entry and tables.

Change table chaining layout

2007-10-22T19:20:01+00:00

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.

forbid asm/bitops.h direct inclusion

2007-10-19T18:53:41+00:00

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.

traces of it from all archs.

Remove dma_cache_(wback|inv|wback_inv) functions

2007-10-17T15:42:57+00:00

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.

remove include/asm-*/ipc.h

2007-10-17T15:42:55+00:00

All asm/ipc.h files do only #include .

This patch therefore removes all include/asm-*/ipc.h files and moves the
contents of include/asm-generic/ipc.h to include/linux/ipc.h.

remove strict ansi check from __u64 in asm/types.h

2007-10-17T15:42:53+00:00

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;
#endif

The __extension__ keyword in front of this switches off any pedantic
warnings for this expression.
