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

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.

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.

After a reset of a QEMU -machine q35 guest, the PCI Express
Enhanced Configuration Mechanism is disabled and the variable
mmconfig no longer matches the configuration register PCIEXBAR
of the Q35 chipset. Until the variable mmconfig is reset to 0,
all pci_config_*() functions no longer work.
The variable mmconfig is located in one of the read-only C-F
segments. To reset it the pci_config_*() functions are needed,
but they do not work.
Replace all pci_config_*() calls with Standard PCI Configuration
Mechanism pci_ioconfig_*() calls until mmconfig is overwritten
with 0 by a fresh copy of the BIOS.
This fixes
In resume (status=0)
In 32bit resume
Attempting a hard reboot
Unable to unlock ram - bridge not found
and a reset loop with QEMU -accel tcg.

Subject: [PATCH] virtio-blk: use larger default request size
RH-Author: Gerd Hoffmann <kraxel@redhat.com>
RH-MergeRequest: 5: virtio-blk: use larger default request size
RH-Commit: [1/1] 5b2833de23fdab9fc3c170e448e9ed07d9fb82dd (kraxel/centos-seabios)
RH-Bugzilla: 2108555
RH-Acked-by: Oliver Steffen <osteffen@redhat.com>

Bump default from 8 to 64 blocks. Using 8 by default leads
to requests being splitted on qemu, which slows down boot.
Some (temporary) debug logging added showed that almost all
requests on a standard fedora install are less than 64 blocks,
so that should bring us back to 1.15 performance levels.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
(cherry picked from commit 46de2eec93bffa0706e6229c0da2919763c8eb04)
