6ad36fe2b4 dm raid1: one kmirrord per mirror
This patch replaces the single instance of kmirrord by one instance per mirror
set.  This change is required to avoid a deadlock in kmirrord when the
persistent dirty log of a mirror itself resides on a mirror.  The single
instance of kmirrord then issues a sync write to the dirty log in write_bits
which gets deferred to kmirrord itself later in the call chain.  But kmirrord
never does the deferred work because it is still waiting for the sync
write_bits.

_mirror_sets is removed as it no longer needed, and we always flush the
workqueue before destroying it to ensure all work is complete before
destroying it.

5e6d444ea1 SLUB: rework slab order determination
In some cases SLUB is creating uselessly slabs that are larger than
slub_max_order. Also the layout of some of the slabs was not satisfactory.

45edfa580b SLUB: include lifetime stats and sets of cpus / nodes in tracking output
We have information about how long an object existed and about the nodes and
cpus where the allocations and frees took place.  Add that information to the
tracking output in /sys/slab/xx/alloc_calls and /sys/slab/free_calls

This will then enable slabinfo to output nice reports like this:

41ecc55b8a SLUB: add CONFIG_SLUB_DEBUG
CONFIG_SLUB_DEBUG can be used to switch off the debugging and sysfs components
of SLUB.  Thus SLUB will be able to replace SLOB.  SLUB can arrange objects in
a denser way than SLOB and the code size should be minimal without debugging
and sysfs support.

Note that CONFIG_SLUB_DEBUG is materially different from CONFIG_SLAB_DEBUG.
CONFIG_SLAB_DEBUG is used to enable slab debugging in SLAB.  SLUB enables
debugging via a boot parameter.  SLUB debug code should always be present.

CONFIG_SLUB_DEBUG can be modified in the embedded config section.

26a7bd0302 SLUB: get rid of finish_bootstrap
Its only purpose was to bring some sort of symmetry to sysfs usage when
dealing with bootstrapping per cpu flushing.  Since we do not time out slabs
anymore we have no need to run finish_bootstrap even without sysfs.  Fold it
back into slab_sysfs_init and drop the initcall for the !SYFS case.

65c02d4cfb SLUB: add support for dynamic cacheline size determination
SLUB currently assumes that the cacheline size is static.  However, i386 f.e.
supports dynamic cache line size determination.

Use cache_line_size() instead of L1_CACHE_BYTES in the allocator.

That also explains the purpose of SLAB_HWCACHE_ALIGN.  So we will need to keep
that one around to allow dynamic aligning of objects depending on boot
determination of the cache line size.

de372ecd80 Documentation/i386/boot.txt: update and correct
In the process of rewriting the x86 setup code, I found a number of
inaccuracies and outdated recommendations in the boot protocol
documentation.  Revamp to make it more up to date.

In particular, the common use of the heap actually requires (slightly)
more than 4K of heap plus stack, which is the recommended amount in
the document; currently the code compensates by being smaller than
specified, but we can't assume that will be true forever.  Thus,
recommend that if we have a modern bzImage kernel, that the bootloader
maximizes the available space.

Revert commit bd53f96ca5.

Con says:

This is no good, sorry. The one I saw originally was with the staircase
deadline cpu scheduler in situ and was different.

  #define TASK_PREEMPTS_CURR(p, rq) \
     ((p)->prio < (rq)->curr->prio)
     (((p)->prio < (rq)->curr->prio) && ((p)->array == (rq)->active))

This will fail to wake up a runqueue for a task that has been migrated to the
expired array of a runqueue which is otherwise idle which can happen with smp
balancing,

01e73be3c8 Revert "fbdev: ignore VESA modes if framebuffer is disabled"
This reverts commit 464bdd33e9.

Peter Anvin correctly points out that VESA modes have nothing to do with
frame buffers per se - they are often just regular extended text modes.
Disabling them just because we don't have frame buffer support is very
wrong.

1605b8471d [CRYPTO] cryptomgr: Fix use after free
By the time kthread_run returns the param may have already been freed
so writing the returned thread_struct pointer to param is wrong.

In fact, we don't need it in param anyway so this patch simply puts it
on the stack.

34768bc832 [SPARC64] PCI: Use root list of pbm's instead of pci_controller_info's
The idea is to move more and more things into the pbm,
with the eventual goal of eliminating the pci_controller_info
entirely as there really isn't any need for it.

This stage of the transformations requires some reworking of
the PCI error interrupt handling.

It might be tricky to get rid of the pci_controller_info parenting for
a few reasons:

1) When we get an uncorrectable or correctable error we want
   to interrogate the IOMMU and streaming cache of both
   PBMs for error status.  These errors come from the UPA
   front-end which is shared between the two PBM PCI bus
   segments.

   Historically speaking this is why I choose the datastructure
   hierarchy of pci_controller_info-->pci_pbm_info

2) The probing does a portid/devhandle match to look for the
   'other' pbm, but this is entirely an artifact and can be
   eliminated trivially.

What we could do to solve #1 is to have a "buddy" pointer from one pbm
to another.
