Commit 8a56038c ("Yama: consolidate error reporting") causes lockups
when someone hits a Yama denial. Call chain:

process_vm_readv -> process_vm_rw -> process_vm_rw_core -> mm_access
-> ptrace_may_access
task_lock(...) is taken
__ptrace_may_access -> security_ptrace_access_check
-> yama_ptrace_access_check -> report_access -> kstrdup_quotable_cmdline
-> get_cmdline -> access_process_vm -> get_task_mm
task_lock(...) is taken again

task_lock(p) just calls spin_lock(&p->alloc_lock), so at this point,
spin_lock() is called on a lock that is already held by the current
process.

Also: Since the alloc_lock is a spinlock, sleeping inside
security_ptrace_access_check hooks is probably not allowed at all? So it's
not even possible to print the cmdline from in there because that might
involve paging in userspace memory.

It would be tempting to rewrite ptrace_may_access() to drop the alloc_lock
before calling the LSM, but even then, ptrace_may_access() itself might be
called from various contexts in which you're not allowed to sleep; for
example, as far as I understand, to be able to hold a reference to another
task, usually an RCU read lock will be taken (see e.g. kcmp() and
get_robust_list()), so that also prohibits sleeping. (And using e.g. FUSE,
a user can cause pagefault handling to take arbitrary amounts of time -
see https://bugs.chromium.org/p/project-zero/issues/detail?id=808.)

Therefore, AFAIK, in order to print the name of a process below
security_ptrace_access_check(), you'd have to either grab a reference to
the mm_struct and defer the access violation reporting or just use the
"comm" value that's stored in kernelspace and accessible without big
complications. (Or you could try to use some kind of atomic remote VM
access that fails if the memory isn't paged in, similar to
copy_from_user_inatomic(), and if necessary fall back to comm, but
that'd be kind of ugly because the comm/cmdline choice would look
pretty random to the user.)

Fix it by deferring reporting of the access violation until current
exits kernelspace the next time.

v2: Don't oops on PTRACE_TRACEME, call report_access under
task_lock(current). Also fix nonsensical comment. And don't use
GPF_ATOMIC for memory allocation with no locks held.
This patch is tested both for ptrace attach and ptrace traceme.

 "These are two stable-candidate fixes (PM core, cpuidle) and a bunch of

  Specifics:

   - Stable-candidate cpuidle fix to make it check the right variable
     when deciding whether or not to enable interrupts on the local CPU
     so as to avoid enabling iterrupts too early in some cases if the
     system has both coupled and per-core idle states (Daniel Lezcano).

   - Stable-candidate PM core fix to make it handle failures at the
     "late suspend" stage of device suspend consistently for all devices
     regardless of whether or not async suspend/resume is enabled for
     them (Rafael Wysocki).

   - Cleanups in the cpufreq core, the schedutil governor and the
     intel_pstate driver (Rafael Wysocki, Pankaj Gupta, Viresh Kumar)"

* tag 'pm-4.7-rc1-more' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  PM / sleep: Handle failures in device_suspend_late() consistently
  cpufreq: schedutil: Improve prints messages with pr_fmt
  cpuidle: Fix cpuidle_state_is_coupled() argument in cpuidle_enter()
  cpufreq: simplified goto out in cpufreq_register_driver()
  cpufreq: governor: CPUFREQ_GOV_STOP never fails
  cpufreq: governor: CPUFREQ_GOV_POLICY_EXIT never fails
  intel_pstate: Simplify conditional in intel_pstate_set_policy()

the only case when we should skip the iterate_and_advance() guts
is when nothing's left in the iterator, _not_ just when requested
amount is 0.  Said guts will do nothing in the latter case anyway;
the problem we tried to deal with in the aforementioned commit is
that when there's nothing left *and* the amount requested is 0,
we might end up deferencing one iovec too many; the value we fetch
from there is discarded in that case, but theoretically it might
oops if the iovec array ends exactly at the end of page with the
next page not mapped.

Bailing out on zero size requested had an unexpected side effect -
zero-length segment in the beginning of iovec array ended up
throwing do_loop_readv_writev() into infinite spin; we do not
advance past the empty segment at all.  Reproducer is trivial:
echo '#include <sys/uio.h>' >a.c
echo 'main() {char c; struct iovec v[] = {{&c,0},{&c,1}}; readv(0,v,2);}' >>a.c
cc a.c && ./a.out </proc/uptime

which should end up with the process not hanging.  Probably ought to
go into LTP or xfstests...

Pull pwm updates from Thierry Reding:
 "This set of changes introduces an atomic API to the PWM subsystem.
  This is influenced by the DRM atomic API that was introduced a while
  back, though it is obviously a lot simpler.  The fundamental idea
  remains the same, though: drivers provide a single callback to
  implement the atomic configuration of a PWM channel.

  As a side-effect the PWM subsystem gains the ability for initial state
  retrieval, so that the logical state mirrors that of the hardware.
  Many use-cases don't care about this, but for others it is essential.

  These new features require changes in all users, which these patches
  take care of.  The core is transitioned to use the atomic callback if
  available and provides a fallback mechanism for other drivers.

  Changes to transition users and drivers to the atomic API are
  postponed to v4.8"

  b5179ac7 ("sched/fair: Prepare to fix fairness problems on migration")

... introduced a bug: Mike Galbraith found that it introduced a
performance regression, while Paul E. McKenney reported lost
wakeups and bisected it to this commit.

The reason is that I mis-read ttwu_queue() such that I assumed any
wakeup that got a remote queue must have had the task migrated.

Since this is not so; we need to transfer this information between
queueing the wakeup and actually doing the wakeup. Use a new
task_struct::sched_flag for this, we already write to
sched_contributes_to_load in the wakeup path so this is a hot and
modified cacheline.

With the change to sparse IRQs, the lpc32xx platform gets a warning about
conflicting macros:

In file included from arch/arm/mach-lpc32xx/irq.c:31:0:
arch/arm/mach-lpc32xx/include/mach/irqs.h:115:0: warning: "NR_IRQS" redefined
 #define NR_IRQS    96
arch/arm/include/asm/irq.h:9:0: note: this is the location of the previous definition
 #define NR_IRQS NR_IRQS_LEGACY

One such instance was in the old irq driver that is now removed by
the previous patch, but any other file including mach/irqs.h still
has the issue. Since none of them use this constant, we can just
remove the old definition.

New NXP LPC32xx irq chip driver is used instead of a legacy one.

Pull spi updates from Mark Brown:
 "Another quiet release for SPI, almost entirely driver specific changes
  with the diffstat dominated by two new drivers which are about two
  thirds of it in terms of lines of code:

   - new drivers for PIC32 standard and SQI controllers
   - the Cadence driver has had runtime PM support added and quite a few
     fixes and cleanups
   - flash-specific accelerated path support now has a feature query
     interface
   - the pxa2xx driver has been moved to use the core DMA mapping support"

 "First cycle with Boris as NAND maintainer! Many (most) bullets stolen
  from him.

  Generic:
   - Migrated NAND LED trigger to be a generic MTD trigger

  NAND:
   - Introduction of the "ECC algorithm" concept, to avoid overloading
     the ECC mode field too much more
   - Replaced the nand_ecclayout infrastructure with something a little
     more flexible (finally!) and future proof
   - Rework of the OMAP GPMC and NAND drivers; the TI folks pulled some
     of this into their own tree as well
   - Prepare the sunxi NAND driver to receive DMA support
   - Handle bitflips in erased pages on GPMI revisions that do not
     support this in hardware.

  SPI NOR:
   - Start using the spi_flash_read() API for SPI drivers that support
     it (i.e., SPI drivers with special memory-mapped flash modes)

  And other small scattered improvments"

Instead of having two functions for cycling through the E820 map in
order to count to be remapped pages and remap them later, just use one
function with a caller supplied sub-function called for each region to
be processed. This eliminates the possibility of a mismatch between
both loops which showed up in certain configurations.

Commit ff1e22e7 ("xen/events: Mask a moving irq") open-coded
irq_move_irq() but left out checking if the IRQ is disabled. This broke
resuming from suspend since it tries to move a (disabled) irq without
holding the IRQ's desc->lock. Fix it by adding in a check for disabled
IRQs.

b4ff8389 is incomplete: relies on nr_legacy_irqs() to get the number

probe_8259A(). Use NR_IRQS_LEGACY instead.
