Kyle McMartin ef1afd4d79 [PARISC] pdc_console: fix bizarre panic on boot
Commit 721fdf3416 introduced a subtle bug
by accidently removing the "static" from iodc_dbuf. This resulted in, what
appeared to be, a trap without *current set to a task. Probably the result of
a trap in real mode while calling firmware.

Also do other misc clean ups. Since the only input from firmware is non
blocking, share iodc_dbuf between input and output, and spinlock the
only callers.

Kyle McMartin 721fdf3416 [PARISC] print more than one character at a time for pdc console
There's really no reason not to print more than one character at a
time to the PDC console... Booting is measurably speedier, and now I don't
have to watch individual characters get drawn.

Kyle McMartin 218c998caa [PARISC] Clean up asm-parisc/pdc.h
If we're going to export the header, at least let's organize it sensibly and
not have a mishmash of userspace, assembly, and kernel visible defines.

Kyle McMartin ec1fdc24c2 [PARISC] OS_ID_LINUX == 0x0006
We were assigned an OS_ID of 0x0006. Consistently use OS_ID_LINUX
instead of using the magic number. Also update the OS_ID_ defines in
asm/pdc.h to reflect this.

Kyle McMartin a9d2d386c4 [PARISC] Ensure Space ID hashing is turned off
Check PDC_CACHE to see if spaceid hashing is turned on, and fail to
boot if that is the case.

However, some old machines do not implement the PDC_CACHE_RET_SPID
firmware call, so continue to boot if the call fails because of
PDC_BAD_OPTION (but fail in all other error returns).

Thibaut Varene 8ffaeaf42e [PARISC] PDC_CHASSIS is implemented on all machines
This patch removes a limitation of the original code, so that CHASSIS
codes can be sent to all machines. On machines with a LCD panel, this
code displays "INI" during bootup, "RUN" when the system is booted and
running, "FLT" when a panic occurs, etc.

This part of the code can be enabled/disabled through CONFIG_PDC_CHASSIS

This patch also adds minimalistic support for Chassis warnings, through
a proc entry '/proc/chassis', which will reflect the warnings status (PSU
or fans failure when they happen, NVRAM battery level and temperature
thresholds overflows).

This part of the code can be enabled/disabled through CONFIG_PDC_CHASSIS_WARN

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
