5cbb80d523 ARM: dts: imx7d-zii-rmu2: fix rgmii phy-mode for ksz9031 phy
Since commit bcf3440c6d ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY") the networking is broken on the imx7d-zii-rmu2 board.

The end result is that network receive behaviour is marginal with lots of
RX CRC errors experienced and NFS frequently failing.

Quoting the explanation from Andrew Lunn in commit 0672d22a19
("ARM: dts: imx: Fix the AR803X phy-mode"):

"The problem here is, all the DTs were broken since day 0. However,
because the PHY driver was also broken, nobody noticed and it
worked. Now that the PHY driver has been fixed, all the bugs in the
DTs now become an issue"

Fix it by switching to phy-mode = "rgmii-id".

  on the machine.
- Select CONFIG_DRM_DISPLAY_CONNECTOR=y, the
  CONFIG_DRM_SIMPLE_BRIDGE was renamed when renaming the

  the display connector bridge, in order to work, so this
  is required to have graphics working properly in kernel

 "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"

6f6aea7e96 parisc: fix PMD pages allocation by restoring pmd_alloc_one()
Commit 1355c31eeb ("asm-generic: pgalloc: provide generic pmd_alloc_one()
and pmd_free_one()") converted parisc to use generic version of
pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for
PMD.

Restore the original version of pmd_alloc_one() for parisc, just use
GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and
memset.

d84835b118 A RISC-V Fix for 5.9
I collected a single fix during the merge window: we managed to break the early
 trap setup on !MMU, this patch fixes it.
 
 The power keeps going on here so I haven't have a chance to give this the
 testing I usually would, but I don't have a Kendryte anyway so I doubt I'd pick
 up anything subtle even if I was to test.  The patch seems pretty safe and it's
 still early, so I don't see any reason to let it sit around.
 
 It's fairly late so if it misses the merge window that's not a big deal.  I'll
 definately have stuff for next week, so I'll just start from whenever this
 lands.

f91daf565b io_uring: short circuit -EAGAIN for blocking read attempt
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.

d4e7cd36a9 io_uring: sanitize double poll handling
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.

713eee8472 perf tools changes for v5.9: 2nd batch
Fixes:
 
 - Fixes for 'perf bench numa'.
 
 - Always memset source before memcpy in 'perf bench mem'.
 
 - Quote CC and CXX for their arguments to fix build in environments using
   those variables to pass more than just the compiler names.
 
 - Fix module symbol processing, addressing regression detected via "perf test".
 
 - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf test' entry.
 
 Improvements:
 
 - Add script to autogenerate socket family name id->string table from copy of
   kernel header, used so far in 'perf trace'.
 
 - 'perf ftrace' improvements to provide similar options for this utility so
   that one can go from 'perf record', 'perf trace', etc to 'perf ftrace' just
   by changing the name of the subcommand.
 
 - Prefer new "sched:sched_waking" trace event when it exists in 'perf sched'
   post processing.
 
 - Update POWER9 metrics to utilize other metrics.
 
 - Fall back to querying debuginfod if debuginfo not found locally.
 
 Miscellaneous:
 
 - Sync various kvm headers with kernel sources.
 
 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
 
 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.
 
 fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
 works), fixes will be provided soon.
 
 clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.

Merge tag 'perf-tools-2020-08-14' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tools updates from Arnaldo Carvalho de Melo:
 "Fixes:
   - Fixes for 'perf bench numa'.

   - Always memset source before memcpy in 'perf bench mem'.

   - Quote CC and CXX for their arguments to fix build in environments
     using those variables to pass more than just the compiler names.

   - Fix module symbol processing, addressing regression detected via
     "perf test".

   - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
     test' entry.

  Improvements:
   - Add script to autogenerate socket family name id->string table from
     copy of kernel header, used so far in 'perf trace'.

   - 'perf ftrace' improvements to provide similar options for this
     utility so that one can go from 'perf record', 'perf trace', etc to
     'perf ftrace' just by changing the name of the subcommand.

   - Prefer new "sched:sched_waking" trace event when it exists in 'perf
     sched' post processing.

   - Update POWER9 metrics to utilize other metrics.

   - Fall back to querying debuginfod if debuginfo not found locally.

  Miscellaneous:
   - Sync various kvm headers with kernel sources"

fe0580ac5c virtio: pci: constify ioreadX() iomem argument (as in generic implementation)
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

8f28ca6bd8 iomap: constify ioreadX() iomem argument (as in generic implementation)
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.

f9e7ff9c6f sh: use generic strncpy()
Current SH will get below warning at strncpy()

${LINUX}/drivers/mmc/host/vub300.c: In function 'new_system_port_status':
${LINUX}/arch/sh/include/asm/string_32.h:51:42: warning: array subscript\
  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.
