Joerg Roedel 966396d3a0 x86 gart: rename CONFIG_IOMMU to CONFIG_GART_IOMMU
This patch renames the IOMMU config option to GART_IOMMU because in fact it
means the GART and not general support for an IOMMU on x86.

H. Peter Anvin 6619a8fb59 x86: Create clflush() inline, remove hardcoded wbinvd
Create an inline function for clflush(), with the proper arguments,
and use it instead of hard-coding the instruction.

This also removes one instance of hard-coded wbinvd, based on a patch
by Bauder de Oliveira Costa.

Fengguang Wu e57aa839ce convert ill defined log2() to ilog2()
It's *wrong* to have
			#define log2(n) ffz(~(n))
It should be *reversed*:
			#define log2(n) flz(~(n))
or
			#define log2(n) fls(n)
or just use
			ilog2(n) defined in linux/log2.h.

This patch follows the last solution, recommended by Andrew Morton.

Jesper Juhl bdc3e603cd fix use after free in amd create gatt pages
Coverity spotted a "use after free" bug in
drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages().

The problem is this:
	If "entry = kzalloc(sizeof(struct amd_page_map), GFP_KERNEL);"
fails, then there's a loop in the function to free all entries
allocated so far and break out of the allocation loop. That in itself
is pretty sane, but then the (now freed) 'tables' is assigned to
amd_irongate_private.gatt_pages and 'retval' is set to -ENOMEM which
causes amd_free_gatt_pages(); to be called at the end of the function.
The problem with this is that amd_free_gatt_pages() will then loop
'amd_irongate_private.num_tables' times and try to free each entry in
tables[] - this is bad since tables has already been freed and
furthermore it will call kfree(tables) at the end - a double free.

This patch removes the freeing loop in amd_create_gatt_pages() and
instead relies entirely on the call to amd_free_gatt_pages() to free
everything we allocated in case of an error. It also sets
amd_irongate_private.num_tables to the actual number of entries
allocated instead of just using the value passed in from the caller -
this ensures that amd_free_gatt_pages() will only attempt to free
stuff that was actually allocated.

Dave Airlie a2721e998e AGP fix race condition between unmapping and freeing pages
With Andi's clflush fixup, we were getting hangs on server exit, flushing the
mappings after freeing each page helped.

This showed up a race condition where the pages after being freed could be
reused before the agp mappings had been flushed.  Flushing after each single
page is a bad thing for future drm work, so make the page destroy a two pass
unmapping all the pages, flushing the mappings, and then destroying the pages.

Alexey Dobriyan 4e950f6f01 Remove fs.h from mm.h
Remove fs.h from mm.h. For this,
 1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
 2) Add back fs.h or less bloated headers (err.h) to files that need it.

As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
rebuilt down to 3444 (-12.3%).

Jesper Juhl 190644e180 Fix "use after free" / "double free" bug in ati_create_gatt_pages / ati_free_gatt_pages
Hi,

Coverity spotted a "use after free" bug in
drivers/char/agp/ati-agp.c::ati_create_gatt_pages().

The same one that was in
  drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages()

The problem is this:
       If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);"
fails, then there's a loop in the function to free all entries
allocated so far and break out of the allocation loop. That in itself
is pretty sane, but then the (now freed) 'tables' is assigned to
ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which
causes ati_free_gatt_pages(); to be called at the end of the function.
The problem with this is that ati_free_gatt_pages() will then loop
'ati_generic_private.num_tables' times and try to free each entry in
tables[] - this is bad since tables has already been freed and
furthermore it will call kfree(tables) at the end - a double free.

This patch removes the freeing loop in ati_create_gatt_pages() and
instead relies entirely on the call to ati_free_gatt_pages() to free
everything we allocated in case of an error. It also sets
ati_generic_private.num_tables to the actual number of entries
allocated instead of just using the value passed in from the caller -
this ensures that ati_free_gatt_pages() will only attempt to free
stuff that was actually allocated.

Note: I'm in no way intimate with this code and I have no way to
actually test this patch (besides compile test it), so while I've
tried to be careful in reading the code and make sure the patch
does the right thing an ACK from someone who actually knows the
code in-depth would be very much appreciated.

Auke Kok 44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

Alexey Dobriyan e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig
	ia64 ia64-up
	m68k
	mips
	parisc parisc-up
	powerpc powerpc-up
	s390 s390-up
	sparc sparc-up
	sparc64 sparc64-up
	um-x86_64
	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig

as well as my two usual configs.

Gabriel Mansi bbdfff86a8 [AGPGART] Fix wrong ID in via-agp.c
there is a wrong id in drivers/char/agp/via-agp.c
#define PCI_DEVICE_ID_VIA_CX700         0x8324
It must be 0x0324

Notice that PCI_DEVICE_ID_VIA_CX700 is also used in
drivers/i2c/busses/i2c-viapro.c and
drivers/ide/pci/via82cxxx.c

So, I think that constant must be renamed to avoid conflicting.

Oliver Neukum 82eab1306c [AGPGART] prevent probe collision of sis-agp and amd64_agp
For some vendor/id pairs the kernel will autoload both the sis-agp and the
amd64_agp modules as the sis-agp module will load for all sis devices.
This collision causes the bug reported in:
http://bugzilla.novell.com/show_bug.cgi?id=248665

As currently sis_probe does its own matching, requesting the whole range
gains nothing.  The clean fix seems to me to leave the matching to the core
and advertise only the devices actually supported.  This patch does so.
