[ Note, this is a Git cherry-pick of the following commit:

    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.

Pull rdma fixes from Jason Gunthorpe:
 "More fixes from testing done on the rc kernel, including more SELinux
  testing. Looking forward, lockdep found regression today in ipoib
  which is still being fixed.

  Summary:

   - Fix for SELinux on the umad SMI path. Some old hardware does not
     fill the PKey properly exposing another bug in the newer SELinux
     code.

   - Check the input port as we can exceed array bounds from this user
     supplied value

   - Users are unable to use the hash field support as they want due to
     incorrect checks on the field restrictions, correct that so the
     feature works as intended

   - User triggerable oops in the NETLINK_RDMA handler

   - cxgb4 driver fix for a bad interaction with CQ flushing in iser
     caused by patches in this merge window, and bad CQ flushing during
     normal close.

   - Unbalanced memalloc_noio in ipoib in an error path"
