      tools headers uapi: Sync asm-generic/mman-common.h and linux/mman.h · be709d48
      Arnaldo Carvalho de Melo authored 
      To deal with the move of some defines from asm-generic/mmap-common.h to
linux/mman.h done in:

  746c9398 ("arch: move common mmap flags to linux/mman.h")

The generated mmap_flags array stays the same:

  $ tools/perf/trace/beauty/mmap_flags.sh
  static const char *mmap_flags[] = {
	[ilog2(0x40) + 1] = "32BIT",
	[ilog2(0x01) + 1] = "SHARED",
	[ilog2(0x02) + 1] = "PRIVATE",
	[ilog2(0x10) + 1] = "FIXED",
	[ilog2(0x20) + 1] = "ANONYMOUS",
	[ilog2(0x100000) + 1] = "FIXED_NOREPLACE",
	[ilog2(0x0100) + 1] = "GROWSDOWN",
	[ilog2(0x0800) + 1] = "DENYWRITE",
	[ilog2(0x1000) + 1] = "EXECUTABLE",
	[ilog2(0x2000) + 1] = "LOCKED",
	[ilog2(0x4000) + 1] = "NORESERVE",

	[ilog2(0x40000) + 1] = "HUGETLB",
	[ilog2(0x80000) + 1] = "SYNC",
  };
  $

And to have the system's sys/mman.h find the definition of MAP_SHARED
and MAP_PRIVATE, make sure they are defined in the tools/ mman-common.h
in a way that keeps it the same as the kernel's, need for keeping the
Android's NDK cross build working.

This silences these perf build warnings:

      perf evsel: Fix max perf_event_attr.precise_ip detection · 4e8a5c15
      Jiri Olsa authored 
      After a discussion with Andi, move the perf_event_attr.precise_ip
detection for maximum precise config (via :P modifier or for default
cycles event) to perf_evsel__open().

The current detection in perf_event_attr__set_max_precise_ip() is
tricky, because precise_ip config is specific for given event and it
currently checks only hw cycles.

We now check for valid precise_ip value right after failing
sys_perf_event_open() for specific event, before any of the
perf_event_attr fallback code gets executed.

This way we get the proper config in perf_event_attr together with
allowed precise_ip settings.

We can see that code activity with -vv, like:

  $ perf record -vv ls
  ...

      perf intel-pt: Fix TSC slip · f3b4e06b
      Adrian Hunter authored 
      A TSC packet can slip past MTC packets so that the timestamp appears to
go backwards. One estimate is that can be up to about 40 CPU cycles,
which is certainly less than 0x1000 TSC ticks, but accept slippage an
order of magnitude more to be on the safe side.

      afs: Fix StoreData op marshalling · 8c7ae38d
      David Howells authored 
      The marshalling of AFS.StoreData, AFS.StoreData64 and YFS.StoreData64 calls
generated by ->setattr() ops for the purpose of expanding a file is
incorrect due to older documentation incorrectly describing the way the RPC
'FileLength' parameter is meant to work.

The older documentation says that this is the length the file is meant to
end up at the end of the operation; however, it was never implemented this
way in any of the servers, but rather the file is truncated down to this
before the write operation is effected, and never expanded to it (and,
indeed, it was renamed to 'TruncPos' in 2014).

Fix this by setting the position parameter to the new file length and doing
a zero-lengh write there.

The bug causes Xwayland to SIGBUS due to unexpected non-expansion of a file
it then mmaps.  This can be tested by giving the following test program a
filename in an AFS directory:

	#include <stdio.h>
	#include <stdlib.h>
	#include <unistd.h>
	#include <fcntl.h>
	#include <sys/mman.h>
	int main(int argc, char *argv[])
	{
		char *p;
		int fd;
		if (argc != 2) {
			fprintf(stderr,
				"Format: test-trunc-mmap <file>\n");
			exit(2);
		}
		fd = open(argv[1], O_RDWR | O_CREAT | O_TRUNC);
		if (fd < 0) {
			perror(argv[1]);
			exit(1);
		}
		if (ftruncate(fd, 0x140008) == -1) {
			perror("ftruncate");
			exit(1);
		}
		p = mmap(NULL, 4096, PROT_READ | PROT_WRITE,
			 MAP_SHARED, fd, 0);
		if (p == MAP_FAILED) {
			perror("mmap");
			exit(1);
		}
		p[0] = 'a';
		if (munmap(p, 4096) < 0) {
			perror("munmap");
			exit(1);
		}
		if (close(fd) < 0) {
			perror("close");
			exit(1);
		}
		exit(0);
	}

The variable is now accessed in proper context. Use
get_cpu_var()/put_cpu_var() pair to disable
preemption during access.
As the hardware authorization settings apply to all CPUs, it
does not matter which CPU is used to check the authorization setting.

Remove the event->count assignment. It is not needed as function
perf_event_alloc() allocates memory for the event with kzalloc() and
thus count is already set to zero.

Supid says:
 "Due to the new device model daisy driver will now try to find the
  parallel ports while trying to register its driver so that it can bind
  with them. Now, since daisy driver is loaded while parport bus is
  initialising the list of parport is still empty and it tries to load
  the lowlevel driver, which has an alias set to parport_pc, now causes
  a deadlock"

But I don't think the daisy driver should be loaded by the parport
initialization in the first place, so let's revert the whole change.

If the daisy driver can just initialize separately on its own (like a
driver should), instead of hooking into the parport init sequence
directly, this issue probably would go away.

      arm64: tegra: Disable CQE Support for SDMMC4 on Tegra186 · 93958742
      Jonathan Hunter authored 
      Enabling CQE support on Tegra186 Jetson TX2 has introduced a regression
that is causing accesses to the file-system on the eMMC to fail. Errors
such as the following have been observed ...

 mmc2: running CQE recovery
 mmc2: mmc_select_hs400 failed, error -110
 print_req_error: I/O error, dev mmcblk2, sector 8 flags 80700
 mmc2: cqhci: CQE failed to exit halt state

For now disable CQE support for Tegra186 until this issue is resolved.

i.MX fixes for 5.1:
 - Correct phy mode setting of imx6dl-yapp4 board to fix a problem
   caused by commit 5ecdd77c ("net: dsa: qca8k: disable delay
   for RGMII mode").
 - Add a missing of_node_put call to fix leaked reference detected by
   coccinelle in imx51 machine code.
 - Fix imx6q cpuidle driver bug which causes that CPU might not wake up
   at expected time.
 - Increase reset duration of Ethernet phy Micrel KSZ9031RNX to fix
   transmission timeouts error seen on imx6qdl-phytec-pfla02 board.
 - Correct SPDX License Identifier style for imx6ull-pinfunc-snvs.h.
 - Fix 'bus-witdh' typos in imx6qdl-icore-rqs.dtsi.
 - Correct pseudo PHY address of switch device for imx6dl-yapp4 board.
 - Update PWM driver options in imx defconfig files due to the change
   on driver part.

      ARM: dts: nomadik: Fix polarity of SPI CS · fa946356
      Linus Walleij authored 
      The SPI DT bindings are for historical reasons a pitfall,
the ability to flag a GPIO line as active high/low with
the second cell flags was introduced later so the SPI
subsystem will only accept the bool flag spi-cs-high
to indicate that the line is active high.

It worked by mistake, but the mistake was corrected
in another commit.

The comment in the DTS file was also misleading: this
CS is indeed active high.
