Linus Torvalds e4f7bdc2ec Merge branch 'for-4.7-zac' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata ZAC support from Tejun Heo:
 "This contains Zone ATA Command support for Shingled Magnetic Recording
  devices.

  In addition to sending the new commands down to the device, as ZAC
  commands depend on getting a lot of responses from the device, piping
  up responses is beefed up too.  However, it doesn't involve changes to
  libata core mechanism or its interaction with upper layers, so I'm not
  expecting too many fallouts.

  Kudos to Hannes for driving SMR support"

Linus Torvalds 1f40c49570 libnvdimm for 4.7
1/ Device DAX for persistent memory:
    Device DAX is the device-centric analogue of Filesystem DAX
    (CONFIG_FS_DAX).  It allows memory ranges to be allocated and mapped
    without need of an intervening file system.  Device DAX is strict,
    precise and predictable.  Specifically this interface:
 
    a) Guarantees fault granularity with respect to a given page size
       (pte, pmd, or pud) set at configuration time.
 
    b) Enforces deterministic behavior by being strict about what fault
       scenarios are supported.
 
    Persistent memory is the first target, but the mechanism is also
    targeted for exclusive allocations of performance/feature differentiated
    memory ranges.
 
 2/ Support for the HPE DSM (device specific method) command formats.
    This enables management of these first generation devices until a
    unified DSM specification materializes.
 
 3/ Further ACPI 6.1 compliance with support for the common dimm
    identifier format.
 
 4/ Various fixes and cleanups across the subsystem.

Merge tag 'libnvdimm-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "The bulk of this update was stabilized before the merge window and
  appeared in -next.  The "device dax" implementation was revised this
  week in response to review feedback, and to address failures detected
  by the recently expanded ndctl unit test suite.

  Not included in this pull request are two dax topic branches (dax
  error handling, and dax radix-tree locking).  These topics were
  deferred to get a few more days of -next integration testing, and to
  coordinate a branch baseline with Ted and the ext4 tree.  Vishal and
  Ross will send the error handling and locking topics respectively in
  the next few days.

  This branch has received a positive build result from the kbuild robot
  across 226 configs.

  Summary:

   - Device DAX for persistent memory: Device DAX is the device-centric
     analogue of Filesystem DAX (CONFIG_FS_DAX).  It allows memory
     ranges to be allocated and mapped without need of an intervening

Linus Torvalds 7639dad93a Three more changes.
1) I forgot that I had another selftest to stress test the ftrace
    instance creation. It was actually suppose to go into the 4.6
    merge window, but I never committed it. I almost forgot about it
    again, but noticed it was missing from your tree.
 
 2) Soumya PN sent me a clean up patch to not disable interrupts when
    taking the tasklist_lock for read, as it's unnecessary because
    that lock is never taken for write in irq context.
 
 3) Newer gcc's can cause the jump in the function_graph code to the
    global ftrace_stub label to be a short jump instead of a long one.
    As that jump is dynamically converted to jump to the trace code to
    do function graph tracing, and that conversion expects a long jump
    it can corrupt the ftrace_stub itself (it's directly after that call).
    One way to prevent gcc from using a short jump is to declare the
    ftrace_stub as a weak function, which we do here to keep gcc from
    optimizing too much.

Linus Torvalds bd28b14591 x86: remove more uaccess_32.h complexity
I'm looking at trying to possibly merge the 32-bit and 64-bit versions
of the x86 uaccess.h implementation, but first this needs to be cleaned
up.

For example, the 32-bit version of "__copy_from_user_inatomic()" is
mostly the special cases for the constant size, and it's actually almost
never relevant.  Most users aren't actually using a constant size
anyway, and the few cases that do small constant copies are better off
just using __get_user() instead.

So get rid of the unnecessary complexity.

The ndctl unit tests discovered that the dax enabling omitted updates to
nd_detach_and_reset().  This routine clears device the configuration
when the namespace is detached.  Without this clearing userspace may
assume that the device is in the process of being configured by another

Dan Williams 5e24c9fd36 libnvdimm, dax: fix alignment validation
Testing the dax-device autodetect support revealed a probe failure with
the following result:

    dax0.1: bad offset: 0x8200000 dax disabled

The original pfn-device implementation inferred the alignment from
ilog2(offset), now that the alignment is explicit the is_power_of_2()
needs replacing with a real sanity check against the recorded alignment.
Otherwise the alignment check is useless in the implicit case and only
the minimum size of the offset matters.

This self-consistency check is further validated by the probe path that
will re-check that the offset is large enough to contain all the
metadata required to enable the device.

Linus Torvalds 51e68d055c x86 isa: add back X86_32 dependency on CONFIG_ISA
Commit b3c1be1b78 ("base: isa: Remove X86_32 dependency") made ISA
support available on x86-64 too.  That's not right - while there are
some LPC-style devices that might be useful still and be based on
ISA-like IP blocks, that is *not* an excuse to try to enable any random
legacy drivers.

Such drivers should be individually enabled and made to perhaps depend
on ISA_DMA_API instead (which we have continued to support on x86-64).
Or we could add another "ISA_XYZ_API" that we support that doesn't
enable random old drivers that aren't even 64-bit clean nor do we have
any test coverage for.

Turning off ISA will now also turn off some drivers that have been
marked as depending on it as part of this series, and that used to work
on modern platforms.

See for example commits ad7afc38eab3..cc736607c86d, which may also need
to be reverted.

This commit means that the warnings that came in due to enabling ISA
widely are now gone again.

Dan Williams dee4107924 /dev/dax, core: file operations and dax-mmap
The "Device DAX" core enables dax mappings of performance / feature
differentiated memory.  An open mapping or file handle keeps the backing
struct device live, but new mappings are only possible while the device
is enabled.   Faults are handled under rcu_read_lock to synchronize
with the enabled state of the device.

Similar to the filesystem-dax case the backing memory may optionally
have struct page entries.  However, unlike fs-dax there is no support
for private mappings, or mappings that are not backed by media (see
use of zero-page in fs-dax).

Mappings are always guaranteed to match the alignment of the dax_region.
If the dax_region is configured to have a 2MB alignment, all mappings
are guaranteed to be backed by a pmd entry.  Contrast this determinism
with the fs-dax case where pmd mappings are opportunistic.  If userspace
attempts to force a misaligned mapping, the driver will fail the mmap
attempt.  See dax_dev_check_vma() for other scenarios that are rejected,
like MAP_PRIVATE mappings.

Dan Williams ab68f26221 /dev/dax, pmem: direct access to persistent memory
Device DAX is the device-centric analogue of Filesystem DAX
(CONFIG_FS_DAX).  It allows memory ranges to be allocated and mapped
without need of an intervening file system.  Device DAX is strict,
precise and predictable.  Specifically this interface:

1/ Guarantees fault granularity with respect to a given page size (pte,
pmd, or pud) set at configuration time.

2/ Enforces deterministic behavior by being strict about what fault
scenarios are supported.

For example, by forcing MADV_DONTFORK semantics and omitting MAP_PRIVATE
support device-dax guarantees that a mapping always behaves/performs the
same once established.  It is the "what you see is what you get" access
mechanism to differentiated memory vs filesystem DAX which has
filesystem specific implementation semantics.

Persistent memory is the first target, but the mechanism is also
targeted for exclusive allocations of performance differentiated memory
ranges.

This commit is limited to the base device driver infrastructure to
associate a dax device with pmem range.

Linus Torvalds 3aa2fc1667 driver core update for 4.7-rc1
Here's the "big" driver core update for 4.7-rc1.
 
 Mostly just debugfs changes, the long-known and messy races with removing
 debugfs files should be fixed thanks to the great work of Nicolai Stange.  We
 also have some isa updates in here (the x86 maintainers told me to take it
 through this tree), a new warning when we run out of dynamic char major
 numbers, and a few other assorted changes, details in the shortlog.
 
 All have been in linux-next for some time with no reported issues.

Linus Torvalds 0eff4589c3 It's the usual big pile of driver updates and additions, but we
do have a couple core changes in here as well.
 
 Core:
 
  - CLK_IS_CRITICAL support has been added. This should allow drivers
    to properly express that a certain clk should stay on even if
    their prepare/enable count drops to 0 (and in turn the parents of
    these clks should stay enabled).
 
  - A clk registration API has been added, clk_hw_register(), and
    an OF clk provider API has been added, of_clk_add_hw_provider().
    These APIs have been put in place to further split clk providers
    from clk consumers, with the goal being to have clk providers
    never deal with struct clk pointers at all. Conversion of provider
    drivers is on going. clkdev has also gained support for registering
    clk_hw pointers directly so we can convert drivers that don't use
    devicetree.
 
 New Drivers:
 
  - Marvell ap806 and cp110 system controllers (with clks inside!)
  - Hisilicon Hi3519 clock and reset controller
  - Axis ARTPEC-6 clock controllers
  - Oxford Semiconductor OXNAS clock controllers
  - AXS10X I2S PLL
  - Rockchip RK3399 clock and reset controller
 
 Updates:
 
  - MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos 542x
    SoCs, and some more clk ID exporting for bus frequency scaling
  - Proper BCM2835 PCM clk support and various other clks
  - i.MX clk updates for i.MX6SX, i.MX7, and VF610
  - Renesas updates for R-Car H3
  - Tegra210 got updates for DisplayPort and HDMI 2.0
  - Rockchip driver refactorings and fixes due to adding RK3399 support

Peter Zijlstra 54cf809b95 locking,qspinlock: Fix spin_is_locked() and spin_unlock_wait()
Similar to commits:

  51d7d5205d ("powerpc: Add smp_mb() to arch_spin_is_locked()")
  d86b8da04d ("arm64: spinlock: serialise spin_unlock_wait against concurrent lockers")

qspinlock suffers from the fact that the _Q_LOCKED_VAL store is
unordered inside the ACQUIRE of the lock.

And while this is not a problem for the regular mutual exclusive
critical section usage of spinlocks, it breaks creative locking like:

	spin_lock(A)			spin_lock(B)
	spin_unlock_wait(B)		if (!spin_is_locked(A))
	do_something()			  do_something()

In that both CPUs can end up running do_something at the same time,
because our _Q_LOCKED_VAL store can drop past the spin_unlock_wait()
spin_is_locked() loads (even on x86!!).

To avoid making the normal case slower, add smp_mb()s to the less used
spin_unlock_wait() / spin_is_locked() side of things to avoid this
problem.

During hugepage map/unmap, TSB and TLB flushes are currently
issued at every PAGE_SIZE'd boundary which is unnecessary.
We now issue the flush at REAL_HPAGE_SIZE boundaries only.

Without this patch workloads which unmap a large hugepage
backed VMA region get CPU lockups due to excessive TLB
flush calls.
