[PATCH] alpha: SMP IRQ routing fix
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>
After removal of fixup_cpu_present_map() function Alpha ended up with an empty
cpu_present_map, so secondary CPUs on SMP systems are not being started.
Worse, on some platforms we route interrupts to secondary CPUs using
cpu_possible_map which is still populated properly. As a result, these
interrupts go nowhere so the machines like DP264 aren't able to boot even with
a primary CPU.
Fixed basically by s/cpu_present_mask/cpu_present_map/.
Thanks to Ernst Herzberg for reporting the bug and testing the fix.

On the ixp23xx, the microengine thread interrupt sources are numbered
56..119, but their mask/status bits are located in bit positions 64..127
in the various registers in the interrupt controller (bit positions
56..63 are unused.)
We don't deal with this, so currently, when asked to enable IRQ 64, we
will enable IRQ 56 instead.
The only interrupts >= 64 are the thread interrupt sources, and there
are no in-tree users of those yet, so this is fortunately not a big
problem, but this needs fixing anyway.

[ARM] 3539/1: ixp23xx: fix __arch_ixp23xx_is_coherent() for A1 stepping
Patch from Lennert Buytenhek
The current __ixp23xx_arch_is_coherent() check assumes that the
lower byte of IXP23XX_PRODUCT_ID is identical to the lower byte of
processor_id, but this is not the case, and because of this we were
incorrectly enabling coherency on A1 stepping CPUs.
Stepping A1 of the ixp2350, which has a PRODUCT_ID of 0x401, has '02'
in the lower byte of processor_id, while A2, with a PRODUCT_ID of
0x402, has '04' in the lower byte of processor_id.
So, to check for >= A2, we really need to check the lower byte of
processor_id against >= 4.

is in total disconnect with the condition that makes use of it:
/* More than offslab_limit objects will cause problems */
if ((flags & CFLGS_OFF_SLAB) && num > offslab_limit)
break;
but due to offslab_limit being a global variable this breakage was
hidden.
Up until lockdep came along and perturbed the slab sizes sufficiently so
that the first off-slab cache would still see a (non-calculated) zero
value for offslab_limit and would panic with:
Kernel panic - not syncing: kmem_cache_create(): failed to create slab `size-512'
Paolo Ornati's config on x86_64 managed to trigger it.
The fix is to move the calculation to the place that makes use of it.
This also makes slab.o 54 bytes smaller.
Btw., the check itself is quite silly. Its intention is to test whether
the number of objects per slab would be higher than the number of slab
control pointers possible. In theory it could be triggered: if someone
tried to allocate 4-byte objects cache and explicitly requested with
CFLGS_OFF_SLAB. So i kept the check.
Out of historic interest i checked how old this bug was and it's
ancient, 10 years old! It is the oldest hidden and then truly triggering
bugs i ever saw being fixed in the kernel!

calls sysfs_notify. However sysfs_notify grabs a mutex and so cannot be
called in interrupt context.
This patch just creates a variant of md_new_event which avoids the sysfs
call, and uses that. A better fix for later is to arrange for the event to
be called from user-context.
Note: avoiding the sysfs call isn't a problem as an error will not, by
itself, modify the sync_action attribute. (We do still need to

[PATCH] x86_64: Handle empty node zero
From: Daniel Yeisley <dan.yeisley@unisys.com>
It is possible to boot a Unisys ES7000 with CPUs from multiple cells, and not
also include the memory from those cells. This can create a scenario where
node 0 has cpus, but no associated memory. The system will boot fine in a
configuration where node 0 has memory, but nodes 2 and 3 do not.
[AK: I rechecked the code and generic code seems to indeed handle that already.
Dan's original patch had a change for mm/slab.c that seems to be already in now.]

[PATCH] x86_64: fix last_tsc calculation of PM timer
From: "Jan Beulich" <jbeulich@novell.com>
The PM timer code updates vxtime.last_tsc, but this update was done
incorrectly in two ways:
- offset_delay being in microseconds requires multiplying with cpu_mhz
rather than cpu_khz
- the multiplication of offset_delay and cpu_khz (both being 32-bit
values) on most current CPUs would overflow (observed value of the
delay was approximately 4000us, yielding an overflow for frequencies
starting a little above 1GHz)

When using apic= on the kernel command line, this had no effect for machines
matched by either the ACPI MADT or the MPS OEM table scan. However, when such

[CIFS] ACPI suspend oops
Wasn't able to reproduce a hard hang, but was able to get an oops if
suspended the machine during a copy to the cifs mount. This led to some
things hanging, including a "sync". Also got I/O errors when trying to
access the mount afterwards (even when didn't see the oops), and had
to unmount and remount in order to access the filesystem.
This patch fixed the oops.

[PATCH] s390: lcs driver bug fixes and improvements [1/2]
Several problems occured with lcs device driver:
- device not operational anymore after cable pull/plug-in.
- unpredictable results occured, e.g. kernel panic
using cards of type QD8F.
- STOPLAN and delete multicast address command
were not proper recognized by OSA card under heavy network workload.
- channel/device error checks missing in interrupt handler.
To fix all problems at once recovery of lcs devices has been improved.
missing error checks in lcs interrupt handler has been added.
Once a hardware problem occurs lcs will recover the device now properly.

Problem only occured when qeth was built without IPV6 support.
- avoid skb usage after invocation of qeth_flush_buffers,
because skb might already be freed.
- remove yet another useless netif_wake_queue in
qeth_softsetup_ipv6 since this function is only called
when device is going online. In this case card->state will
never be in state UP. So let the net_device queue down .

During a code scan for another change I discovered that this call to
pcnet32_free_ring must be removed. If the open fails due to a lack of
memory all the ring structures are removed via the call to free_ring
and a subsequent call to open will dereference a null pointer in
pcnet32_init_ring.
Please apply to 2.6.17.
