   - Avoid registering a platform device by the ti-cpufreq driver on
     platforms that cannot use it (Dave Gerlach).

   - Fix a mistake in the ti-opp-supply operating performance points

     closely match the behaviour we used to have with bootmem, which

      Documentation/security-bugs: Postpone fix publication in exceptional cases · 544b03da
      Will Deacon authored 
      At the request of the reporter, the Linux kernel security team offers to
postpone the publishing of a fix for up to 5 business days from the date
of a report.

While it is generally undesirable to keep a fix private after it has
been developed, this short window is intended to allow distributions to
package the fix into their kernel builds and permits early inclusion of
the security team in the case of a co-ordinated disclosure with other
parties. Unfortunately, discussions with major Linux distributions and
cloud providers has revealed that 5 business days is not sufficient to
achieve either of these two goals.

As an example, cloud providers need to roll out KVM security fixes to a
global fleet of hosts with sufficient early ramp-up and monitoring. An
end-to-end timeline of less than two weeks dramatically cuts into the
amount of early validation and increases the chance of guest-visible
regressions.

The consequence of this timeline mismatch is that security issues are
commonly fixed without the involvement of the Linux kernel security team
and are instead analysed and addressed by an ad-hoc group of developers
across companies contributing to Linux. In some cases, mainline (and
therefore the official stable kernels) can be left to languish for
extended periods of time. This undermines the Linux kernel security
process and puts upstream developers in a difficult position should they
find themselves involved with an undisclosed security problem that they
are unable to report due to restrictions from their employer.

To accommodate the needs of these users of the Linux kernel and
encourage them to engage with the Linux security team when security
issues are first uncovered, extend the maximum period for which fixes
may be delayed to 7 calendar days, or 14 calendar days in exceptional
cases, where the logistics of QA and large scale rollouts specifically
need to be accommodated. This brings parity with the linux-distros@
maximum embargo period of 14 calendar days.

      mtd: spi-nor: fix selection of uniform erase type in flexible conf · e8828ec1
      Tudor.Ambarus@microchip.com authored 
      There are uniform, non-uniform and flexible erase flash configurations.

The non-uniform erase types, are the erase types that can _not_ erase
the entire flash by their own.

As the code was, in case flashes had flexible erase capabilities
(support both uniform and non-uniform erase types in the same flash
configuration) and supported multiple uniform erase type sizes, the
code did not sort the uniform erase types, and could select a wrong
erase type size.

Sort the uniform erase mask in case of flexible erase flash
configurations, in order to select the best uniform erase type size.

Uniform, non-uniform, and flexible configurations with just a valid
uniform erase type, are not affected by this change.

Uniform erase tested on mx25l3273fm2i-08g and sst26vf064B-104i/sn.
Non uniform erase tested on sst26vf064B-104i/sn.

      riscv: add asm/unistd.h UAPI header · 27f8899d
      David Abdurachmanov authored 
      Marcin Juszkiewicz reported issues while generating syscall table for riscv
using 4.20-rc1. The patch refactors our unistd.h files to match some other
architectures.

- Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
- Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
- Adjust kernel asm/unistd.h

So now asm/unistd.h UAPI header should show all syscalls for riscv.

Before this, Makefile simply put `#include <asm-generic/unistd.h>` into
generated asm/unistd.h UAPI header thus user didn't see:

- __NR_riscv_flush_icache
- __NR_newfstatat
- __NR_fstat

which are supported by riscv kernel.

      This patch extends Linux RISC-V build system to build and install:
Image - Flat uncompressed kernel image
Image.gz - Flat and GZip compressed kernel image

Quiet a few bootloaders (such as Uboot, UEFI, etc) are capable of
booting flat and compressed kernel images. In case of Uboot, booting
Image or Image.gz is achieved using bootm command.

The flat and uncompressed kernel image (i.e. Image) is very useful
in pre-silicon developent and testing because we can create back-door
HEX files for RAM on FPGAs from Image.
