b590bc5cd0 Orion: move I/O macros out of orion.h
Move the Orion register accessor macros out of orion.h, to prevent
them from ending up in the decompressor image (Orion uncompress.h
includes orion.h.)  Move them into io.h, which seems a better place

98f79d1ea0 Orion: revamp cpu mbus window handling
Instead of forcing all device bus window setup through one function
with some enum as the first argument, create separate window setup
functions for each of the four possible targets, and do the demux
internally.  This allows getting rid of the window identifier enum
and the big switch statement in orion_setup_cpu_win().

2e8fe719b5 xen: fix UP setup of shared_info
We need to set up the shared_info pointer once we've mapped the real
shared_info into its fixmap slot.  That needs to happen once the general
pagetable setup has been done.  Previously, the UP shared_info was set
up one in xen_start_kernel, but that was left pointing to the dummy
shared info.  Unfortunately there's no really good place to do a later
setup of the shared_info in UP, so just do it once the pagetable setup
has been done.

04c44a080d xen: fix RMW when unmasking events
xen_irq_enable_direct and xen_sysexit were using "andw $0x00ff,
XEN_vcpu_info_pending(vcpu)" to unmask events and test for pending ones
in one instuction.

Unfortunately, the pending flag must be modified with a locked operation
since it can be set by another CPU, and the unlocked form of this
operation was causing the pending flag to get lost, allowing the processor
to return to usermode with pending events and ultimately deadlock.

The simple fix would be to make it a locked operation, but that's rather
costly and unnecessary.  The fix here is to split the mask-clearing and
pending-testing into two instructions; the interrupt window between
them is of no concern because either way pending or new events will
be processed.

This should fix lingering bugs in using direct vcpu structure access too.

d546b67a94 x86: fix performance drop for glx
fix the 3D performance drop reported at:

   http://bugzilla.kernel.org/show_bug.cgi?id=10328

fb drivers are using ioremap()/ioremap_nocache(), followed by mtrr_add with
WC attribute. Recent changes in page attribute code made both
ioremap()/ioremap_nocache() mappings as UC (instead of previous UC-). This
breaks the graphics performance, as the effective memory type is UC instead
of expected WC.

The correct way to fix this is to add ioremap_wc() (which uses UC- in the
absence of PAT kernel support and WC with PAT) and change all the
fb drivers to use this new ioremap_wc() API.

We can take this correct and longer route for post 2.6.25. For now,
revert back to the UC- behavior for ioremap/ioremap_nocache.

22b619eee5 [POWERPC] 85xx: Emerson KSI8560 base support
The KSI8560 is a single compact, mid-, or full-size Advanced Mezzanine Card
(AdvancedMC™) based on the Freescale™ Semiconductor MPC8560 PowerQUICC III™
microprocessor. This product will serve in data and signaling applications such
as signaling gateways (SGW) and softswitch signaling interface cards.

The board has altera maxii CPLD, that is used to obtain and manage board
configuration. Also there are two SCC UART serial consoles and FCC ethernet,
that is routed to the front panel, while other ethernet controlers (TSEC's) are
routed to the backplane.

2a7069190e [POWERPC] 4xx: Add PPC4xx L2-cache support (440GX)
This patch adds support for the 256k L2 cache found on some IBM/AMCC
4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c)
which currently "only" adds the L2 cache init code. Other common 4xx
stuff can be added later here.

The L2 cache handling code is a copy of Eugene's code in arch/ppc
with small modifications.

Tested on AMCC Taishan 440GX.

145692a734 [POWERPC] 4xx: Add "amcc, haleakala" to the toplevel compatible property
Currently Haleakala uses the Kilauea platform code. This patch adds
"haleakala" to the compatible property, in case later kernel versions
will introduce a Haleakala platform code.

c06cf7dad6 [POWERPC] 4xx: Add AMCC Glacier 460GT eval board dts
The patch adds the Glacier dts. The Glacier is nearly identical to the
Canyonlands (460EX). Here the differences:

- 4 ethernet ports instead of 2
- no SATA port
- no USB port

7831426351 [POWERPC] 4xx: Add TAH support to taishan dts
This patch adds TAH (TCP/IP Acceleration Hardware) support to the
taishan 440GX dts. It depends on the NEWEMAC/tah patch that adds the
compatible "ibm,tah" property to the matching table.

ed70854a4f [POWERPC] 4xx: Add platform support for the AMCC Yosemite board
The AMCC 440EP Yosemite board is very similar to the original AMCC Bamboo
board.  This adds a YOSEMITE option to Kconfig, and reuses the existing
bamboo board support in the kernel.
