page and a relative offset into that page around, and returns the current
xfs_iomap_t if the block at the specified offset fits into it, or a NULL
pointer otherwise. This patch passed the full 64bit offset into the inode
that all callers have anyway, and changes the return value to a simple
boolean. Also the function gets a more descriptive name: xfs_iomap_valid.

PPC32 is still using asm-generic/4level-fixup.h, but asm-powerpc/page.h
was defining pud_t and pgd_t. Depending on the order in which files
got included, this could result in a compilation error. Tweak the ifdef
so that page.h doesn't try to define pud_t on ppc32 (which uses 2-level
page tables).

Removing the dependency on the boot image build was good, but it also
meant that the $< expansion by make needed to be done explicitly.

Also, drop __exit marker from ipv6_netfilter_fini() as this

allows us to submit much larger I/Os instead of sending down lots of small
buffer_heads. To do this we need to have a rather complicated I/O
submission and completion tracking infrastructure. Part of the latter has
been merged already a long time ago for direct I/O support. Part of the
problem is that we need to track sub-pagesize regions and for that we
still need buffer_heads for the time beeing. Long-term I hope we can move
to better data strucutures and/or maybe move this to fs/mpage.c instead of
having it in XFS. Original patch from Nathan Scott with various updates
from David Chinner and Christoph Hellwig.

was caused by ENOSPC but not Rreclaimed by xfs_release or xfs_inactive.
The fix changed the condition in xfs_release and xfs_inactive to invoke
xfs_inactive_free_eofblocks for this special case, changed
xfs_inactive_free_eofblocks to clean the delayed blks after eof. It also
changed xfs_write to set correct eof when ENOSPC occurs.

To make iSeries just a teensy bit less special, create ibm,pft-size properties
in the iSeries device tree. We can then rely on htab_dt_scan_pftsize() to set
ppc64_pft_size for us.

Updated Kconfig & Makefiles in prep for adding support for the Freescale
MPC83xx family of processors to arch/powerpc. Moved around some config
options that are more globally applicable to other PowerPC processors.
Added a temporary config option (83xx) to match existing arch/ppc support
for the MPC83xx line.
