This reverts commit 9d02b43dee0d7fb18dfb13a00915550b1a3daa9f.
We are doing this b/c on 32-bit PVonHVM with older hypervisors
(Xen 4.1) it ends up bothing up the start_info. This is bad b/c
we use it for the time keeping, and the timekeeping code loops

omapdrm uses "select" in Kconfig to enable omapdss. This doesn't work
correctly, as "select" forces omapdss to be enabled in the config even
if it normally could not be enabled because of missing Kconfig
dependencies.
This causes a build break on ARM, when using allyesconfig:
drivers/video/omap2/dss/dss.c: In function 'dss_calc_clock_div':
drivers/video/omap2/dss/dss.c:572:20: error: 'CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK' undeclared (first use in this function)

commit 195e672a76056478cc79f5c48343164c9237852e
OMAPDSS: DPI: Remove cpu_is_xxxx checks

other cpu_is_* predicates whereas it includes cpu_is_omap3630().
So on an omap3630, code that was previously enabled by

There is a check in the completion path for osd requests that
ensures the number of pages allocated is enough to hold the amount
of incoming data expected.
For bio requests coming from rbd the "number of pages" is not really
meaningful (although total length would be). So stop requiring that
nr_pages be supplied for bio requests. This is done by checking
whether the pages pointer is null before checking the value of
nr_pages.
Note that this value is passed on to the messenger, but there it's
only used for debugging--it's never used for validation.
While here, change another spot that used r_pages in a debug message
inappropriately, and also invalidate the r_con_filling_msg pointer
after dropping a reference to it.

Currently, if the OSD client finds an osd request has had a bio list
attached to it, it drops a reference to it (or rather, to the first
entry on that list) when the request is released.
The code that added that reference (i.e., the rbd client) is
therefore required to take an extra reference to that first bio
structure.
The osd client doesn't really do anything with the bio pointer other
than transfer it from the osd request structure to outgoing (for
writes) and ingoing (for reads) messages. So it really isn't the
right place to be taking or dropping references.
Furthermore, the rbd client already holds references to all bio
structures it passes to the osd client, and holds them until the
request is completed. So there's no need for this extra reference
whatsoever.
So remove the bio_put() call in ceph_osdc_release_request(), as
well as its matching bio_get() call in rbd_osd_req_create().
This change could lead to a crash if old libceph.ko was used with
new rbd.ko. Add a compatibility check at rbd initialization time to
avoid this possibilty.

An upcoming change implements semantic change that could lead to
a crash if an old version of the libceph kernel module is used with
a new version of the rbd kernel module.
In order to preclude that possibility, this adds a compatibilty
check interface. If this interface doesn't exist, the modules are
obviously not compatible. But if it does exist, this provides a way
of letting the caller know whether it will operate properly with
this libceph module.
Perhaps confusingly, it returns false right now. The semantic
change mentioned above will make it return true.

An open request for a mapped rbd image can arrive while removal of
that mapping is underway. We need to prevent such an open request
from succeeding. (It appears that Maciej Galkiewicz ran into this
problem.)
Define and use a "removing" flag to indicate a mapping is getting
removed. Set it in the remove path after verifying nothing holds
the device open. And check it in the open path before allowing the
open to proceed. Acquire the rbd device's lock around each of these
spots to avoid any races accessing the flags and open_count fields.

When we register an osd request to linger, it means that request
will stay around (under control of the osd client) until we've
unregistered it. We do that for an rbd image's header object, and
we keep a pointer to the object request associated with it.
Keep a reference to the watch object request for as long as it is
registered to linger. Drop it again after we've removed the linger
registration.

When we receive notification of a change to an rbd image's header

This patch fully implements the new request tracking code for rbd
I/O requests.
Each I/O request to an rbd image will get an rbd_image_request
structure allocated to track it. This provides access to all
information about the original request, as well as access to the
set of one or more object requests that are initiated as a result
of the image request.
An rbd_obj_request structure defines a request sent to a single osd
object (possibly) as part of an rbd image request. An rbd object
request refers to a ceph_osd_request structure built up to represent
the request; for now it will contain a single osd operation. It
also provides space to hold the result status and the version of the
object when the osd request completes.
An rbd_obj_request structure can also stand on its own. This will
be used for reading the version 1 header object, for issuing
acknowledgements to event notifications, and for making object
method calls.
All rbd object requests now complete asynchronously with respect
to the osd client--they supply a common callback routine.

Petr says: "
I've analysed the bug and I think that xen_iret() cannot cope with
mangled DS, in this case zeroed out (null selector/descriptor) by either
xen_failsafe_callback() or RESTORE_REGS because the corresponding LDT
entry was invalidated by the reproducer. "
Jan took a look at the preliminary patch and came up a fix that solves
this problem:
"This code gets called after all registers other than those handled by
IRET got already restored, hence a null selector in %ds or a non-null
one that got loaded from a code or read-only data descriptor would
cause a kernel mode fault (with the potential of crashing the kernel
as a whole, if panic_on_oops is set)."
The way to fix this is to realize that the we can only relay on the
registers that IRET restores. The two that are guaranteed are the
%cs and %ss as they are always fixed GDT selectors. Also they are
inaccessible from user mode - so they cannot be altered. This is
the approach taken in this patch.
Another alternative option suggested by Jan would be to relay on
the subtle realization that using the %ebp or %esp relative references uses
the %ss segment. In which case we could switch from using %eax to %ebp and
would not need the %ss over-rides. That would also require one extra
instruction to compensate for the one place where the register is used
as scaled index. However Andrew pointed out that is too subtle and if
further work was to be done in this code-path it could escape folks attention
and lead to accidents.

have accumulated meanwhile.
1) Revert two r8169 changes to fix suspend/resume for some users,
from Francois Romieu.
2) PCI dma mapping errors in atl1c are not checked for and this cause
hard crashes for some users, from Xiong Huang.
3) In 3.8.x we merged the removal of the EXPERIMENTAL dependency for
'dlm' but the same patch for 'sctp' got lost somewhere, resulting
in the potential for build errors since there are cross
dependencies. From Kees Cook.
4) SCTP's ipv6 socket route validation makes boolean tests
incorrectly, fix from Daniel Borkmann.
5) mac80211 does sizeof(ptr) instead of (sizeof(ptr) * nelem), from
Cong Ding.
6) arp_rcv() can crash on shared non-linear packets, from Eric
Dumazet.
7) Avoid crashes in macvtap by setting ->gso_type consistently in
ixgbe, qlcnic, and bnx2x drivers. From Michael S Tsirkin and
Alexander Duyck.
8) Trinity fuzzer spots infinite loop in __skb_recv_datagram(), fix
from Eric Dumazet.
9) STP protocol frames should use high packet priority, otherwise an
overloaded bridge can get stuck. From Stephen Hemminger.
10) The HTB packet scheduler was converted some time ago to store
internal timestamps in nanoseconds, but we don't convert back into
psched ticks for the user during dumps. Fix from Jiri Pirko.
11) mwl8k channel table doesn't set the .band field properly,
resulting in NULL pointer derefs. Fix from Jonas Gorski.
12) mac80211 doesn't accumulate channels properly during a scan so we
can downgrade heavily to a much less desirable connection speed.
Fix from Johannes Berg.
13) PHY probe failure in stmmac can result in resource leaks and
double MDIO registery later, from Giuseppe CAVALLARO.
14) Correct ipv6 checksumming in ip6t_NPT netfilter module, also fix
address prefix mangling, from YOSHIFUJI Hideaki."

Pull x86 fixes from Peter Anvin:
"One (hopefully) last batch of x86 fixes. You asked for the patch by
patch justifications, so here they are:
x86, MCE: Retract most UAPI exports
This one unexports from userspace a bunch of definitions which should
never have been exported. We really don't want to create an
accidental legacy here.
x86, doc: Add a bootloader ID for OVMF
This is a documentation-only patch, just recording the official
assignment of a boot loader ID.
x86: Do not leak kernel page mapping locations
Security: avoid making it needlessly easy for user space to probe the
kernel memory layout.
x86/mm: Check if PUD is large when validating a kernel address
Prevent failures using /proc/kcore when using 1G pages.
x86/apic: Work around boot failure on HP ProLiant DL980 G7 Server systems
Works around a BIOS problem causing boot failures on affected hardware."

Change to my private email, change to my shiny new kernel.org repos,
and drop outdated entry from the former maintainer. Drop my PCA entry,
too, since it belongs to the I2C realm anyhow.
