Harald Freudenberger 3d8f60d38e s390/zcrypt: hex string mask improvements for apmask and aqmask.
The sysfs attributes /sys/bus/ap/apmask and /sys/bus/ap/aqmask
and the kernel command line arguments ap.apm and ap.aqm get
an improvement of the value parsing with this patch:

The mask values are bitmaps in big endian order starting with bit 0.
So adapter number 0 is the leftmost bit, mask is 0x8000... The sysfs
attributes and the kernel command line accept 2 different formats:
 - Absolute hex string starting with 0x like "0x12345678" does set
   the mask starting from left to right. If the given string is shorter
   than the mask it is padded with 0s on the right. If the string is
   longer than the mask an error comes back (EINVAL).
 - Relative format - a concatenation (done with ',') of the terms
   +<bitnr>[-<bitnr>] or -<bitnr>[-<bitnr>]. <bitnr> may be any
   valid number (hex, decimal or octal) in the range 0...255.
   Here are some examples:
     "+0-15,+32,-128,-0xFF"
     "-0-255,+1-16,+0x128"

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.
