2c6d0ee300 staging:rtl8192u: Refactor struct HT_CAPABILITY_ELE - Style
The structure HT_CAPABILITY_ELE causes a number of checkpatch / coding
style issues. The structure uses a 'typedef' directive causing an
issue regarding defining new types in the code. The name of the
structure should be lowercase, and the '__packed' directive is prefered
over the attribute directive.

The typedef has been removed, structure renamed to ht_capability_ele
and the '__packed' directive used.

These are coding style changes and should not impact on runtime code
execution.

9ff6cdd393 staging:rtl8192u: Remove enum CHNLOP - Style
The enumerated type CHNLOP is only used as a member variable of the
structure RT_HIGH_THROUGHPUT. Whilst this member variable is initialised
it is never actually used in the code. To simplify the code both the
enumerated type and the member variable have been removed.

This is a coding style change which should have no impact on runtime
code execution.

ccedf8912c staging:rtl8192u: Removed commented out structure - Style
Two unions HT_CAPABILITY and HT_CAPABILITY_MACPARA have previously been
commented out of code. Since they are obviously not used in code and
the commented out unions add nothing to the code they have been removed.

This is a coding style change which should have no impact on runtime
code execution.

3f119c9da3 staging:rtl8192u: Rename sHTCLng - Style
The constant sHTCLng causes a checkpatch issue, due to its use of
CamelCase naming. To correct the issue the constant has been renamed
to HTCLNG.

I'm not sure this is a good name as it communicates very little and
contradicts the block comment above its definition. MCS_LEN might
be a better name if the block comment is correct.

Additionally the block comment has been changed to the recommended
style.

This is a coding style change which should have no impact on runtime
code execution.

ace3c2a23c staging:rtl8192u: Remove macro cpMacAddr - Style
The macro cpMacAddr implements the same functionality as the
ether_addr_copy function defined in etherdevice.h, as a result the
macro has been removed from the code, and its use replaced with the

Note that the header comment of the function ether_addr_copy states
that the two byte arrays passed as parameters to the function must
be u16 aligned. Because of this the structure ieee80211_network has
had its member variables re-ordered so that the members bssid and
MBssid are aligned to a u16 boundary.

Merge tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm memory-failure update from Dave Jiang:
 "As it stands, memory_failure() gets thoroughly confused by dev_pagemap
  backed mappings. The recovery code has specific enabling for several
  possible page states and needs new enabling to handle poison in dax
  mappings.

  In order to support reliable reverse mapping of user space addresses:

   1/ Add new locking in the memory_failure() rmap path to prevent races
      that would typically be handled by the page lock.

   2/ Since dev_pagemap pages are hidden from the page allocator and the
      "compound page" accounting machinery, add a mechanism to determine
      the size of the mapping that encompasses a given poisoned pfn.

   3/ Given pmem errors can be repaired, change the speculatively
      accessed poison protection, mce_unmap_kpfn(), to be reversible and
      otherwise allow ongoing access from the kernel.

  A side effect of this enabling is that MADV_HWPOISON becomes usable
  for dax mappings, however the primary motivation is to allow the
  system to survive userspace consumption of hardware-poison via dax.
  Specifically the current behavior is:

     mce: Uncorrected hardware memory error in user-access at af34214200
     {1}[Hardware Error]: It has been corrected by h/w and requires no further action
     mce: [Hardware Error]: Machine check events logged
     {1}[Hardware Error]: event severity: corrected
     Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users
     [..]
     Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed
     mce: Memory error not recovered
     <reboot>

  ...and with these changes:

     Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000
     Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption
     Memory failure: 0x20cb00: recovery action for dax page: Recovered

  Given all the cross dependencies I propose taking this through
  nvdimm.git with acks from Naoya, x86/core, x86/RAS, and of course dax
  folks"

1b2de5d039 mm/cow: don't bother write protecting already write-protected pages
This is not normally noticeable, but repeated forks are unnecessarily
expensive because they repeatedly dirty the parent page tables during
the page table copy operation.

It's trivial to just avoid write protecting the page table entry if it
was already not writable.

This patch was inspired by

    https://bugzilla.kernel.org/show_bug.cgi?id=200447

which points to an ancient "waste time re-doing fork" issue in the
presence of lots of signals.

That bug was fixed by Eric Biederman's signal handling series
culminating in commit c3ad2c3b02 ("signal: Don't restart fork when
signals come in"), but the unnecessary work for repeated forks is still
work just fixing, particularly since the fix is trivial.

e0fcfe1f1a hpfs: remove unnecessary checks on the value of r when assigning error code
At the point where r is being checked for different values, r is always
going to be equal to 2 as the previous if statements jump to end or end1
if r is not 2.  Hence the assignment to err can be simplified to just
err an assignment without any checks on the value or r.

Thanks for your work in this area. I still remember the first linux
storage summit we did in Vancouver 2001, Tejun was invited to talk about
his libata error handling work. Before that, it was basically a crap
shoot if we recovered properly or not... A lot of water has flown under
the bridge since then!

Here's an "official" patch. Linus, can you apply it?
