When I run a preemptive kernel-2.6.20 for SH7780, a created
kthread(pdflush) can not exit by do_exit() in kernel_thread_helper. I
think that the created kthread should have a room for 'struct pt_regs'
space on the stack top, because __switch_to() will refer to the space as
follows using 'regs = task_pt_regs(prev)' and next condition may be true.

This takes care of tearing down the UBC so it's not inadvertently
left configured at the next context switch time. Failure to do
this results in spurious SIGTRAPs in certain debug sequences.

An off-by-one bug meant we were always trying to map one too many
scatterlist entries.  This was mostly harmless prior to the checks
going in to consistent_sync(), but now causes the kernel to BUG.

Also, powertec.c was missing an assignment to info->ec.

SCSI doesn't want drivers to modify request_bufflen, so keep a

Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Replace the I2C bus address, as per drivers/acorn/char/pcf8583.c.

Also, since this driver also contains Acorn RiscPC specific code
for obtaining the current year from the SRAM (and updating the
platform specific checksum when writing new data back) this is
NOT a platform independent driver.

Document it as such, and update the dependencies to reflect this
fact.

Both BCD_TO_BIN(x) and BIN_TO_BCD(x) have an unexpected side-effect -

A bogus 'return r' can cause an otherwise successful module load to fail.
This both denies users the use of kvm, and it also denies them the use of
their machine, as it leaves a filesystem registered with its callbacks
pointing into now-freed module memory.

Fix by returning a zero like a good module.

the problem and for providing access to a machine which exhibited it.
