PARISC fixes from James Bottomley: "This is a set of build fixes to get the cross compiled architecture testbeds building again" * tag 'parisc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/parisc-2.6: [PARISC] don't unconditionally override CROSS_COMPILE for 64 bit. [PARISC] include <linux/prefetch.h> in drivers/parisc/iommu-helpers.h [PARISC] fix compile break caused by iomap: make IOPORT/PCI mapping functions conditional

UBIFS is a file system for flash devices which works on top of UBI.
config UBIFS_FS_XATTR
bool "Extended attributes support"
depends on UBIFS_FS
help
This option enables support of extended attributes.
config UBIFS_FS_ADVANCED_COMPR
bool "Advanced compression options"
depends on UBIFS_FS
help
This option allows to explicitly choose which compressions, if any,
are enabled in UBIFS. Removing compressors means inability to read
existing file systems.
If unsure, say 'N'.
config UBIFS_FS_LZO
bool "LZO compression support" if UBIFS_FS_ADVANCED_COMPR

default y
help
LZO compressor is generally faster than zlib but compresses worse.
Say 'Y' if unsure.
config UBIFS_FS_ZLIB
bool "ZLIB compression support" if UBIFS_FS_ADVANCED_COMPR
depends on UBIFS_FS
default y
help
Zlib compresses better than LZO but it is slower. Say 'Y' if unsure.
# Debugging-related stuff
config UBIFS_FS_DEBUG
bool "Enable debugging support"
depends on UBIFS_FS
select DEBUG_FS
select KALLSYMS
help
This option enables UBIFS debugging support. It makes sure various
assertions, self-checks, debugging messages and test modes are compiled
in (this all is compiled out otherwise). Assertions are light-weight
and this option also enables them. Self-checks, debugging messages and
test modes are switched off by default. Thus, it is safe and actually
recommended to have debugging support enabled, and it should not slow
down UBIFS. You can then further enable / disable individual debugging
features using UBIFS module parameters and the corresponding sysfs
interfaces.
