[MIPS] Handle I-cache coherency in flush_cache_range()
So far flush_cache_range() did't consider the I-cache largely because it
did rarely ever matter to real world code. This was working primarily
because normally code and data are don't share the same pages - with the
exception of MIPS16 code which uses address constants embedded between
the code. The following sequence of events may break the code:
o MIPS16 executable being loaded
o dynamic linker relocates the address constants embedded into the code:
o Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE
o Performs the actual relocations by writing to the pages which likely
are COW. Because no PROT_EXEC is set I-cache coherence will not be
considered.
o Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC.
This results in a call to flush_cache_range() which also does not
consider I-caches.
o => executing the page just having been relocated may now result in the
I-cache getting refilled with stale data from memory.

The early boot code maps KERNEL_TEXT_SIZE (currently 40MB) starting
from __START_KERNEL_map. The kernel itself only needs _text to _end
mapped in the high alias. On relocatible kernels the ASM setup code
adjusts the compile time created high mappings to the relocation. This
creates invalid pmd entries for negative offsets:
0xffffffff80000000 -> pmd entry:
ffffffffff2001e3
It points outside of the physical address space and is marked present.
This starts at the virtual address __START_KERNEL_map and goes up to
the point where the first valid physical address (0x0) is mapped.
Zap the mappings before _text and after _end right away in early
boot. This removes also the invalid entries.

V4L/DVB (7188): radio-si470x version 1.0.6
This patch combines all the finished discussions and its resulting patches from
the mailing list.
The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of
small issues, that are fixed with this patch now. For me the most interesting
thing is, that it's now safer to use it on other architectures.
The history for version 1.0.6 is:
- fixed coverity checker warnings in *_usb_driver_disconnect
- probe()/open() race by correct ordering in probe()
- DMA coherency rules by separate allocation of all buffers
- use of endianness macros
- abuse of spinlock, replaced by mutex
- racy handling of timer in disconnect, replaced by delayed_work
- racy interruptible_sleep_on(), replaced with wait_event_interruptible()
- handle signals in read()
The driver is tested with all Debian/testing radio programs and rdsd. The patch
is tested against checkpatch.pl v1.12.

V4L/DVB (7179): Allow more than one em28xx board
em28xx driver is capable of handling more than one usb device. However, isoc
transfers require a large amount of data to be transfered.
Before this patch, just one em28xx board were enough to allocate more than 50%
URBs:
T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8
B: Alloc=480/800 us (60%), #Int= 0, #Iso= 2
D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1
So, only one board could use an USB host at the same time. After the patch, it
is possible to use more than one em28xx at the same time, on the same usb host,
if the image size is slower or equal to 345600, since those images will
require about 30% of the URBs:
T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8
B: Alloc=232/800 us (29%), #Int= 0, #Iso= 2
D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1
So, in thesis, after the patch, it would be possible to use up to 3 boards by
each usb host, if the devices are generating small images.

V4L/DVB (7091): radio-si470x improvements and seldom problem fixed in tuning functions
I updated the radio-si470x driver another time. Here are the commented history entries:
- number of seek_retries changed to tune_timeout
The last versions checked for the end of frequency tuning by polling a si470x register.
Therefore polling depended on the usb utilization.
This was changed to have a constant timeout now.
- fixed problem with incomplete tune operations by own buffers
The last version used a shared buffer to assembly the USB HID reports.
It sometimes happened, that multiple functions were modifing this buffer simultanuously.
When sending such reports, the hardware returned USB stalls (-EPIPE).
Now buffers of the correct size (smaller than before) are allocated as local variables.
- optimization of variables
The size of some variables has been reduced to allow the compiler to generate more optimized code.
- improved error logging
At some important location, error checking was improved.
Especially the usb transfers to access si470x registers and the tuning functions were modified.

V4L/DVB (7133): Fix Kconfig dependencies
As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.
This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.
After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.
This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

[XFS] Remove Makefile wrappers in XFS
Makefile (and Kbuild) would include Makefile-linux-26 I doubt XFS will
really still compile on 2.4; so drop that. This moves Makefile-linux-26
into Makefile and drops Kbuild. Also having wrappers as both Kbuild and
Makefile seemed redundant anyways.
The patch is relatively large because it renames a file, but no functional
changes.
