sh: Revert __xdiv64_32 size change.

2007-07-13T03:27:13+00:00

It's only __div64_32 that needs the fix, __xdiv64_32 behaves as
expected with the original size.

sh: Correct __xdiv64_32/div64_32 return value size.

2007-07-06T01:58:04+00:00

These should be returning a uint32_t, whereas they were erroneously
returning a u64 before. As the register sizes are 32-bits, this doesn't
really make a lot of sense.

sh: Fixup ndelay() xloops calculation for alternate HZ.

2007-05-09T01:35:02+00:00

Currently the xloops calculation in ndelay() gets set to 0 when
calculated with HZ=250, fix up how we do the HZ factoring in order
to get this right for differing values.

sh: Kill off udivdi3 div64_32 wrapping.

2007-05-07T02:11:55+00:00

Previously we've been handling udivdi3 references and wrapping
them in to div64_32() automatically. This doesn't get a lot of
use, however, and as akpm noted in the recent thread on l-k:

	http://lkml.org/lkml/2007/2/27/241

we're better off simply ripping it out and going the do_div()
route if there happen to be any places that need it.

sh: Fix TCP payload csum bug in csum_partial_copy_generic().

2006-09-27T05:46:24+00:00

There's a bug in the Hitachi SuperH csum_partial_copy_generic()
implementation.  If the supplied length is 1 (and several alignment
conditions are met), the function immediately branches to label 4.
However, the assembly at label 4 expects the length to be stored in
register r2.  Since this has not occurred, subsequent behavior is
undefined.

This can cause bad payload checksums in TCP connections.

I've fixed the problem by initializing register r2 prior to the branch
instruction.

[PATCH] smp_processor_id() cleanup

2005-06-22T01:46:13+00:00

This patch implements a number of smp_processor_id() cleanup ideas that
Arjan van de Ven and I came up with.

The previous __smp_processor_id/_smp_processor_id/smp_processor_id API
spaghetti was hard to follow both on the implementational and on the
usage side.

Some of the complexity arose from picking wrong names, some of the
complexity comes from the fact that not all architectures defined
__smp_processor_id.

In the new code, there are two externally visible symbols:

 - smp_processor_id(): debug variant.

 - raw_smp_processor_id(): nondebug variant. Replaces all existing
   uses of _smp_processor_id() and __smp_processor_id(). Defined
   by every SMP architecture in include/asm-*/smp.h.

There is one new internal symbol, dependent on DEBUG_PREEMPT:

 - debug_smp_processor_id(): internal debug variant, mapped to
                             smp_processor_id().

Also, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new
lib/smp_processor_id.c file.  All related comments got updated and/or
clarified.

I have build/boot tested the following 8 .config combinations on x86:

 {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT}

I have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT.  (Other
architectures are untested, but should work just fine.)
