e5c34a57c8 [PATCH] Fix typo in x86_64 __build_write_lock_const assembly
Based on __build_read_lock_const, this looked like a bug.

c660439ba9 [PATCH] x86_64/ia64 : Fix compilation error for node_to_first_cpu
Fixes a compiler error in node_to_first_cpu, __ffs expects unsigned long as
a parameter; instead cpumask_t was being passed.  The macro
node_to_first_cpu was not yet used in x86_64 and ia64 arches, and so we never
hit this.  This patch replaces __ffs with first_cpu macro, similar to other
arches.

1836098f97 [PATCH] forcedeth: fix random memory scribbling bug
Two critical bugs were found in forcedeth 0.47:
 - TSO doesn't work.
 - pci_map_single() for the rx buffers is called with size==0.  This bug
   is critical, it causes random memory corruptions on systems with an
   iommu.

Below is a minimal fix for both bugs, for 2.6.15.

TSO will be fixed properly in the next version.  Tested on x86-64.

d2b1839425 [MMC] Set correct capacity for 1024-byte block cards
We were passing set_capacity() the capacity we calculated in terms of
the number of blocks on the card, which happened to be the right units
for 512-byte block cards.  However, with 1024-byte block cards, we
end up setting the capacity to half the number of blocks.  Fix this
by shifting by the appropriate amount.

Thanks to Todd Blumer for pointing this out.

Use get_capacity() to report the card capacity, rather than
recalculating it from the CSD information.

Finally, use our chosen IO block size for the SET_BLOCKLEN command
rather than the CSD read block size.  Currently these are equivalent,
but will not be in the future.

d6f029130f [PATCH] fix race with preempt_enable()
Currently a simple

	void foo(void) { preempt_enable(); }

produces the following code on ARM:

foo:
	bic	r3, sp, #8128
	bic	r3, r3, #63
	ldr	r2, [r3, #4]
	ldr	r1, [r3, #0]
	sub	r2, r2, #1
	tst	r1, #4
	str	r2, [r3, #4]
	blne	preempt_schedule
	mov	pc, lr

The problem is that the TIF_NEED_RESCHED flag is loaded _before_ the
preemption count is stored back, hence any interrupt coming within that
3 instruction window causing TIF_NEED_RESCHED to be set won't be
seen and scheduling won't happen as it should.

Nothing currently prevents gcc from performing that reordering.  There
is already a barrier() before the decrement of the preemption count, but
another one is needed between this and the TIF_NEED_RESCHED flag test
for proper code ordering.

9b78a82c1c [IPSEC]: Fix policy updates missed by sockets
The problem is that when new policies are inserted, sockets do not see
the update (but all new route lookups do).

This bug is related to the SA insertion stale route issue solved
recently, and this policy visibility problem can be fixed in a similar
way.

The fix is to flush out the bundles of all policies deeper than the
policy being inserted.  Consider beginning state of "outgoing"
direction policy list:

	policy A --> policy B --> policy C --> policy D

First, realize that inserting a policy into a list only potentially
changes IPSEC routes for that direction.  Therefore we need not bother
considering the policies for other directions.  We need only consider
the existing policies in the list we are doing the inserting.

Consider new policy "B'", inserted after B.

	policy A --> policy B --> policy B' --> policy C --> policy D

Two rules:

1) If policy A or policy B matched before the insertion, they
   appear before B' and thus would still match after inserting
   B'

2) Policy C and D, now "shadowed" and after policy B', potentially
   contain stale routes because policy B' might be selected
   instead of them.

Therefore we only need flush routes assosciated with policies
appearing after a newly inserted policy, if any.

8b1af56b29 powerpc: Fix i8259 cascade on pSeries with XICS interrupt controller
It turns out that commit f9bd170a87
broke the cascade from XICS to i8259 on pSeries machines; specifically
we ended up not ever doing the EOI on the XICS for the cascade.  The
result was that interrupts from the serial ports (and presumably any
other devices using ISA interrupts) didn't get through.  This fixes
it and also simplifies the code, by doing the EOI on the XICS in the
xics_get_irq routine after reading and acking the interrupt on the
i8259.

1d1428045c [IPV6]: Fix address deletion
If you add more than one IPv6 address belonging to the same prefix and 
delete the address that was last added, routing table entry for that 
prefix is also deleted.
Tested on 2.6.14.4

To reproduce:
ip addr add 3ffe::1/64 dev eth0
ip addr add 3ffe::2/64 dev eth0
/* wait DAD */
sleep 1
ip addr del 3ffe::2/64 dev eth0
ip -6 route

(route to 3ffe::/64 should be gone)

In ipv6_del_addr(), if ifa == ifp, we set ifa->if_next to NULL, and later 
assign ifap = &ifa->if_next, effectively terminating the for-loop.
This prevents us from checking if there are other addresses using the same 
prefix that are valid, and thus resulting in deletion of the prefix.
This applies only if the first entry in idev->addr_list is the address to 
be deleted.

28120be5d6 [PATCH] USB Storage: Force starget->scsi_level in usb-storage scsiglue.c
When the usb-storage module forces sdev->scsi_level to SCSI_2, it should
also force starget->scsi_level to the same value.  Otherwise, the SCSI
layer may attempt to issue SCSI-3 commands to the device, such as REPORT
LUNS, which it cannot handle.  This can prevent the device from working
with Linux.

The AMS Venus DS3 DS2316SU2S SATA-to-SATA+USB enclosure, based on the
Oxford Semiconductor OXU921S chip, requires this patch to function
correctly on Linux.  The enclosure reports a SCSI-3 SPC-2 command set
level, but does not correctly handle the REPORT LUNS SCSI command -
probably due to a bug in its firmware.

It seems likely that other USB storage enclosures with similar bugs will
also benefit from this patch.

Tony Lindgren <tony@atomide.com> collaborated in the development of this
patch.

Jan's crosscompile page [1] shows, that one regression in 2.6.15-rc is
that the v850 defconfig does no longer compile.

The compile error is:

In file included from /usr/src/ctest/rc/kernel/arch/v850/kernel/setup.c:17:

make[2]: *** [arch/v850/kernel/setup.o] Error 1

The #include <asm/smp.h> in irq.h was intruduced in 2.6.15-rc.

Since include/linux/irq.h needs code from asm/smp.h only in the
CONFIG_SMP=y case and linux/smp.h #include's asm/smp.h only in the
CONFIG_SMP=y case, I'm suggesting this patch to #include <linux/smp.h>
in irq.h.

I've tested the compilation with both CONFIG_SMP=y and CONFIG_SMP=n
