These apply to today's mmotm. Some merge notes:
* The missing item ("mremap_dontunmap") at the *top* of .gitignore
for this patch will also being applied to linux.git in a separate
patch [1].
The other missing item ("khugepaged") is added to *bottom* of
.gitignore. This approach allows merging to work without manual
intervention in this case.

2.26.2
Please consider this version series ready for upstream acceptance.
This patch series adds partial read support in request_firmware_into_buf.
In order to accept the enhanced API it has been requested that kernel
selftests and upstreamed driver utilize the API enhancement and so
are included in this patch series.
Also in this patch series is the addition of a new Broadcom VK driver
utilizing the new request_firmware_into_buf enhanced API.
Changes from v4:
- handle reset issues if card crashes
- allow driver to have min required msix
- add card utilization information
Changes from v3:
- fix sparse warnings
- fix printf format specifiers for size_t
- fix 32-bit cross-compiling reports 32-bit shifts
- use readl/writel,_relaxed to access pci ioremap memory,
removed memory barriers and volatile keyword with such change
- driver optimizations for interrupt/poll functionalities
Changes from v2:
- remove unnecessary code and mutex locks in lib/test_firmware.c
- remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead
- remove bitfields
- remove Kconfig default m
- adjust formatting and some naming based on feedback
- fix error handling conditions
- use appropriate return codes
- use memcpy_toio instead of direct access to PCIE bar

2.17.1
The test driver uses an xa_array to store virtual to physical address
translations for a simulated hardware device. The MMU notifier
invalidation callback is used to keep the table consistent with the CPU
page table and is frequently called only for a page or two. However, if
the test process exits unexpectedly or is killed, the range can be
[0..ULONG_MAX] in which case calling xa_erase() for every possible PFN
results in CPU timeouts. Munmap() can result in a large range being
invalidated but in that case, the xa_array is likely to contain entries
that need to be invalidated.
Check for [0..ULONG_MAX] explicitly and just destroy the whole table.

This patch is based on Jason Gunthorpe's hmm tree and should be folded
into the ("mm/hmm/test: add selftest driver for HMM") patch once this
patch is reviewed, etc.

2.25.1
This patch series consists of first round of fixes to integrate
Kselftest into Kernel CI.
You can find full list of problems in my announcement I sent out
last week:
https://lkml.org/lkml/2020/2/27/2221
These fixes to android and seccomp tests address relocatable support.
However, they will still leave the source directory dirty.
android test does headers_install in source directory. This is an easier
problem to fix. seccomp on the other hand builds fixdep scripts under
scripts/basic and installs headers in the source directory. It is linked
to solving bpf relocatable build issue which I haven't given it a lot of
thought for now.
There is no dependency on source directory for run-time which is what
we want.
I will apply these kernelci topic branch for testing
