When pkcs_1_v1_5_decode_emsa() returns without error and hash sizes do
not match, hash comparision is not done and digsig_verify_rsa() returns
no error.  This is a bug and this patch fixes it.

The bug was introduced in v3.3 by commit b35e286a ("lib/digsig:
pkcs_1_v1_5_decode_emsa cleanup").

  There are three bug fixes.  One from before 3.6-rc1 and two from the

  providing fixes.

   * Atomicity bug when clearing a flag and setting another.  The two
     operation should have been atomic but wasn't.  This bug has existed
     for a long time but is unlikely to have actually happened.  Fix is
     safe.  Marked for -stable.

   * If CPU hotplug cycles happen back-to-back before workers finish the
     previous cycle, the states could get out of sync and it could get
     stuck.  Fixed by waiting for workers to complete before finishing
     hotplug cycle.

   * While CPU hotplug is in progress, idle workers could be depleted
     which can then lead to deadlock.  I think both happening together
     is highly unlikely but still better to fix it and the fix isn't too
     scary.

  There's another workqueue related regression which reported a few days
  ago:

The authenc code doesn't deal with zero-length associated data
correctly and ends up constructing a zero-length sg entry which
causes a crash when it's fed into the crypto system.

This patch fixes this by avoiding the code-path that triggers
the SG construction if we have no associated data.

This isn't the most optimal fix as it means that we'll end up
using the fallback code-path even when we could still execute
the digest function.  However, this isn't a big deal as nobody
but the test path would supply zero-length associated data.

Commit 1f2bfbd0 ("kbuild: link of
vmlinux moved to a script") introduced in v3.5-rc1 broke kallsyms on
architectures which have symbol prefixes.

The --symbol-prefix argument used to be added to the KALLSYMS command
line from the architecture Makefile, however this isn't picked up by the
new scripts/link-vmlinux.sh. This resulted in symbols like
kallsyms_addresses being added which weren't correctly overriding the
weak symbols such as _kallsyms_addresses. These could then trigger
BUG_ONs in kallsyms code.

This is fixed by removing the KALLSYMS addition from the architecture
Makefile, and using CONFIG_SYMBOL_PREFIX in the link-vmlinux.sh script
to determine whether to add the --symbol-prefix argument.

To simplify both normal and CPU hotplug paths, worker management is
prevented while CPU hoplug is in progress.  This is achieved by CPU
hotplug holding the same exclusion mechanism used by workers to ensure
there's only one manager per pool.

If someone else seems to be performing the manager role, workers
proceed to execute work items.  CPU hotplug using the same mechanism
can lead to idle worker depletion because all workers could proceed to
execute work items while CPU hotplug is in progress and CPU hotplug
itself wouldn't actually perform the worker management duty - it
doesn't guarantee that there's an idle worker left when it releases
management.

This idle worker depletion, under extreme circumstances, can break
forward-progress guarantee and thus lead to deadlock.

This patch fixes the bug by using separate mechanisms for manager
exclusion among workers and hotplug exclusion.  For manager exclusion,
POOL_MANAGING_WORKERS which was restored by the previous patch is
used.  pool->manager_mutex is now only used for exclusion between the
elected manager and CPU hotplug.  The elected manager won't proceed
without holding pool->manager_mutex.

This ensures that the worker which won the manager position can't skip
managing while CPU hotplug is in progress.  It will block on
manager_mutex and perform management after CPU hotplug is complete.

Note that hotplug may happen while waiting for manager_mutex.  A
manager isn't either on idle or busy list and thus the hoplug code
can't unbind/rebind it.  Make the manager handle its own un/rebinding.

This patch restores POOL_MANAGING_WORKERS which was replaced by
pool->manager_mutex by 60373152 "workqueue: use mutex for global_cwq
manager exclusion".

There's a subtle idle worker depletion bug across CPU hotplug events
and we need to distinguish an actual manager and CPU hotplug
preventing management.  POOL_MANAGING_WORKERS will be used for the
former and manager_mutex the later.

This patch just lays POOL_MANAGING_WORKERS on top of the existing
manager_mutex and doesn't introduce any synchronization changes.  The
next patch will update it.

Note that this patch fixes a non-critical anomaly where
too_many_workers() may return %true spuriously while CPU hotplug is in
progress.  While the issue could schedule idle timer spuriously, it
didn't trigger any actual misbehavior.

During the p2v changes, the PHYS_OFFSET #define moved into a
!__ASSEMBLY__ section. This causes a XIP build to fail with

 arch/arm/kernel/head.o: In function 'stext':
 arch/arm/kernel/head.S:146: undefined reference to 'PHYS_OFFSET'

Momentarily leave the #ifndef __ASSEMBLY__ section so we can
define PHYS_OFFSET for all compilation units.

Pull HID updates from Jiri Kosina:
 "It contains a fix for Eaton Ellipse MAX UPS from Alan Stern,
  performance improvement (not processing debug data if noone is
  interested), by Henrik Rydberg, and allowing tpkbd-driven devices to
  work even with generic driver in a crippled mode, by Andres Freund."

* 'upstream-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
  HID: tpkbd: work even if the new Lenovo Keyboard driver is not configured
  HID: Only dump input if someone is listening
  HID: add NOGET quirk for Eaton Ellipse MAX UPS

Commit 43cedbf0 (SUNRPC: Ensure that
we grab the XPRT_LOCK before calling xprt_alloc_slot) is causing
hangs in the case of NFS over UDP mounts.

Since neither the UDP or the RDMA transport mechanism use dynamic slot
allocation, we can skip grabbing the socket lock for those transports.
Add a new rpc_xprt_op to allow switching between the TCP and UDP/RDMA
case.

Note that the NFSv4.1 back channel assigns the slot directly
through rpc_run_bc_task, so we can ignore that case.

c1dcad2d added a new driver configured by
HID_LENOVO_TPKBD but made the hid_have_special_driver entry non-optional which
lead to a recognized but non-working device if the new driver wasn't
configured (which is the correct default).

Merge tag 'stable/for-linus-3.6-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull Xen bug-fixes from Konrad Rzeszutek Wilk:
 * Fix for TLB flushing introduced in v3.6
 * Fix Xen-SWIOTLB not using proper DMA mask - device had 64bit but
   in a 32-bit kernel we need to allocate for coherent pages from a
   32-bit pool.
 * When trying to re-use P2M nodes we had a one-off error and triggered
   a BUG_ON check with specific CONFIG_ option.
 * When doing FLR in Xen-PCI-backend we would first do FLR then save the
   PCI configuration space. We needed to do it the other way around.

* tag 'stable/for-linus-3.6-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
  xen/pciback: Fix proper FLR steps.
  xen: Use correct masking in xen_swiotlb_alloc_coherent.
  xen: fix logical error in tlb flushing
  xen/p2m: Fix one-off error in checking the P2M tree directory.
