The IODA reset can fail in cases where the PHB has encounted a fatal error
during early boot. Typically this is due a malfunctioning device directly below
the root complex, but can occur for other reasons. This patch fixes the problem
by forcing a reset of the PHB if we get an error back from

The SLB initialisation code is spread around a bit between prom.c and
hash_utils_64.c. Consolidate it all in hash_utils_64.c.
This slightly changes the timing of when mmu_slb_size is initialised,
but that should have no effect.

On machines with 1TB segments and a 32-entry SLB it's quite hard to
cause sufficient SLB pressure to trigger bugs caused due to badly
timed SLB faults.
We have seen this in the past and a few years ago added the
disable_1tb_segments command line option to force the use of 256MB
segments. However
The recent rewrite of the SLB code into C included the assumption that
all CPUs we run on have at least 32 SLB entries. This is currently
true but a bit fragile as the SLB size is actually defined by the
device tree and so could theoretically change at any time.
The assumption is encoded in the
It's easier to reason about the code if we only set mmu_slb_size in
one place, so convert open-coded assignments to use slb_set_size().

Currently in system_call_exit() we have an optimisation where we
disable MSR_RI (recoverable interrupt) and MSR_EE (external interrupt
enable) in a single mtmsrd instruction.
Unfortunately this will no longer work with THREAD_INFO_IN_TASK,
because then the load of TI_FLAGS might fault and
'nobats' kernel parameter or some options like CONFIG_DEBUG_PAGEALLOC
deny the use of BATS for mapping memory.
This patch makes sure that the specific wii RAM mapping function
takes it into account as well.

In Kbuild, if_changed and friends must have FORCE as a prerequisite.
Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common
pattern to get the names of all the prerequisites except phony targets.
Add real-prereqs as a shorthand.
Note:
We cannot replace $(filter %.o,$^) in
