09690b18b7 [PARISC] Make firmware calls irqsafe-ish...
There's no reason why we shouldn't be using _irqsave instead of
_irq for any of these calls. fwiw, this fixes the
"start_kernel(): bug: interrupts were enabled early" message displayed
on bootup recently.

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.

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).

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

Flag a whole bunch of things as __read_mostly on parisc. Also flag a few
branches as unlikely() and cleanup a bit of code.

Document history of PDC_NARROW a bit as it will still show
up in an older kernel's .config file.

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!
