An earlier update changed some calls from simple_strotl to strict_strtol but
did not account for the differences in the syntax between the calls.
simple_strotl returns the integer; strict_strtol returns an error code and
takes a pointer to the result. As it was, NULL was being passed in place of
the result, which led to failures during kernel initialization when using
YAMON.

Bug originally found and reported by Julia Lawall <julia@diku.dk>. I
decieded that the whole error check was mostly useless paranoia and should
be discarded. It would only ever trigger if r3k_have_wired_reg has a wrong

Claim the initrd memory exclusively, and order other memory
reservations beforehand. This allows us to determine whether
the initrd memory was overwritten, and disable the initrd in
that case.
This avoids a 'bad page state' bug.

This series of patches adds a driver for the SGI UV GRU. The driver is
still in development but it currently compiles for both x86_64 & IA64.
All simple regression tests pass on IA64. Although features remain to be
added, I'd like to start the process of getting the driver into the
kernel. Additional kernel drivers will depend on services provide by the
GRU driver.
The GRU is a hardware resource located in the system chipset. The GRU
contains memory that is mmaped into the user address space. This memory
is used to communicate with the GRU to perform functions such as
load/store, scatter/gather, bcopy, AMOs, etc. The GRU is directly
accessed by user instructions using user virtual addresses. GRU
instructions (ex., bcopy) use user virtual addresses for operands.
The GRU contains a large TLB that is functionally very similar to
processor TLBs. Because the external contains a TLB with user virtual
address, it requires callouts from the core VM system when certain types
of changes are made to the process page tables. There are several MMUOPS
patches currently being discussed but none has been accepted into the
kernel. The GRU driver is built using version V18 from Andrea Arcangeli.
This patch:
Contains the definitions of the hardware GRU data structures that are used
by the driver to manage the GRU.

Ingo Molnar provided a fix to not call _PPC at processor driver
initialization time in "[PATCH] ACPI: fix cpufreq regression" (git
commit e4233dec749a3519069d9390561b5636a75c7579)
But it can still happen that _PPC is called at processor driver
initialization time.
This patch should make sure that this is not possible anymore.

The code to handle writes to /proc/ppc64/lparcfg incorrectly
assumes that the return code from the helper routines to update
processor or memory entitlement return a hcall return value. It
then assumes any non-hcall return value is bad and sets the return
code for the write to be -EIO.
The update_[mp]pp routines can return values other than a hcall
return value. This patch removes the automatic setting of any
return code that is not an hcall return value from these routines
to -EIO.
