Objtool noinstr support and retpoline fixes

noinstr-kcsan-2020-05015

KCSAN atomics and READ_ONCE/WRITE_ONCE changes for isolating text poke

sunxi-clk-for-5.8-1

This time we only have a single minor rounding fix for the legacy
Allwinner clock support.

sunxi-dt-for-5.8-1

Our usual number of patches to improve the Allwinner Device Tree
support, including:
  - Support for the IOMMU on the H6
  - Support for cpufreq / thermal throttling on the H6
  - Support for the mailbox on the A64, A83t, H3, H5 and H6
  - New boards: A20-OLinuXino-LIME-eMMC

sunxi-fixes-for-5.7-1

Two fixes for the Allwinner SoCs, one to remove some inexistant sound card on
the A64, and one to fix the audio codec regulator on the pinetab.

sunxi-config-for-5.8-1

Two patches to enable the new cpufreq support on the H6 for the arm64
defconfig to enable the audio codec in sunxi_defconfig.

xfs-5.8-merge-4

New code for 5.8:
- Various cleanups to remove dead code, unnecessary conditionals,
  asserts, etc.
- Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
  redundantly.
- Tighten up our dmesg logging to ensure that everything is prefixed
  with 'XFS' for easier grepping.
- Kill a bunch of typedefs.
- Refactor the deferred ops code to reduce indirect function calls.
- Increase type-safety with the deferred ops code.
- Make the DAX mount options a tri-state.
- Fix some error handling problems in the inode flush code and clean up
  other inode flush warts.
- Refactor log recovery so that eac hlog item recovery functions now live
  with the other log item processing code.
- Fix some SPDX forms.

pm-5.7-rc6

Power management fix for 5.7-rc6

Prevent the suspend-to-idle internal loop from busy spinning after
a spurious ACPI SCI wakeup in some cases.

v5.6.13

This is the 5.6.13 stable release

v5.4.41

This is the 5.4.41 stable release

v4.19.123

This is the 4.19.123 stable release

du-next-20200514

R-Car Display Unit & related changes:

- DT bindings conversion to YAML
- Planes zpos sanity check and fix
- MAINTAINERS entry for LVDS panel driver

vfs-5.8-merge-2

(More) new code for 5.8:
- Introduce DONTCACHE flags for dentries and inodes.  This hint will
  cause the VFS to drop the associated objects immediately after the
  last put, so that we can change the file access mode (DAX or page
  cache) on the fly.

4.9.218-15

4.4.143-49-rockchip

v5.7-rc5

Linux 5.7-rc5

xfs-5.8-merge-3

- Various cleanups to remove dead code, unnecessary conditionals,
  asserts, etc.
- Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
  redundantly.
- Tighten up our dmesg logging to ensure that everything is prefixed
  with 'XFS' for easier grepping.
- Kill a bunch of typedefs.
- Refactor the deferred ops code to reduce indirect function calls.
- Increase type-safety with the deferred ops code.
- Make the DAX mount options a tri-state.

  other inode flush warts.
- Refactor log recovery so that eac hlog item recovery functions now live
  with the other log item processing code.

x86-urgent-2020-05-10

A set of fixes for x86:

 - Ensure that direct mapping alias is always flushed when changing page
   attributes. The optimization for small ranges failed to do so when
   the virtual address was in the vmalloc or module space.

 - Unbreak the trace event registration for syscalls without arguments
   caused by the refactoring of the SYSCALL_DEFINE0() macro.

 - Move the printk in the TSC deadline timer code to a place where it is
   guaranteed to only be called once during boot and cannot be rearmed by
   clearing warn_once after boot. If it's invoked post boot then lockdep
   rightfully complains about a potential deadlock as the calling context
   is different.

 - A series of fixes for objtool and the ORC unwinder addressing variety
   of small issues:

     Stack offset tracking for indirect CFAs in objtool ignored subsequent
     pushs and pops

     Repair the unwind hints in the register clearing entry ASM code

     Make the unwinding in the low level exit to usermode code stop after
     switching to the trampoline stack. The unwind hint is not longer valid
     and the ORC unwinder emits a warning as it can't find the registers
     anymore.

     Fix the unwind hints in switch_to_asm() and rewind_stack_do_exit()
     which caused objtool to generate bogus ORC data.

     Prevent unwinder warnings when dumping the stack of a non-current
     task as there is no way to be sure about the validity because the
     dumped stack can be a moving target.

     Make the ORC unwinder behave the same way as the frame pointer
     unwinder when dumping an inactive tasks stack and do not skip the
     first frame.

     Prevent ORC unwinding before ORC data has been initialized

     Immediately terminate unwinding when a unknown ORC entry type is
     found.

     Prevent premature stop of the unwinder caused by IRET frames.

     Fix another infinite loop in objtool caused by a negative offset which
     was not catched.

     Address a few build warnings in the ORC unwinder and add missing
     static/ro_after_init annotations

objtool-urgent-2020-05-10

A single fix for objtool to prevent an infinite loop in the jump table
search which can be triggered when building the kernel with
-ffunction-sections.

locking-urgent-2020-05-10

A single fix for the fallout of the recent futex uacess rework.

With those changes GCC9 fails to analyze arch_futex_atomic_op_inuser()
correctly and emits a 'maybe unitialized' warning. While we usually ignore
compiler stupidity the conditional store is pointless anyway because the
correct case has to store. For the fault case the extra store does no harm.
