Add a Kconfig entry which will toggle some sanity checks on the sg
entry and tables.Signed-off-by: Jens Axboe

Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
NULL when passed such an entry.It's thus important that sg table users use the proper accessors to get
and set the page member.Signed-off-by: Jens Axboe

forbid asm/bitops.h direct inclusion
Because of compile errors that may occur after bit changes if asm/bitops.h is
included directly without e.g. linux/kernel.h which includes linux/bitops.h,
forbid direct inclusion of asm/bitops.h. Thanks to Adrian Bunk.Signed-off-by: Jiri Slaby

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes. Originally it was basically the raw
MIPS low level cache API exported to the entire world. The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync. So
remove it rsp. turn the surviving bits back into an arch private API, as
discussed on linux-arch.Signed-off-by: Ralf Baechle

Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
32bit targets.GCC can be made to warn about usage of long long types with ISO C90
(-ansi), but only with -pedantic. You can write this in a way that even
then it doesn't cause warnings, namely by:#ifdef __GNUC__
__extension__ typedef __signed__ long long __s64;
__extension__ typedef unsigned long long __u64;
#endifThe __extension__ keyword in front of this switches off any pedantic
warnings for this expression.Signed-off-by: Olaf Hering

I'm not sure if this is going to fly, weak symbols work on the compilers I'm
using, but whether they work for all of the affected architectures I can't say.
I've cc'ed as many arch maintainers/lists as I could find.But assuming they do, we can use a weak empty definition of
pcibios_add_platform_entries() to avoid having an empty definition on every
arch.Signed-off-by: Michael Ellerman

This finally renames the thread_info field in task structure to stack, so that
the assumptions about this field are gone and archs have more freedom about
placing the thread_info structure.Nonbroken archs which have a proper thread pointer can do the access to both
current thread and task structure via a single pointer.It'll allow for a few more cleanups of the fork code, from which e.g. ia64
could benefit.Signed-off-by: Roman Zippel
