Volume is a little higher than usual due to a set of gpio fixes for
Davinci platforms that's been around a while, still seemed appropriate
to not hold off until next merge window.
Besides that it's the usual mix of minor fixes, mostly corrections of
small stuff in device trees.
Major stability-related one is the removal of a regulator from DT on
Rock960, since DVFS caused undervoltage. I expect it'll be restored once
they figure out the underlying issue.

Pull STIBP fallout fixes from Thomas Gleixner:
"The performance destruction department finally got it's act together
and came up with a cure for the STIPB regression:
- Provide a command line option to control the spectre v2 user space
mitigations. Default is either seccomp or prctl (if seccomp is
disabled in Kconfig). prctl allows mitigation opt-in, seccomp
enables the migitation for sandboxed processes.
- Rework the code to handle the conditional STIBP/IBPB control and
remove the now unused ptrace_may_access_sched() optimization
attempt
- Disable STIBP automatically when SMT is disabled
- Optimize the switch_to() logic to avoid MSR writes and invocations
of __switch_to_xtra().
- Make the asynchronous speculation TIF updates synchronous to
prevent stale mitigation state.
As a general cleanup this also makes retpoline directly depend on
compiler support and removes the 'minimal retpoline' option which just
pretended to provide some form of security while providing none"

PCI: dwc: Fix MSI-X EP framework address calculation bug
PCI: layerscape: Fix wrong invocation of outbound window disable accessor
PCI: imx6: Fix link training status detection in link up check
The macros PCI_EXP_LNKCAP_SLS_*GB are values, not bit masks. We must mask
the register and compare it against them.
This fixes errors like this:
amdgpu: [powerplay] failed to send message 261 ret is 0
when a PCIe-v3 card is plugged into a PCIe-v1 slot, because the slot is
being incorrectly reported as PCIe-v3 capable.
6cf57be0f7, which appeared in v4.17, added pcie_get_speed_cap() with the
incorrect test of PCI_EXP_LNKCAP_SLS as a bitmask. 5d9a633040, which
appeared in v4.19, changed amdgpu to use pcie_get_speed_cap(), so the
amdgpu bug reports below are regressions in v4.19.

Pull fscache and cachefiles fixes from David Howells:
"Misc fixes:
- Fix an assertion failure at fs/cachefiles/xattr.c:138 caused by a
race between a cache object lookup failing and someone attempting
to reenable that object, thereby triggering an update of the
object's attributes.
- Fix an assertion failure at fs/fscache/operation.c:449 caused by a
split atomic subtract and atomic read that allows a race to happen.
- Fix a leak of backing pages when simultaneously reading the same
page from the same object from two or more threads.
- Fix a hang due to a race between a cache object being discarded and
the corresponding cookie being reenabled.
There are also some minor cleanups:
- Cast an enum value to a different enum type to prevent clang from
generating a warning. This shouldn't cause any sort of change in
the emitted code.
- Use ktime_get_real_seconds() instead of get_seconds(). This is just
used to uniquify a filename for an object to be placed in the
graveyard. Objects placed there are deleted by cachfilesd in
userspace immediately thereafter.
- Remove an initialised, but otherwise unused variable. This should
have been entirely optimised away anyway"

The linux-mips.org infrastructure has been unreliable recently & nobody
with sufficient access to fix it is around to do so. As a result we're
moving away from it, and part of this is migrating our mailing list to
kernel.org.
Replace all instances of linux-mips@linux-mips.org in MAINTAINERS with
the shiny new linux-mips@vger.kernel.org address.
The new list is now being archived on kernel.org at
https://lore.kernel.org/linux-mips/ which also holds the history of the
old linux-mips.org list.
