O-Subject: [RHEL7.0 seabios PATCH] Workaround for a win8.1-32 S4 resume bug
Bugzilla: 1050775

brew: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=7176174
This patch has no upstream equivalent.
When a 32 bit version of windows 8.1 resumes from suspend, it writes 1
into 0x72 in the early boot because it didn't expect a NULL pointer.
0x72 is lower offset byte of 0x1c interrupt entry, so we jump into a
middle of other function if this interrupt is triggered.
Because 0x1c is only triggered from our handle_08, we detect if our
default value (function that does only iret) has its lower offset byte
overwritten and skip it in that case.
(Windows never sets own callback there, so we always detect this bug
correctly, as seabios doesn't use it either
Other sources shouldn't incorrectly overwrite it or use seabios code,
but it is quite ok even if the guest did this on purpose.)
The reason Windows uses NULL pointer is still unknown, but this bug is
blocking WHQL certification, so we have to work around it in 7.0.

===================
seabios development
===================
seabios is maintained in a `source tree`_ rather than directly in dist-git
using packit service that provides way to develope using regular source code
structure and provides way to generate SRPM and build using koji service.
Developers deliver all changes to source-git using merge request. Only maintainers
will be pushing changes sent to source-git to dist-git.
Each release in dist-git is tagged in the source repository so you can easily
check out the source tree for a build. The tags are in the format
name-version-release, but note release doesn't contain the dist tag since the
source can be built in different build roots (Fedora, CentOS, etc.)
.. _source tree: https://gitlab.com/redhat/centos-stream/src/seabios

Use the variable highram_size instead of the BUILD_MAX_HIGHTABLE #define
for the ZoneHigh size. Initialize the new variable with the old #define,
so behavior does not change.
This allows to easily adjust the ZoneHigh size at runtime in a followup
patch.
