Jesse Barnes d1d6ca73ef drm/agp/i915: trim stolen space to 32M
Some BIOSes will claim a large chunk of stolen space.  Unless we
reclaim it, our aperture for remapping buffer objects will be
constrained.  So clamp the stolen space to 32M and ignore the rest.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15469 among others.

Adding the ignored stolen memory back into the general pool using the
memory hotplug code is left as an exercise for the reader.

Grant Likely 22ae782f86 of/address: Clean up function declarations
This patch moves the declaration of of_get_address(), of_get_pci_address(),
and of_pci_address_to_resource() out of arch code and into the common
linux/of_address header file.

This patch also fixes some of the asm/prom.h ordering issues.  It still
includes some header files that it ideally shouldn't be, but at least the
ordering is consistent now so that of_* overrides work.

Tim Gardner e7b96f28c5 agp/intel: Use the correct mask to detect i830 aperture size.
BugLink: https://bugs.launchpad.net/bugs/597075

commit f1befe71fa introduced a
regression when detecting aperture size of some i915 adapters, e.g.,
those on the Intel Q35 chipset.

The original report: https://bugzilla.kernel.org/show_bug.cgi?id=15733
The regression report: https://bugzilla.kernel.org/show_bug.cgi?id=16294

According to the specification found at
http://intellinuxgraphics.org/VOL_1_graphics_core.pdf, the PCI config
space register I830_GMCH_CTRL is a mirror of GMCH Graphics
Control. The correct macro for isolating the aperture size bits is
therefore I830_GMCH_GMS_MASK along with the attendant changes to the
case statement.

Both of_bus_type and of_platform_bus_type are just #define aliases

switches to the of_register_platform_driver()/of_unregister_platform_driver()

Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim.  At which
point the of_register_platform_driver()/of_unregister_platform_driver()

Chris Metcalf 4455b1191c hvc_console: use "*_console" nomenclature to avoid modpost warning.
The use of "hvc_con_driver" as the name for a file-static "struct
console" with a ".setup" field pointing to an __init function causes
a modpost warning, since a non-initdata structure points to init code.
Using "hvc_console" as the name triggers the hacky "*_console"
workaround in modpost to silence the warning, and is the same thing
that most of the other console drivers already do.

I made the same change in hvsi.c since I happened to notice it was
likely to suffer from the same problem.

The ipmi code will never register a PCI or Open Firmware driver if a
hardcoded device is provided by the user by providing device addresses via
the module parameters.  This can cause us to attempt to unregister a
driver that was never registered, resulting in an oops.  Keep track of
registration in order to avoid this.

Fixes a post-2.6.34 regression.

Rajiv Andrade 02a077c52e TPM: ReadPubEK output struct fix
This patch adds a missing element of the ReadPubEK command output,

Prevents a kernel panic in case the user tries to read the

Linus Torvalds 386f40c86d Revert "tty: fix a little bug in scrup, vt.c"
This reverts commit 962400e8fd, which was
entirely bogus.

The code used to multiply the character offset by "vc->vc_cols", and
that's actually correct, because 'd' itself is an 'unsigned short'.  So
the pointer arithmetic already takes the size of a VGA character into
account.  Changing it to use vc_size_row (which is just "vc_cols"
shifted up to take the size of the character into account) ends up
multiplying with the VGA character size twice.

This got reported as bugs for various other subsystems, because what it
actually results in is writing the 16-bit vc_video_erase_char pattern
(usually 0x0720: 0x07 is the default attribute, 0x20 is ASCII space)
into some random other allocation.

So Markus ended up reporting this as a ext4 bug, while to Torsten Kaiser
it looked like a problem with KMS or libata.  Jeff Chua saw it in
different places.

And finally - Justin Mattock had slab poisoning enabled, and saw it as a
slab poison overwritten.  And bisected and reverted this to verify the
buggy commit.

The code uses vc->vc_cols instead of vc->vc_size_row by mistake, it
will cause half of the region which is going to clear remain
uncleared.
The issue happens in background consoles, so it's hard to observe.

Paul Mackerras 79905ad50b agp/uninorth: Fix oops caused by flushing too much
This fixes a sporadic oops at boot on G5 Power Macs.  The table_end
variable has the address of the last byte of the table.  Adding on
PAGE_SIZE means we flush too much, and if the page after the table
is not mapped for any reason, the kernel will oops.  Instead we add
on 1 because flush_dcache_range() interprets its second argument as
the first byte past the range to be flushed.
