The patch
apci: fix PXB behaviour if used with unsupported BIOS
uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:
(!range_base || range_base > range_limit)
When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.
Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression
(range_base || range_base > range_limit)
leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.
The correct negative of the condition seen at the top is
(range_base && range_base <= range_limit)
Fix the expressions.

The ACPI specification permits the _HID and _UID objects to evaluate to
strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in
the ACPI v6.0 spec.)
With regard to related standards, the UEFI specification can also express
a device address composed from string _HID and _UID identifiers, inside
the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table
49, in the UEFI v2.5 spec.)
However, numeric (integer) contents for both _HID and _UID are more
traditional. They are recommended by the UEFI spec for size reasons:
[...] the ACPI Device Path node is smaller and should be used if
possible to reduce the size of device paths that may potentially be
stored in nonvolatile storage [...]
External tools support them better (for example the --acpi_hid and
--acpi_uid options of "efibootmgr" only take numeric identifiers).
Finally, numeric _HID and _UID contents are existing practice in the QEMU
source.
This patch was tested with a Fedora 20 LiveCD and a preexistent Windows
Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we
get, in the SSDT:
> Scope (\_SB)
> {
> Device (PC04)
> {
> Name (_UID, 0x04) // _UID: Unique ID
> Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID

Commit 94c2b6aff4 (mips_malta: support up to 2GiB RAM) provided
support for using over 256MB of RAM with the MIPS Malta board, including
capping the memsize variable that QEMUs pseudo-bootloader provides to
the kernel at 256MB in order to match YAMON. It didn't however provide
the ememsize variable which kernels supporting memory outside of the
unmapped address spaces (ie. EVA or highmem) may use to determine the
true size of the RAM present in the system.
Set ememsize to the size of RAM so that such kernels may use all
available memory without the user having to manually specifying its size
& location.
