Chris Packham 8f05bcc33e hwmon: (adt7475) temperature smoothing
When enabled temperature smoothing allows ramping the fan speed over a
configurable period of time instead of jumping to the new speed
instantaneously.

Chris Packham 3490c92a09 hwmon: (adt7475) add high frequency support
Systems using 4-wire fans usually require high frequency (22.5kHz)
output on the pwm. Add 22500 as a valid option in the pwmfreq_table. In
high frequency mode the low-order bit are ignored so they can safely be
set to 0.

Chris Packham 1d58f5efbf hwmon: (adt7475) fan stall prevention
By default adt7475 will stop the fans (pwm duty cycle 0%) when the
temperature drops past Tmin - hysteresis. Some systems want to keep the
fans moving even when the temperature drops so add new sysfs attributes
that configure the enhanced acoustics min 1-3 which allows the fans to
run at the minimum configure pwm duty cycle.

Chris Packham e465164040 hwmon: (adt7475) replace find_nearest() with find_closest()
The adt7475 has had find_nearest() since it's creation in 2009. Since
then find_closest() has been introduced and several drivers have been
updated to use it. Update the adt7475 to use find_closest() and remove
the now unused find_nearest().

Guenter Roeck cc66b30382 hwmon: (nct6775) Rework temperature source and label handling
Instead of checking if a temperature source has a label, use a bit mask

   - Fix a potential NULL deref after error in x509_cert_parse().

   - Don't put data for the crypto algorithms to use on the stack.

   - Fix the handling of a null payload being passed to add_key().

   - Fix incorrect cleanup an uninitialised key_preparsed_payload in
     key_update().

   - Explicit sanitisation of potentially secure data before freeing.

Linus Torvalds 6d53cefb18 compiler, clang: properly override 'inline' for clang
Commit abb2ea7dfd ("compiler, clang: suppress warning for unused
static inline functions") just caused more warnings due to re-defining
the 'inline' macro.

So undef it before re-defining it, and also add the 'notrace' attribute
like the gcc version that this is overriding does.

Maybe this makes clang happier.

This is triggered by running both win7 and win2016 on L1 KVM simultaneously,
and then gives stress to memory on L1, I can observed this hang on L1 when
at least ~70% swap area is occupied on L0.

This is due to async pf was injected to L2 which should be injected to L1,
L2 guest starts receiving pagefault w/ bogus %cr2(apf token from the host
actually), and L1 guest starts accumulating tasks stuck in D state in
kvm_async_pf_task_wait() since missing PAGE_READY async_pfs.

This patch fixes the hang by doing async pf when executing L1 guest.

Merge tag 'drm-fixes-for-v4.12-rc5' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "Intel, nouveau, rockchip, vmwgfx, imx, meson, mediatek and core fixes.

  Bit more spread out fixes this time, fixes for 7 drivers + a couple of
  core fixes.

  i915 and vmwgfx are the main ones. The vmwgfx ones fix a bunch of
  regressions in their atomic rework, and a few fixes destined for
  stable. i915 has some 4.12 regressions and older things that need to
  be fixed in stable as well.

  nouveau also has some runtime pm fixes and a timer list handling fix,
  otherwise a couple of core and small driver regression fixes"

Al Viro babef37dcc excessive checks in ufs_write_failed() and ufs_evict_inode()
As it is, short copy in write() to append-only file will fail
to truncate the excessive allocated blocks.  As the matter of
fact, all checks in ufs_truncate_blocks() are either redundant
or wrong for that caller.  As for the only other caller
(ufs_evict_inode()), we only need the file type checks there.

Omar Sandoval 70e7af244f Btrfs: fix delalloc accounting leak caused by u32 overflow
btrfs_calc_trans_metadata_size() does an unsigned 32-bit multiplication,
which can overflow if num_items >= 4 GB / (nodesize * BTRFS_MAX_LEVEL * 2).
For a nodesize of 16kB, this overflow happens at 16k items. Usually,
num_items is a small constant passed to btrfs_start_transaction(), but
we also use btrfs_calc_trans_metadata_size() for metadata reservations
for extent items in btrfs_delalloc_{reserve,release}_metadata().

In drop_outstanding_extents(), num_items is calculated as
inode->reserved_extents - inode->outstanding_extents. The difference
between these two counters is usually small, but if many delalloc
extents are reserved and then the outstanding extents are merged in
btrfs_merge_extent_hook(), the difference can become large enough to
overflow in btrfs_calc_trans_metadata_size().

The overflow manifests itself as a leak of a multiple of 4 GB in
delalloc_block_rsv and the metadata bytes_may_use counter. This in turn
can cause early ENOSPC errors. Additionally, these WARN_ONs in
extent-tree.c will be hit when unmounting:

    WARN_ON(fs_info->delalloc_block_rsv.size > 0);
    WARN_ON(fs_info->delalloc_block_rsv.reserved > 0);
    WARN_ON(space_info->bytes_pinned > 0 ||
            space_info->bytes_reserved > 0 ||
            space_info->bytes_may_use > 0);

Fix it by casting nodesize to a u64 so that
btrfs_calc_trans_metadata_size() does a full 64-bit multiplication.
While we're here, do the same in btrfs_calc_trunc_metadata_size(); this
can't overflow with any existing uses, but it's better to be safe here
than have another hard-to-debug problem later on.

Liu Bo 452e62b71f Btrfs: clear EXTENT_DEFRAG bits in finish_ordered_io
Before this, we use 'filled' mode here, ie. if all range has been
filled with EXTENT_DEFRAG bits, get to clear it, but if the defrag
range joins the adjacent delalloc range, then we'll have EXTENT_DEFRAG
bits in extent_state until releasing this inode's pages, and that
prevents extent_data from being freed.

This clears the bit if any was found within the ordered extent.

Su Yue 286b92f43c btrfs: tree-log.c: Wrong printk information about namelen
In verify_dir_item, it wants to printk name_len of dir_item but
printk data_len acutally.

Fix it by calling btrfs_dir_name_len instead of btrfs_dir_data_len.
