kmemtrace now uses tracepoints instead of markers. We no longer need to
use format specifiers to pass arguments.

tracepoints
Impact: cleanup
linux/percpu.h includes linux/slab.h, which generates circular inclusion
dependencies when trying to switch kmemtrace to use tracepoints instead
of markers.
This patch allows tracing within slab headers' inline functions.

We want to remove percpu.h from rcupreempt.h, but if we do that
the percpu primitives there wont build anymore. Move them to the
.c file instead.

Impact: cleanup
We want to remove rcutree internals from the public rcutree.h file for
upcoming kmemtrace changes - but kernel/rcutree_trace.c depends on them.
Introduce kernel/rcutree.h for internal definitions. (Probably all
the other data types from include/linux/rcutree.h could be
moved here too - except rcu_data.)

Impact: build fix for all non-x86 architectures
We want to remove percpu.h from rcuclassic.h/rcutree.h (for upcoming
kmemtrace changes) but that would break the DECLARE_PER_CPU based
declarations in these files.
Move the quiescent counter management functions to their respective
RCU implementation .c files - they were slightly above the inlining
limit anyway.

Impact: cleanup
We want to remove percpu.h from rcupdate.h (for upcoming kmemtrace
changes), but this is not possible currently without breaking the
build because fs.h has an implicit include file depedency: it
uses PAGE_SIZE but does not include asm/page.h which defines it.
This problem gets masked in practice because most fs.h using sites
use rcupreempt.h (and other headers) which includes percpu.h which
brings in asm/page.h indirectly.
We cannot add asm/page.h to asm/fs.h because page.h is not an
exported header.
Move simple_transaction_set() to the other simple-transaction
file helpers in fs/libfs.c.
This removes the include file hell and also reduces
kernel size a bit.

linux/security.h
Impact: cleanup
We want to remove percpu.h from rcupdate.h (for upcoming kmemtrace
changes), but this is not possible currently without breaking the
build because fs.h has implicit include file depedencies: it uses
GFP_* types in inlines but does not include gfp.h.
In practice most fs.h using .c files get gfp.h included implicitly,
via an indirect route: via rcupdate.h inclusion - so this underlying
problem gets masked in practice.
So we want to solve fs.h's dependency on gfp.h.
gfp.h can not be included here directly because it is not exported and it
would break the build the following way:
/home/mingo/tip/usr/include/linux/bsg.h:11: found __[us]{8,16,32,64} type without #include <linux/types.h>
/home/mingo/tip/usr/include/linux/fs.h:11: included file 'linux/gfp.h' is not exported
make[3]: *** [/home/mingo/tip/usr/include/linux/.check] Error 1
make[2]: *** [linux] Error 2
As suggested by Alexey Dobriyan, move alloc_secdata() and free_secdata()
to linux/security.h - they belong there. This also cleans fs.h of GFP_*
usage.

The current logic for dmi matching in efifb does not allow efifb to load
on all hardware that we can dmi match for.
For a real world example, boot with elilo (3.7 or 3.8 vanilla) and on a
Apple (MacBook) and EFI framebuffer driver will not load (you will have no
video). This specific hardware is efi v1.10, so we have UGA and not GOP.
Without special bootloader magic (i.e. extra elilo patches for UGA
graphics detection) no screen info will be passed to the kernel and as a
result efifb will not load.
This patch allows the dmi match to happen by moving it to earlier in
efifb_init, and sets the video type (in set_system) so that efifb can load
when we have a valid dmi match and already know the specifics of the
hardware.
Without this patch the efifb driver will fail to load in the event screen
info is not found and passed in by the bootloader, being that we will
never get to look for a dmi match. A primary reason for matching with dmi
is because not all bootloaders detect the video info properly. The
solution is that in the event of a dmi match, we should set
screen_info.orig_video_isVGA. Most bootloaders fail to set screen info on
Apple hardware, and this is a big problem for people who use Apple
hardware.
Tested on a MacBook SantaRosa with elilo-3.8 (vanilla) and resolves the
issue, the dmi match now works, EFI framebuffer now loads and video works.

Remove Kconfig option for tridentfb acceleration. The acceleration can be
switched off with modules "noaccel" parameter.
The acceleration for Trident chips was fixed in the 2.6.27 kernel.
Also, add CyberXXX and CyberBlade names to Kconfig option's name. It should
make easier to find the tridentfb choice for cyblafb driver's users. The
cyblafb driver has been replaced by the tridentfb driver.

A hardware cursor is left enabled in the fb_set_par() which is called when a
new console is created. This is inconsistent with software cursor's
behaviour.
Also, this makes a hardware cursor always visible in the Xfbdev (Xorg kdrive)
server.

If the vbemode option is used, uvesafb calls fb_get_mode() without first
setting the resolution in info->var. This results in a division by zero
in fb_get_mode(), as evidenced e.g. in [1]. Fix this by ensuring the
info->var structure is populated before fb_get_mode() is called.

A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.
Changes to the tridentfb driver:
- FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter
for scrolling which is faster than color expansion on Cyberblade
chipsets. The blitter is slower on a discrete Blade3D core. Use the
blitter for scrolling in the tridentfb only for integrated Blade3D
cores. Now, scrolling speed is about equal for the tridentfb and the
cyblafb.
- a copyright notice addition is done on request of Jani Monoses (the
first author of the tridentfb).
Tested on AGP Blade3D card and PCChips
M787CLR motherboard: VIA C3 cpu +
VT8601 north bridge (aka Cyberblade/i1).

Add support for the newer Samsung devices, such as found in the S3C2443,
S3C6400 or S3C6410 series SoC.
It currently does not support all the alpha- or chroma-key options but it
will support more exporting more than one framebuffer ready for adding
overlay and blending functions.

The s1d13xxx chip provides two values of identification value: the
Production id (e.g 13506/13505/13806..) and a revision number 0,1,2,3).
Together these can help us to differentiate between similiar setups.
This patch adds the proper way of grabbing both those values and save them
for future reference (in order to decide what functions a card supports,
e.g acceleration).
We also move away from the concept of all s1d13xxx = s1d13806 when we
really support alot more.
