Since the powerpc 64k pages patch went in, systems that have SLBs
(like Power4 iSeries) needed to have slb_initialize called to set up
some variables for the SLB miss handler. This was not being called
on the boot processor on iSeries, so on single cpu iSeries machines,
we would get apparent memory curruption as soon as we entered user mode.
This patch fixes that by calling slb_initialize on the boot cpu if the
processor has an SLB.

This fixes several problems with the lparcfg code. In case
someone gets a sense of deja-vu, part of this was submitted last Sep, I
thought the changes went in, but either got backed out, or just got
lost.
First, change the local_buffer declaration to be unsigned char *. We
had a bad-math problem in a 2.4 tree which was built with a
"-fsigned-char" parm. I dont believe we ever build with that parm
now-a-days, but to be safe, I'd prefer the declaration be explicit.
Second, fix a bad math calculation for splpar_strlen.
Third, on the rtas_call for get-system-parameter, pass in
RTAS_DATA_BUF_SIZE for the rtas_data_buf size, instead of letting random
data determine the size. Until recently, we've had a sufficiently
large 'random data' value get passed in, so the function just happens to
have worked OK. Now it's getting passed a '0', which causes the
rtas_call to return success, but no data shows up in the buffer.
(oops!). This was found by the LTC test org.
This is in a branch of code that only gets run on SPLPAR systems.
Tested on power5 Lpar.

This forces the processing of EEH PCI events to be serialized,

This patch removes the decap_state argument from the xfrm input hook.
Previously this function allowed the input hook to share state with
the post_input hook. The latter has since been removed.
The only purpose for it now is to check the encap type. However, it
is easier and better to move the encap type check to the generic
xfrm_rcv function. This allows us to get rid of the decap state
argument altogether.

switch_mm() changes the mm state and does a tsb_context_switch()
first, then we do the cpu register state switch which changes
current_thread_info() and current().
So it's safer to check the PGD physical address stored in the
trap block (which will be updated by the tsb_context_switch() in
switch_mm()) than current->active_mm.
Technically we should never run here in between those two
updates, because interrupts are disabled during the entire
context switch operation. But some day we might like to leave
interrupts enabled during the context switch and this change
allows that to happen without any surprises.

I was grepping through the code and some `grep ganularity -R .` didn't
catch what I thought. Then looking closer I saw the term "granuality"
used in only four places (in comments) and granularity in many more
places describing the same idea. Some other facts:
dictionary.com does not know such a word
define:granuality on google is not found (and pages for granuality are
mostly related to patches to the kernel)
it has not been discussed as a term on LKML, AFAICS (=Can Search)
To be consistent, I think granularity should be used everywhere.
