It's definition is wrong (-1 means "no limit" not 999),
only the Sparc SunOS/Solaris compat code uses it, so
let's just kill it off completely from limits.h and
all referencing code.

Return logic was inverted.
Going for changing the return value to not return zero as it is makes
more sense regarding the naming of the function (cpu_has_cpufreq()).

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.

NFS client prevents mandatory lock, but there is a flaw on it; Locks are
possibly left if the mode is changed while locking.
This permits unlocking even if the mandatory lock bits are set.

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.

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.

It turns out that commit f9bd170a87948a9e077149b70fb192c563770fdf
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.

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.

When compiled-in, make sure the sound system has initialized
before these drivers do.
Reported by Adrian Bunk <bunk@stusta.de>
(The right fix would be to make the sound core use "subsys_initcall()"
and thus initialize before all normal drivers, but this is the quick
and limited safe fix for 2.6.15).

This patch (as618) changes usbcore to prevent derailing the
suspend/resume sequence when a USB driver doesn't include support for
it. This is a workaround rather than a true fix; the core needs to be
changed so that URB submissions from suspended drivers can be refused
and outstanding URBs cancelled.

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.

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:
<-- snip -->
...
CC arch/v850/kernel/setup.o
In file included from /usr/src/ctest/rc/kernel/arch/v850/kernel/setup.c:17:
/usr/src/ctest/rc/kernel/include/linux/irq.h:13:43: asm/smp.h: No such file or directory
make[2]: *** [arch/v850/kernel/setup.o] Error 1
<-- snip -->
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
on i386.

There's currently a diagnostic printk in relay_switch_subbuf() meant as
a warning if you accidentally try to log an event larger than the
sub-buffer size.
The problem is if this happens while logging from somewhere it's not
safe to be doing printks, such as in the scheduler, you can end up with
a deadlock. This patch removes the warning from relay_switch_subbuf()
and instead prints some diagnostic info when the channel is closed.
Thanks to Mathieu Desnoyers for pointing out the problem and
suggesting a fix.

It was a stupid workaround for the "static inline" vs.
"extern inline" issues of long ago, and it is what causes
schedule() to be inlined like crazy into kernel/sched.c
when -Os is specified.
MIPS and S390 should probably do the same.
Now CC_OPTIMIZE_FOR_SIZE can be safely used on sparc64
once more.

When a spinlock debugging check hits, we print the CPU number as an
informational thing - but there is no guarantee that preemption is off
at that point - hence we should use raw_smp_processor_id(). Otherwise
DEBUG_PREEMPT will print a warning.
With this fix the warning goes away and only the spinlock-debugging info
is printed.

The overflow checking condition in lib/swiotlb.c was wrong.
It would first run a NULL pointer through virt_to_phys before
testing it. Since pci_map_sg overflow is not that uncommon
and causes data corruption (including broken file systems) when not
properly detected I think it's better to fix it in 2.6.15.
This affects x86-64 and IA64.

Whenever ywrap scrolling is selected together with 180 degree screen
rotation, 2.6.15-rc6 and earlier versions are broken. fb_pan_display()
expects non-negative yoffsets, but ud_update_start() calls it with
yoffsets down to -(yres - font height). This patch transforms yoffset
to the correct range 0 ... vyres-1.
Some obviously unneeded parentheses are removed, too.
Verified with cyblafb, should be applied before 2.6.15-final because it
does fix the framebuffer rotation code introduced early in the 2.6.15
release cycle.
