Uros Bizjak dfd57c6210 x86/vdso: Fix output operand size of RDPID
[ Upstream commit ac9c408ed19d535289ca59200dd6a44a6a2d6036 ]

RDPID instruction outputs to a word-sized register (64-bit on x86_64 and
32-bit on x86_32). Use an unsigned long variable to store the correct size.

LSL outputs to 32-bit register, use %k operand prefix to always print the
32-bit name of the register.

Use RDPID insn mnemonic while at it as the minimum binutils version of
2.30 supports it.

  [ bp: Merge two patches touching the same function into a single one. ]

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.

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.
