Ben Lahaise e763b793f7 [PATCH] uml: switch_mm fix
Not quite, something along the lines of the patch below works correctly (and
makes aio performance not suffer from multiple second delays), as skas0 mode
correctly switches mm contexts, unlike TT (which should probably get nuked
from the kernel now that skas0 seems to be working).

Bodo Stroesser 0e76422ca5 [PATCH] uml: fix UML network driver endianness bugs
ifa->ifa_address and ifa->ifa_mask are defined as __u32, but used as if they
were char[4].

Network code uses htons() to convert it.  So UML's method to access these
fields is wrong for bigendians (e.g.  s390)

I replaced bytewise copying by memcpy(), maybe even that might be removed, if
ifa->ifa_address/mask may be used immediately.

Paolo 'Blaisorblade' Giarrusso 4f0272415a [PATCH] uml: fix syscall stubs
Jeff Dike noted that the assembly code for syscall stubs is misassembled with
GCC 3.2.3: the values copied in registers weren't preserved between one asm()
and the following one.

So I fixed the thing by rewriting the __asm__ constraints more like unistd.h
ones.

Note: in syscall6 case I had to add one more instruction (i.e.  moving arg6 in
eax and shuffling things around) - it's needed for the function to be valid in
general (we can't load the value from the stack, relative to ebp, because we
change it), but could be avoided since we actually use a constant as param 6.

The only fix would be to turn stub_syscall6 to a macro and use a "i"
constraint for arg6 (i.e., specify it's a constant value).

Heiko Carstens a4c4af7c8d [PATCH] cpu hoptlug: avoid usage of smp_processor_id() in preemptible code
Replace smp_processor_id() with any_online_cpu(cpu_online_map) in order to
avoid lots of "BUG: using smp_processor_id() in preemptible [00000001]
code:..." messages in case taking a cpu online fails.

All the traces start at the last notifier_call_chain(...) in kernel/cpu.c.
Since we hold the cpu_control semaphore it shouldn't be any problem to access
cpu_online_map.

The reason why cpu_up failed is simply that the cpu that was supposed to be
taken online wasn't even there.  That is because on s390 we never know when a
new cpu comes and therefore cpu_possible_map consists of only ones and doesn't
reflect reality.

Zwane Mwaikambo 77f72b192f [PATCH] i386: LVT entries remaining unmasked on reboot
Excerpt from bugzilla entry

http://bugzilla.kernel.org/show_bug.cgi?id=5518

"i386 version of Reboot-through-BIOS is unsafe: it forgets to mask APIC LVT
interrupts before jumping to a BIOS entry point.  As a result, BIOS ends up
bombarded with interrupts early on boot.  The BIOS does not expect it since
following a "normal" hardware cpu reset, all APIC LVT registers have the
Mask bit (16) set and can't generate interrupts.

For example, the version of Phoenix BIOS used by VMware enables interrupts
for the first time before masking/clearing APIC LVT.  The APIC Timer LVT
register is still set up for a timer interrupt delivery with a high vector
from the previous Linux incarnation (0xef in our case).  The BIOS has not
fully initialized its IDT at this point and the real mode gate for 0xef
remains all zeros.  Vector 0xef dispatches BIOS to address 0:0, BIOS takes
a #GP and eventually hangs.

machine_shutdown() does attempt to shut down APIC before jumping to BIOS,
but it is ineffective"

SH7705 in extended cache mode has some left-over VALID_PAGE() cruft that it
checks when doing lazy dcache write-back.  This has been gone for some time

this also fixes up a build error in the non-discontig case).

pfn_valid() gives the desired behaviour, so we switch to that.

Paul Mundt 65463b73b1 [PATCH] sh: Drop hp690 discontig support
There was only one board using this (hp690 specifically), and it just so
happens that it's only physically discontiguous at the "normal" P1 offset.  If
we bump up the P1 offset, it's possible to hit a shadowed region of memory
where we suddenly become magically contiguous.

As people have been using this shadowed region workaround for quite some time
(and without any adverse effects), it's time to drop the left over discontig
bits that no longer have any practical use (it was always very much
hp690-centric to begin with).

Paul Mundt 055a251214 [PATCH] superhyway: multiple block support and VCR rework
This extends the API somewhat to allow for platform-specific VCR reading and
writing.  Some platforms (like SH4-202) implement the VCR in a split VCRL and
VCRH, but end up being in reverse order or have other quirks that need to be
dealt with, so we add a set of superhyway_ops per-bus to accomodate this.

We also have to extend the per-device resources somewhat, as some devices now
conveniently split control and data blocks.  So we allow a platform to
register its set of SuperHyway devices via superhyway_add_devices() with the
control block always ordered as the first resource (as this is the one that
userspace cares about).

John W. Linville 62afe595de [PATCH] 3c59x: convert to use of pci_iomap API
Convert 3c59x driver to use pci_iomap API.  This makes it easier to enable
the use of memory-mapped PCI I/O resources.

Manfred Spraul cd61ef6268 [PATCH] slab: Use same schedule timeout for all cpus in cache_reap
Chen noticed that cache_reap uses REAPTIMEOUT_CPUC+smp_processor_id() as
the timeout for rescheduling.

The "+smp_processor_id()" part is wrong, the timeout should be identical
for all cpus: start_cpu_timer already adds a cpu dependant offset to avoid
any clustering.

The attached patch removes smp_processor_id().

Pekka J Enberg 2109a2d1b1 [PATCH] mm: rename kmem_cache_s to kmem_cache
This patch renames struct kmem_cache_s to kmem_cache so we can start using
it instead of kmem_cache_t typedef.

Andrew Morton 4f12bb4f77 [PATCH] slab: don't BUG on duplicated cache
slab presently goes BUG if someone tries to register an already-registered
cache.

But this can happen if the user accidentally loads a module which is already
statically linked into the kernel.  Nuking the kernel is rather a harsh
reaction.

Change it into a warning, and just fail the kmem_cache_alloc() attempt.  If
the module is well-behaved, the modprobe will fail and all is well.

Notes:

- Swaps the ranking of cache_chain_sem and lock_cpu_hotplug().  Doesn't seem
  important.
