  "powerpc fixes for 4.19 #3

   A reasonably big batch of fixes due to me being away for a few weeks.

   A fix for the TM emulation support on Power9, which could result in
   corrupting the guest r11 when running under KVM.

   Two fixes to the TM code which could lead to userspace GPR corruption
   if we take an SLB miss at exactly the wrong time.

   Our dynamic patching code had a bug that meant we could patch freed
   __init text, which could lead to corrupting userspace memory.

   csum_ipv6_magic() didn't work on little endian platforms since we
   optimised it recently.

   A fix for an endian bug when reading a device tree property telling
   us how many storage keys the machine has available.

   Fix a crash seen on some configurations of PowerVM when migrating the
   partition from one machine to another.

   A fix for a regression in the setup of our CPU to NUMA node mapping
   in KVM guests.

   A fix to our selftest Makefiles to make them work since a recent
   change to the shared Makefile logic."

7e0cf1c983 selftests/powerpc: Fix Makefiles for headers_install change
Commit b2d35fa5fc ("selftests: add headers_install to lib.mk")
introduced a requirement that Makefiles more than one level below the
selftests directory need to define top_srcdir, but it didn't update
any of the powerpc Makefiles.

This broke building all the powerpc selftests with eg:

  make[1]: Entering directory '/src/linux/tools/testing/selftests/powerpc'
  BUILD_TARGET=/src/linux/tools/testing/selftests/powerpc/alignment; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C alignment all
  make[2]: Entering directory '/src/linux/tools/testing/selftests/powerpc/alignment'
  ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory
  make[2]: *** No rule to make target '../../../../scripts/subarch.include'.
  make[2]: Failed to remake makefile '../../../../scripts/subarch.include'.
  Makefile:38: recipe for target 'alignment' failed

Fix it by setting top_srcdir in the affected Makefiles.

Paolo writes:
  "It's mostly small bugfixes and cleanups, mostly around x86 nested
   virtualization.  One important change, not related to nested
   virtualization, is that the ability for the guest kernel to trap
   CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is
   now masked by default.  This is because the feature is detected
   through an MSR; a very bad idea that Intel seems to like more and
   more.  Some applications choke if the other fields of that MSR are
   not initialized as on real hardware, hence we have to disable the
   whole MSR by default, as was the case before Linux 4.12."

50c6b58a81 tls: fix currently broken MSG_PEEK behavior
In kTLS MSG_PEEK behavior is currently failing, strace example:

  [pid  2430] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 3
  [pid  2430] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 4
  [pid  2430] bind(4, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("0.0.0.0")}, 16) = 0
  [pid  2430] listen(4, 10)               = 0
  [pid  2430] getsockname(4, {sa_family=AF_INET, sin_port=htons(38855), sin_addr=inet_addr("0.0.0.0")}, [16]) = 0
  [pid  2430] connect(3, {sa_family=AF_INET, sin_port=htons(38855), sin_addr=inet_addr("0.0.0.0")}, 16) = 0
  [pid  2430] setsockopt(3, SOL_TCP, 0x1f /* TCP_??? */, [7564404], 4) = 0
  [pid  2430] setsockopt(3, 0x11a /* SOL_?? */, 1, "\3\0033\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = 0
  [pid  2430] accept(4, {sa_family=AF_INET, sin_port=htons(49636), sin_addr=inet_addr("127.0.0.1")}, [16]) = 5
  [pid  2430] setsockopt(5, SOL_TCP, 0x1f /* TCP_??? */, [7564404], 4) = 0
  [pid  2430] setsockopt(5, 0x11a /* SOL_?? */, 2, "\3\0033\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = 0
  [pid  2430] close(4)                    = 0
  [pid  2430] sendto(3, "test_read_peek", 14, 0, NULL, 0) = 14
  [pid  2430] sendto(3, "_mult_recs\0", 11, 0, NULL, 0) = 11
  [pid  2430] recvfrom(5, "test_read_peektest_read_peektest"..., 64, MSG_PEEK, NULL, NULL) = 64

As can be seen from strace, there are two TLS records sent,
i) 'test_read_peek' and ii) '_mult_recs\0' where we end up
peeking 'test_read_peektest_read_peektest'. This is clearly
wrong, and what happens is that given peek cannot call into
tls_sw_advance_skb() to unpause strparser and proceed with
the next skb, we end up looping over the current one, copying
the 'test_read_peek' over and over into the user provided
buffer.

Here, we can only peek into the currently held skb (current,
full TLS record) as otherwise we would end up having to hold
all the original skb(s) (depending on the peek depth) in a
separate queue when unpausing strparser to process next
records, minimally intrusive is to return only up to the
current record's size (which likely was what c46234ebb4
("tls: RX path for ktls") originally intended as well). Thus,
after patch we properly peek the first record:

 "A better IDA API:

  The new IDA API is similar to ida_simple_get() but better named.  The

As with many other projects, we use some shmalloc allocator.  At some

And it should be populated straight away.  Check that (MAP_PRIVATE |

3b4cd0ff54 kvm: selftest: add dirty logging test
Test KVM dirty logging functionality.

The test creates a standalone memory slot to test tracking the dirty
pages since we can't really write to the default memory slot which still
contains the guest ELF image.

We have two threads running during the test:

(1) the vcpu thread continuously dirties random guest pages by writting
    a iteration number to the first 8 bytes of the page

(2) the host thread continuously fetches dirty logs for the testing
    memory region and verify each single bit of the dirty bitmap by
    checking against the values written onto the page

Note that since the guest cannot calls the general userspace APIs like
random(), it depends on the host to provide random numbers for the
page indexes to dirty.

Pull tracing updates from Steven Rostedt:

 - Restructure of lockdep and latency tracers

   This is the biggest change. Joel Fernandes restructured the hooks
   from irqs and preemption disabling and enabling. He got rid of a lot
   of the preprocessor #ifdef mess that they caused.

   He turned both lockdep and the latency tracers to use trace events
   inserted in the preempt/irqs disabling paths. But unfortunately,
   these started to cause issues in corner cases. Thus, parts of the
   code was reverted back to where lockdep and the latency tracers just
   get called directly (without using the trace events). But because the
   original change cleaned up the code very nicely we kept that, as well
   as the trace events for preempt and irqs disabling, but they are
   limited to not being called in NMIs.

 - Have trace events use SRCU for "rcu idle" calls. This was required
   for the preempt/irqs off trace events. But it also had to not allow
   them to be called in NMI context. Waiting till Paul makes an NMI safe
   SRCU API.

 - New notrace SRCU API to allow trace events to use SRCU.

 - Addition of mcount-nop option support

 - SPDX headers replacing GPL templates.

 - Various other fixes and clean ups.

 - Some fixes are marked for stable, but were not fully tested before
   the merge window opened.

   - An optimised memcmp implementation using Power7-or-later VMX
     instructions

   - Support for barrier_nospec on some NXP CPUs.

   - Support for flushing the count cache on context switch on some IBM
     CPUs (controlled by firmware), as a Spectre v2 mitigation.

   - A series to enhance the information we print on unhandled signals
     to bring it into line with other arches, including showing the
     offending VMA and dumping the instructions around the fault.

6de4c691ea Merge tag 'gpio-v4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.19 kernel cycle.

  I don't know if anything in particular stands out. Maybe the Aspeed
  coprocessor thing from Benji: Aspeed is doing baseboard management
  chips (BMC's) for servers etc.

  These Aspeed's are ARM processors that exist inside (I guess) Intel
  servers, and they are moving forward to using mainline Linux in those.
  This is one of the pieces of the puzzle to achive that. They are doing
  OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/

  Summary:

  Core changes:

   - Add a new API for explicitly naming GPIO consumers, when needed.

   - Don't let userspace set values on input lines. While we do not
     think anyone would do this crazy thing we better plug the hole
     before someone uses it and think it's a nifty feature.

   - Avoid calling chip->request() for unused GPIOs.

  New drivers/subdrivers:

   - The Mediatek MT7621 is supported which is a big win for OpenWRT and
     similar router distributions using this chip, as it seems every
     major router manufacturer on the planet has made products using
     this chip: https://wikidevi.com/wiki/MediaTek_MT7621

   - The Tegra 194 is now supported.

   - The IT87 driver now supports IT8786E and IT8718F super-IO chips.

   - Add support for Rockchip RK3328 in the syscon GPIO driver.

  Driver changes:

   - Handle the get/set_multiple() properly on MMIO chips with inverted
     direction registers. We didn't have this problem until a new chip
     appear that has get/set registers AND inverted direction bits, OK
     now we handle it.

   - A patch series making more error codes percolate upward properly
     for different errors on gpiochip_lock_as_irq().

   - Get/set multiple for the OMAP driver, accelerating these multiple
     line operations if possible.

   - A coprocessor interface for the Aspeed driver. Sometimes a few GPIO
     lines need to be grabbed by a co-processor for doing automated
     tasks, sometimes they are available as GPIO lines. By adding an
     explicit API in this driver we make it possible for the two line
     consumers to coexist. (This work was made available on the
     ib-aspeed branch, which may be appearing in other pull requests.)

   - Implemented .get_direction() and open drain in the SCH311x driver.

   - Continuing cleanup of included headers in GPIO drivers"
