[ARM] 4410/1: Remove extern declarations in coyote/ixdpg425-pci.c

2007-05-30T12:15:39+00:00

This patch removes apparently unnecessary extern declarations in
coyote-pci.c and ixdpg425-pci.c within arch/arm/mach-ixp4xx and
has been compile-tested without producing warnings or errors.

Kernel coding style forbids the use of extern declarations within .c
files.

2007-05-30T12:15:23+00:00

The S3C2412 has an reset-errata where the clock
may cause a glitch switching back to EXTCLK. We
force a switch to EXTCLK before writing the
reset register to force use of the CLKCON sync
logic to properly switch.

[ARM] Fix stacktrace FP range checking

2007-05-30T12:15:12+00:00

Fix an oops in the stacktrace code, caused by improper range checking.
We subtract 12 off 'fp' before testing to see if it's below the low
bound.  However, if 'fp' were zero before, it becomes a very large
positive number, causing this test to succeed where it should fail.
