Benjamin Herrenschmidt 25e81f925d [POWERPC] Make isa_mem_base common to 32 and 64 bits
This defines isa_mem_base on both 32 and 64 bits (it used to be 32 bits
only).  This avoids a few ifdef's in later patches and potentially can
allow support for VGA text mode on 64 bits powerpc.

David Gibson 430b01e8f5 [POWERPC] Kill flatdevtree.c
Now that earlier patches have switched the bootwrapper to using libfdt
for device tree manipulation, this patch removes the now unused
flatdevtree.c and related files.

David Gibson 2f0dfeaa84 [POWERPC] Use embedded libfdt in the bootwrapper
This incorporates libfdt (from the source embedded in an earlier
commit) into the wrapper.a library used by the bootwrapper.  This
includes adding a libfdt_env.h file, which the libfdt sources need in
order to integrate into the bootwrapper environment, and a
libfdt-wrapper.c which provides glue to connect the bootwrapper's
abstract device tree callbacks to the libfdt functions.

In addition, this changes the various wrapper and platform files to
use libfdt functions instead of the older flatdevtree.c library.

will schmidt b3b9595f50 [POWERPC] Update xmon slb code
This adds a bit more detail to the xmon SLB output.  When the valid
bit is set, this displays the ESID and VSID values, as well as
decoding the segment size -- 1T or 256M -- and displaying the LLP
bits.  This supresses the output for any slb entries that contain only
zeros.

sample output from power6 (1T segment support):

Michael Neuling 584f8b71a2 [POWERPC] Use SLB size from the device tree
Currently we hardwire the number of SLBs to 64, but PAPR says we
should use the ibm,slb-size property to obtain the number of SLB
entries.  This uses this property instead of assuming 64.  If no
property is found, we assume 64 entries as before.

This soft patches the SLB handler, so it shouldn't change performance
at all.

helped up things on MIPS, but was wrong for everything else.  As Ralf

  "It seems the whole MIPS resource managment is complicated enough (out

   actually memory mapped on MIPS only makes the confusion worse, sigh."

Benjamin Herrenschmidt 6d98bda79b powerpc: Fix IDE legacy vs. native fixups
PowerMac and CHRP/BriQ platforms have quirks to switch some IDE
controllers from legacy mode to fully native mode. Those quirks
however will not work properly anymore due to a change to the
generic code to better handle legacy IDE resources.

This fixes it by moving those quirk to "early" quirks (so they
run before resources are probed for the devices) and clearing
all BARs after the conversion to force a reallocation of sane
values.

which is for I_NEW, not I_LOCK or I_SYNC so that behaviour is correct.

David Chinner a7430847fc [XFS] Fix broken inode cluster setup.
The radix tree based inode caches did away with the inode cluster hashes,
replacing them with a bunch of masking and gang lookups on the radix tree.

This masking got broken when moving the code to per-ag radix trees and
indexing by agino # rather than straight inode number. The result is
clustered inode writeback does not cluster and things can go extremely
slowly when there are lots of inodes to write.

Fix it up by comparing the agino # of the inode we just looked up to the
index of the cluster we are looking for.
