deny the WC memtype region and downgrade the memtype to UC-.

BTW., rather annoyingly this downgrading is done silently in
memtype_check_insert():

int memtype_check_insert(struct memtype *new,
                         enum page_cache_mode *ret_type)
{
        int err = 0;

        err = memtype_check_conflict(new->start, new->end, new->type, ret_type);
        if (err)
                return err;

        if (ret_type)
                new->type = *ret_type;

        memtype_interval_insert(new, &memtype_rbroot);
        return 0;
}

So on such a conflict we'd just silently get UC- in *ret_type, and write
it into the new region, never the wiser ...

So assuming that the patch below fixes the primary bug the diagnostics
side of ioremap() cache attribute downgrades would be another thing to
fix.

Anyway, I checked all the interval-tree iterations, and most of them are
off by one - but I think the one related to memtype_check_conflict() is
the one causing this particular performance regression.

The only correct interval-tree searches were these two:

  arch/x86/mm/pat_interval.c:     match = memtype_interval_iter_first(&memtype_rbroot, 0, ULONG_MAX);
  arch/x86/mm/pat_interval.c:             match = memtype_interval_iter_next(match, 0, ULONG_MAX);

The ULONG_MAX was hiding the off-by-one in plain sight. :-)

Note that the bug was probably benign in the sense of implementing a too
strict cache attribute conflict policy and downgrading cache attributes,
so AFAICS the worst outcome of this bug would be a performance regression,
not any instabilities.

Tx doorbell is handled by txdb_tasklet and doesn't
have an associated IRQ.

Anyhow, imx_mu_shutdown ignores this and tries to
free an IRQ that wasn't requested for Tx DB resulting
in the following warning:

 "Audit is back for v5.5, albeit with only two patches:

   - Allow for the auditing of suspicious O_CREAT usage via the new
     AUDIT_ANOM_CREAT record.

   - Remove a redundant if-conditional check found during code analysis.
     It's a minor change, but when the pull request is only two patches
     long, you need filler in the pull request email"

Pull selinux updates from Paul Moore:
 "Only three SELinux patches for v5.5:

   - Remove the size limit on SELinux policies, the limitation was a
     lingering vestige and no longer necessary.

   - Allow file labeling before the policy is loaded. This should ease
     some of the burden when the policy is initially loaded (no need to
     relabel files), but it should also help enable some new system
     concepts which dynamically create the root filesystem in the
     initrd.

   - Add support for the "greatest lower bound" policy construct which
     is defined as the intersection of the MLS range of two SELinux
     labels"

Pull kgdb updates from Daniel Thompson:
 "The major change here is the work from Douglas Anderson that reworks
  the way kdb stack traces are handled on SMP systems. The effect is to
  allow all CPUs to issue their stack trace which reduced the need for
  architecture specific code to support stack tracing.

  Also included are general of clean ups from Doug and myself:

   - Remove some unused variables or arguments.

   - Tidy up the kdb escape handling code and fix a couple of odd corner
     cases.

   - Better ignore escape characters that do not form part of an escape
     sequence. This mostly benefits vi users since they are most likely
     to press escape as a nervous habit but it won't harm anyone else"

* tag 'kgdb-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux:
  kdb: Tweak escape handling for vi users
  kdb: Improve handling of characters from different input sources
