Pull device mapper fixes from Mike Snitzer:

 - Quite a few DM zoned target fixes and a Zone append fix in DM core.

   Considering the amount of dm-zoned changes that went in during the
   5.8 merge window these fixes are not that surprising.

 - A fix to Documentation index to include DM ebs target docs.

 - Small cleanup to use struct_size() in DM core's retrieve_deps().

      Merge tag 'kgdb-5.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux · 6116dea8
      Linus Torvalds authored 
      Pull kgdb fixes from Daniel Thompson:
 "The main change here is a fix for a number of unsafe interactions
  between kdb and the console system. The fixes are specific to kdb
  (pure kgdb debugging does not use the console system at all). On
  systems with an NMI then kdb, if it is enabled, must get messages to
  the user despite potentially running from some "difficult" calling
  contexts. These fixes avoid using the console system where we have
  been provided an alternative (safer) way to interact with the user
  and, if using the console system in unavoidable, use oops_in_progress
  for deadlock avoidance. These fixes also ensure kdb honours the
  console enable flag.

  Also included is a fix that wraps kgdb trap handling in an RCU read
  lock to avoids triggering diagnostic warnings. This is a wide lock
  scope but this is OK because kgdb is a stop-the-world debugger. When
  we stop the world we put all the CPUs into holding pens and this
  inhibits RCU update anyway"

* tag 'kgdb-5.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux:
  kgdb: Avoid suspicious RCU usage warning
  kdb: Switch to use safer dbg_io_ops over console APIs
  kdb: Make kdb_printf() console handling more robust
  kdb: Check status of console prior to invoking handlers
  kdb: Re-factor kdb_printf() message write code

      Linus Torvalds authored 
      Pull RISC-V fixes from Palmer Dabbelt:
 "This contains a handful of fixes I'd like to target for rc3.

  Most of them fix issues with the conversion of our vDSO to C. There is
  also one fix to the SiFive PRCI driver that I picked up as it's
  causing boot issues on the hardware.

   - A fix to allow kernels with dynamic ftrace to use the vDSO.

   - Some build fixes for the C vDSO functions.

   - A fix to the PRCI driver's memory allocation, which was the cause
     of some boot panics with FREELIST_RANDOM"

* tag 'riscv-for-linus-5.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
  riscv: Fixup __vdso_gettimeofday broke dynamic ftrace

  clk: sifive: allocate sufficient memory for struct __prci_data
  riscv: Add -fPIC option to CFLAGS_vgettimeofday.o

      Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux · 8530684f
      Linus Torvalds authored 
      Pull arm64 fixes from Will Deacon:
 "The big fix here is to our vDSO sigreturn trampoline as, after a
  painfully long stint of debugging, it turned out that fixing some of
  our CFI directives in the merge window lit up a bunch of logic in
  libgcc which has been shown to SEGV in some cases during asynchronous
  pthread cancellation.

  It looks like we can fix this by extending the directives to restore
  most of the interrupted register state from the sigcontext, but it's
  risky and hard to test so we opted to remove the CFI directives for
  now and rely on the unwinder fallback path like we used to.

   - Fix unwinding through vDSO sigreturn trampoline

   - Fix build warnings by raising minimum LD version for PAC

   - Whitelist some Kryo Cortex-A55 derivatives for Meltdown and SSB

   - Fix perf register PC reporting for compat tasks

   - Fix 'make clean' warning for arm64 signal selftests

   - Fix ftrace when BTI is compiled in

   - Avoid building the compat vDSO using GCC plugins"

  kselftest: arm64: Remove redundant clean target
  arm64: kpti: Add KRYO{3, 4}XX silver CPU cores to kpti safelist
  arm64: Don't insert a BTI instruction at inner labels
  arm64: vdso: Don't use gcc plugins for building vgettimeofday.c
  arm64: vdso: Only pass --no-eh-frame-hdr when linker supports it
  arm64: Depend on newer binutils when building PAC
  arm64: compat: Remove 32-bit sigreturn code from the vDSO
  arm64: compat: Always use sigpage for sigreturn trampoline
  arm64: compat: Allow 32-bit vdso and sigpage to co-exist
