sh: Add support for 4K stacks.

2006-09-27T09:22:14+00:00

This enables support for 4K stacks on SH.

Currently this depends on DEBUG_KERNEL, but likely all boards
will switch to this as the default in the future.

sh: Fixup __strnlen_user() behaviour.

2006-09-27T08:07:07+00:00

Drop TIF_USERSPACE and add addr_limit to the thread_info struct.
Subsequently, use that for address checking in strnlen_user() to
ward off bogus -EFAULTs.

Make __strnlen_user() return 0 on exception, rather than -EFAULT.

2006-09-27T07:01:12+00:00

Initial register bank cleanup. Make SR.RB configurable, and add some
preliminary documentation on register bank usage within the kernel.

[PATCH] bitops: sh: make thread_info.flags an unsigned long

2006-03-26T16:57:15+00:00

The test_bit() routines are defined to work on a pointer to unsigned long.
But thread_info.flags is __u32 (unsigned int) on sh and it is passed to flag
set/clear/test wrappers in include/linux/thread_info.h.  So the compiler will
print warnings.

This patch changes to unsigned long instead.

[PATCH] streamline preempt_count type across archs

2005-06-23T16:45:19+00:00

The preempt_count member of struct thread_info is currently either defined
as int, unsigned int or __s32 depending on arch.  This patch makes the type
of preempt_count an int on all archs.

Having preempt_count be an unsigned type prevents the catching of
preempt_count < 0 bugs, and using int on some archs and __s32 on others is
not exactely "neat" - much nicer when it's just int all over.

A previous version of this patch was already ACK'ed by Robert Love, and the
only change in this version of the patch compared to the one he ACK'ed is
that this one also makes sure the preempt_count member is consistently
commented.

[PATCH] sh: PREEMPT_ACTIVE fix

2005-05-28T23:46:13+00:00

Port Paulus's ppc64 fix to sh:

  When the generic IRQ stuff went in, it seems that HARDIRQ_BITS got bumped
  from 9 (for ppc64) up to 12.  Consequently, the PREEMPT_ACTIVE bit is now
  within HARDIRQ_MASK, and I get in_interrupt() falsely returning true when
  PREEMPT_ACTIVE is set, and thus a BUG_ON tripping in arch/ppc64/mm/tlb.c.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
