Gentoo users with kernels with selinux compiled in, and coreutils compiled
with acl support, noticed that they could not copy files on tmpfs using
'cp'.
cp (compiled with acl support) copies the file, lists the extended
attributes on the old file, copies them all to the new file, and then
exits. However the listxattr() calls were failing with this odd behaviour:
llistxattr("a.out", (nil), 0) = 17
llistxattr("a.out", 0x7fffff8c6cb0, 17) = -1 ERANGE (Numerical result out of
range)
I believe this is a simple problem in the logic used to check the buffer
sizes; if the user sends a buffer the exact size of the data, then its ok
:)

sleep states, because it left TIF_POLLING_NRFLAG active even though
those states do not actually poll the reschedule flag at all. As a
result, the CPU wouldn't get sent an IPI when it was to be woken up, and
would only notice that it had runnable processes on the next timer tick.

[SCSI] sg: fix a bug in st_map_user_pages failure path
sg's st_map_user_pages is modelled on an earlier version of st's
sgl_map_user_pages, and has the same bug: if get_user_pages got some but
not all of the pages, then those got were released, but the positive res
code returned implied that they were still to be freed.

[SCSI] sg and st unmap_user_pages allow PageReserved
2.6.15-rc1 made sg's st_unmap_user_pages and st's sgl_unmap_user_pages
BUG on a PageReserved page. But that's wrong: they could be unmapping
the ZERO_PAGE, which is marked PG_reserved; and perhaps others (while
get_user_pages is still permitted on VM_PFNMAP areas - that may change).
More change is needed here: sg claims to dirty even pages written from,
and st claims not to dirty even pages read into; and SetPageDirty is not
adequate for this nowadays. Fixes to those follow in a later patch: for
the moment just fix the 2.6.15 regression.

[PATCH] powerpc/pseries: Fix TCE building with 64k pagesize
Must adjust tcenum and npages by TCE_PAGE_FACTOR to convert between
64KB pages and TCE (4K) pages. (This is done in other places, except
for this one location.)

[PATCH] V4l/dvb: Restore missing tuner definition for Hauppauge tuner type 0x103
Type 0x103 ("TCL MFNM05-4") in the Hauppauge eeprom is a more recent tuner
that maps to TUNER_PHILIPS_FM1236_MK3. This had been previously defined but
due to some accident the definition got removed. This change restores that
definition. Change committed on advice from Hans Verkuil
<hverkuil@xs4all.nl>, who thinks he's the one who had accidentally removed it
before.
