    d17a1d97: ("x86/mm/kasan: don't use vmemmap_populate() to initialize shadow")

  ... for easier x86 PTI code testing and back-porting. ]

The KASAN shadow is currently mapped using vmemmap_populate() since that
provides a semi-convenient way to map pages into init_top_pgt.  However,
since that no longer zeroes the mapped pages, it is not suitable for
KASAN, which requires zeroed shadow memory.

Add kasan_populate_shadow() interface and use it instead of
vmemmap_populate().  Besides, this allows us to take advantage of
gigantic pages and use them to populate the shadow, which should save us
some memory wasted on page tables and reduce TLB pressure.

Currently free running PEBS is disabled when user or interrupt
registers are requested. Most of the registers are actually
available in the PEBS record and can be supported.

So we just need to check for the supported registers and then
allow it: it is all except for the segment register.

For user registers this only works when the counter is limited
to ring 3 only, so this also needs to be checked.

User-Mode Instruction Prevention is a security feature present in new
Intel processors that, when set, prevents the execution of a subset of
instructions if such instructions are executed in user mode (CPL > 0).
Attempting to execute such instructions causes a general protection
exception.

The subset of instructions comprises:

 * SGDT - Store Global Descriptor Table
 * SIDT - Store Interrupt Descriptor Table
 * SLDT - Store Local Descriptor Table
 * SMSW - Store Machine Status Word
 * STR  - Store Task Register

This feature is also added to the list of disabled-features to allow
a cleaner handling of build-time configuration.

This reverts commits 5c9d2d5c, c7da82b8, and e7fe7b5c.

We'll probably need to revisit this, but basically we should not
complicate the get_user_pages_fast() case, and checking the actual page
table protection key bits will require more care anyway, since the
protection keys depend on the exact state of the VM in question.

Particularly when doing a "remote" page lookup (ie in somebody elses VM,
not your own), you need to be much more careful than this was.  Dave
Hansen says:

 "So, the underlying bug here is that we now a get_user_pages_remote()
  and then go ahead and do the p*_access_permitted() checks against the
  current PKRU. This was introduced recently with the addition of the
  new p??_access_permitted() calls.

  We have checks in the VMA path for the "remote" gups and we avoid
  consulting PKRU for them. This got missed in the pkeys selftests
  because I did a ptrace read, but not a *write*. I also didn't
  explicitly test it against something where a COW needed to be done"

It's also not entirely clear that it makes sense to check the protection
key bits at this level at all.  But one possible eventual solution is to
make the get_user_pages_fast() case just abort if it sees protection key
bits set, which makes us fall back to the regular get_user_pages() case,
which then has a vma and can do the check there if we want to.

We'll see.

Somewhat related to this all: what we _do_ want to do some day is to
check the PAGE_USER bit - it should obviously always be set for user
pages, but it would be a good check to have back.  Because we have no
generic way to test for it, we lost it as part of moving over from the
architecture-specific x86 GUP implementation to the generic one in
commit e585513b ("x86/mm/gup: Switch GUP to the generic
get_user_page_fast() implementation").

Pull staging fixes from Greg KH:
 "Here are some small staging driver fixes for 4.15-rc4.

  One patch for the ccree driver to prevent an unitialized value from
  being returned to a caller, and the other fixes a logic error in the
  pi433 driver"

Pull device mapper fixes from Mike Snitzer:

 - fix a particularly nasty DM core bug in a 4.15 refcount_t conversion.

 - fix various targets to dm_register_target after module __init
   resources created; otherwise racing lvm2 commands could result in a
   NULL pointer during initialization of associated DM kernel module.

 - fix regression in bio-based DM multipath queue_if_no_path handling.

 - fix DM bufio's shrinker to reclaim more than one buffer per scan.

Pull SCSI fixes from James Bottomley:
 "The most important one is the bfa fix because it's easy to oops the
  kernel with this driver (this includes the commit that corrects the
  compiler warning in the original), a regression in the new timespec
  conversion in aacraid and a regression in the Fibre Channel ELS
  handling patch.

  The other three are a theoretical problem with termination in the
  vendor/host matching code and a use after free in lpfc.

  The additional patches are a fix for an I/O hang in the mq code under
  certain circumstances and a rare oops in some debugging code"

Pull overlayfs fixes from Miklos Szeredi:

 - fix incomplete syncing of filesystem

 - fix regression in readdir on ovl over 9p

 - only follow redirects when needed

 - misc fixes and cleanups

* 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:
  ovl: fix overlay: warning prefix
  ovl: Use PTR_ERR_OR_ZERO()
  ovl: Sync upper dirty data when syncing overlayfs
  ovl: update ctx->pos on impure dir iteration
  ovl: Pass ovl_get_nlink() parameters in right order
  ovl: don't follow redirects if redirect_dir=off

Currently mdio read/write takes around ~115us as the timeout
between status check is set to 100us.
By reducing the timeout to 1us mdio read/write takes ~15us to
complete. This improves the link up event response.
