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

commit f1befe71fa introduced a

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.

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.

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.

PAGE_SIZE means we flush too much, and if the page after the table

Some odd systems may have multiple BMCs, and we want to be able to support
them. Let's make the assumption that if a system legitimately has
multiple BMCs then each BMC's SI will be of the same type, and also that
we won't see multiple SIs of the same type unless we have multiple BMCs.
If these hold true then we should register all SIs of the same type.

drivers/char/hangcheck-timer.c is doubly broken. When the overflown value
of TIMER_FREQ is abnormally low, it spams the syslog with KERN_CRIT
messages "Hangcheck: hangcheck value past margin!" But whether it happens
or not depends on HZ and lpj in a complex way. People have hit it
occasionally as far as google search can tell.
First, the following line overflows unsigned long:
# define TIMER_FREQ (HZ*loops_per_jiffy)
Second, and more importantly, loops_per_jiffy has little to do with the
con= version from the the time scale of get_cycles() (aka rdtsc) to the
time scale of jiffies.
The attached patch resolves both of the problems.

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.
