Russell King c5eae69257 ARM: net: bpf: improve 64-bit store implementation
Improve the 64-bit store implementation from:

  ldr     r6, [fp, #-8]
  str     r8, [r6]
  ldr     r6, [fp, #-8]
  mov     r7, #4
  add     r7, r6, r7
  str     r9, [r7]

to:

  ldr     r6, [fp, #-8]
  str     r8, [r6]
  str     r9, [r6, #4]

We leave the store as two separate STR instructions rather than using
STRD as the store may not be aligned, and STR can handle misalignment.

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.
