At boot time, determine the D-cache, I-cache and E-cache size and
line-size. Use them in cache flushes when appropriate.
This change was motivated by discovering that the D-cache on
UltraSparc-IIIi and later are 64K not 32K, and the flushes done by the
Cheetah error handlers were assuming a 32K size.
There are still some pieces of code that are hard coding things and
will need to be fixed up at some point.
While we're here, fix the D-cache and I-cache parity error handlers
to run with interrupts disabled, and when the trap occurs at trap
level > 1 log the event via a counter displayed in /proc/cpuinfo.

This creates the directory structure under arch/powerpc and a bunch
of Kconfig files. It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.
For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes
to files in those directories and files outside arch/powerpc.
The boot directory is still not merged. That's going to be interesting.

The trick is that we do the kernel linear mapping TLB miss starting
with an instruction sequence like this:
ba,pt %xcc, kvmap_load
xor %g2, %g4, %g5
succeeded by an instruction sequence which performs a full page table
walk starting at swapper_pg_dir.
We first take over the trap table from the firmware. Then, using this
constant PTE generation for the linear mapping area above, we build
the kernel page tables for the linear mapping.
After this is setup, we patch that branch above into a "nop", which
will cause TLB misses to fall through to the full page table walk.
With this, the page unmapping for CONFIG_DEBUG_PAGEALLOC is trivial.

Currently we just ignore the device, which means there are a few
arrays out there that we don't find.
This patch updates the scsi_report_lun_scan() to take a target instead
of a device so it can be called on a return of
SCSI_SCAN_TARGET_PRESENT, which is what a PQ 3 device returns.

powerpc: Merge semaphore.h
Adopted the ppc64 version of semaphore.h. The 32-bit version used
smp_wmb(), but recent updates to atomic.h mean this is no longer required.
The 64-bit version made use of unlikely(), which has been retained in the
combined version.
This patch requires the recent atomic.h patch.

The spinlock_types.h merge renamed the structure for raw_spinlock_t to

If CONFIG_PROC_FS is not selected, the compiler emits this warning:
net/core/neighbour.c:64: warning: `neigh_stat_seq_fops' defined but not used
Which is correct, because neigh_stat_seq_fops is in fact only
initialized and used by code that is protected by CONFIG_PROC_FS. So
this patch fixes that up.

hostap_pci and hostap_plx drivers still use PCI driver names
"prism2_pci" and "prism2_plx" respectively. This is unfriendly to
linux-wlan-ng, which uses the same names. So, if e.g. hostap_pci and
prism2_pci are loaded, they will "share" /sys/bus/pci/drivers/prism2_plx
directory.
Change PCI driver names of hostap_pci and hostap_plx to be equal to
their module names.
