The drivers/pinctrl/sh-pfc subdirectory was originally created to group
pin control drivers for various Renesas SuperH and SH-Mobile platforms.
However, the name "sh-pfc" no longer reflects its contents, as the
directory now contains pin control drivers for Renesas SuperH, ARM32,
and ARM64 SoCs.Hence rename the subdirectory from drivers/pinctrl/sh-pfc to
drivers/pinctrl/renesas, and the related Kconfig symbol from
PINCTRL_SH_PFC to PINCTRL_RENESAS.Rename the git branch in MAINTAINERS, too, for consistency.

For pins requiring software driven IO output operations, the RZ/A1 Pin
Controller uses either the "output-high" or "output-low" DT property to
enable the corresponding output buffer. The actual line value doesn't
matter, as it is ignored.Commit 425562429d4f3b13 ("pinctrl: generic: Add output-enable property")
introduced a new DT property for this specific use case.Update the RZ/A1 Pin Controller DT bindings and driver to use this new
property instead. Preserve backwards compatibility with old DTBs in the
driver, as this comes at a very small cost.Notes:
- The DT binding examples already used the new property,
- There are no upstream users of the old properties.Signed-off-by: Geert Uytterhoeven

"A few differerent things in here.Seems like syzbot got some more io_uring bits wired up, and we got a
handful of reports and the associated fixes are in here.General fixes too, and a lot of them marked for stable.
Lastly, a bit of fallout from the async buffered reads, where we now
more easily trigger short reads. Some applications don't really like
that, so the io_read() code now handles short reads internally, and
got a cleanup along the way so that it's now easier to read (and
documented). We're now passing tests that failed before"* tag 'io_uring-5.9-2020-08-15' of git://git.kernel.dk/linux-block:

One case was missed in the short IO retry handling, and that's hitting
-EAGAIN on a blocking attempt read (eg from io-wq context). This is a
problem on sockets that are marked as non-blocking when created, they
don't carry any REQ_F_NOWAIT information to help us terminate them
instead of perpetually retrying.Fixes: 227c0c9673d8 ("io_uring: internally retry short reads")

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.Cc: stable@vger.kernel.org # v5.8

The ioreadX() helpers have inconsistent interface. On some architectures
void *__iomem address argument is a pointer to const, on some not.Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.Signed-off-by: Krzysztof Kozlowski

Patch series "iomap: Constify ioreadX() iomem argument", v3.
The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.It seems there is nothing really stopping all of them to take pointer to
const.This patch (of 4):
The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On
some architectures void *__iomem address argument is a pointer to const,
on some not.Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.[krzk@kernel.org: sh: clk: fix assignment from incompatible pointer type for ioreadX()]

80 is above array bounds of 'char[26]' [-Warray-bounds]
: "0" (__dest), "1" (__src), "r" (__src+__n)
~~~~~^~~~In general, strncpy() should behave like below.
char dest[10];
char *src = "12345";strncpy(dest, src, 10);
// dest = {'1', '2', '3', '4', '5',
'\0','\0','\0','\0','\0'}But, current SH strnpy() has 2 issues.
1st is it will access to out-of-memory (= src + 10).
2nd is it needs big fixup for it, and maintenance __asm__
code is difficult.To solve these issues, this patch simply uses generic strncpy()
instead of architecture specific one.Signed-off-by: Kuninori Morimoto
