Peter Zijlstra 52a288c736 x86/mm/tlb: Revert the recent lazy TLB patches 
Revert commits:

  95b0e6357d x86/mm/tlb: Always use lazy TLB mode
  64482aafe5 x86/mm/tlb: Only send page table free TLB flush to lazy TLB CPUs
  ac03158969 x86/mm/tlb: Make lazy TLB mode lazier
  61d0beb579 x86/mm/tlb: Restructure switch_mm_irqs_off()
  2ff6ddf19c x86/mm/tlb: Leave lazy TLB mode at page table free time

In order to simplify the TLB invalidate fixes for x86 and unify the
parts that need backporting.  We'll try again later.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
