MIPS: jz4740: Fix Kbuild Platform file.
MIPS: Repair Kbuild make clean breakage.
When running make clean, Kbuild doesn't process the .config file, so nothing
generates a platform-y variable. We can get it to descend into the platform
directories by setting $(obj-).
The dec Platform file was unconditionally setting platform-, obliterating
its previous contents and preventing some directories from being cleaned.
This is change to an append operation '+=' to allow cavium-octeon to be
cleaned.

kvm reloads the host's fs and gs blindly, however the underlying segment
descriptors may be invalid due to the user modifying the ldt after loading
them.
Fix by using the safe accessors (loadsegment() and load_gs_index()) instead
of home grown unsafe versions.
This is CVE-2010-3698.

Commit a7f8388e accidentally removed it... Al explains:
"Sorry, reordering breakage. In the signals tree here I have
static inline void sig_set_blocked(struct sigset_t *set)
...
and it's used all over the place (including quite a few places where
we currently have sigprocmask(SIG_SETMASK, set, NULL), which is what
it's equivalent to). With that done, m32r doesn't use _BLOCKABLE
anywhere, so it got removed. And that chunk got picked when I'd been
reordering the queue to pull the arch-specific fixes in front.
Sorry."

Commit f81f2f7c (ubd: drop unnecessary rq->sector manipulation)
dropped request->sector manipulation in preparation for global request
handling cleanup; unfortunately, it incorrectly assumed that the
updated sector wasn't being used.
ubd tries to issue as many requests as possible to io_thread. When
issuing fails due to memory pressure or other reasons, the device is
put on the restart list and issuing stops. On IO completion, devices
on the restart list are scanned and IO issuing is restarted.
ubd issues IOs sg-by-sg and issuing can be stopped in the middle of a
request, so each device on the restart queue needs to remember where
to restart in its current request. ubd needs to keep track of the
issue position itself because,
* blk_rq_pos(req) is now updated by the block layer to keep track of
_completion_ position.
* Multiple io_req's for the current request may be in flight, so it's
difficult to tell where blk_rq_pos(req) currently is.
Add ubd->rq_pos to keep track of the issue position and use it to
correctly restart io_req issue.

akiphie points out that a.out core-dumps have that odd task struct
dumping that was never used and was never really a good idea (it goes
back into the mists of history, probably the original core-dumping
code). Just remove it.
Also do the access_ok() check on dump_write(). It probably doesn't
matter (since normal filesystems all seem to do it anyway), but he
points out that it's normally done by the VFS layer, so ...
[ I suspect that we should possibly do "vfs_write()" instead of
calling ->write directly. That also does the whole fsnotify and write
statistics thing, which may or may not be a good idea. ]
And just to be anal, do this all for the x86-64 32-bit a.out emulation
code too, even though it's not enabled (and won't currently even
compile)
