sh: Fix occasional FPU register corruption under preempt.

2008-03-26T10:02:47+00:00

Presently with preempt enabled there's the possibility to be preempted
after the TIF_USEDFPU test and the register save, leading to bogus
state post-__switch_to(). Use an explicit preempt_disable()/enable()
pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86
change.

serial: Move asm-sh/sci.h to linux/serial_sci.h.

2008-02-26T05:52:45+00:00

This header is needed on other architectures as well (namely h8300),
which currently fails to build without this in place. Rather than
duplicating the port definition completely there, just move this to a
common location instead.

This should get h8300 working again for 2.6.25, in addition to the
changes already pushed by Sato-san in -rc2.

sh: Storage class should be before const qualifier

2008-02-26T05:04:17+00:00

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is an
obsolescent feature.

sh: intc - remove default interrupt priority tables

2008-01-28T04:19:02+00:00

This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.

The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

sh: Add SH7263 CPU support.

2008-01-28T04:18:57+00:00

This adds support for the SH7263 (SH-2A) CPU.

This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.

No visibly nasty surprises, yet..

sh: Use boot_cpu_data for CPU probe.

2007-09-27T09:18:39+00:00

This moves off of smp_processor_id() and only sets the probe
information for the boot CPU directly. This will be copied out
for the secondaries, so there's no reason to do this each time.

This also allows for some header tidying.

sh: intc - add support for sh7206

2007-09-21T02:57:50+00:00

This patch converts the cpu specific interrupt setup code for sh7206
from ipr to intc. New vectors are also added to match the information
provided by the datasheet.

sh: fix irqs for the second serial port on sh7206

2007-09-21T02:57:50+00:00

This patch makes sure the serial port interrupt irqs matches the
datasheet.  Only irqs for SCIF1 are changed. While at some cosmetic
spaces are added.
