ACPI: thinkpad-acpi: change thinkpad-acpi input default and kconfig help
The current kconfig help text was misleading users. Also, the default for
an input-layer-optimized support caused way too many problems without
up-to-date userspace in place.
So, rework the help text, and change the default to N. Note that
distributions are supposed to enable this option as soon as they update HAL
to a version that handles the thinkpad-acpi new input layer interface.

genirq: temporary fix for level-triggered IRQ resend
Marcin Slusarz reported a ne2k-pci "hung network interface" regression.
delayed disable relies on the ability to re-trigger the interrupt in the
case that a real interrupt happens after the software disable was set.
In this case we actually disable the interrupt on the hardware level
_after_ it occurred.
On enable_irq, we need to re-trigger the interrupt. On i386 this relies
on a hardware resend mechanism (send_IPI_self()).
Actually we only need the resend for edge type interrupts. Level type
interrupts come back once enable_irq() re-enables the interrupt line.
I assume that the interrupt in question is level triggered because it is
shared and above the legacy irqs 0-15:
17: 12 IO-APIC-fasteoi eth1, eth0
Looking into the IO_APIC code, the resend via send_IPI_self() happens
unconditionally. So the resend is done for level and edge interrupts.
This makes the problem more mysterious.
The code in question lib8390.c does
disable_irq();
fiddle_with_the_network_card_hardware()
enable_irq();
The fiddle_with_the_network_card_hardware() might cause interrupts,
which are cleared in the same code path again,
Marcin found that when he disables the irq line on the hardware level
(removing the delayed disable) the card is kept alive.
So the difference is that we can get a resend on enable_irq, when an
interrupt happens during the time, where we are in the disabled region.

Make sure to reduce the rating of the ITC clock if ITCs are drifty. If they

arbitrarily).
Without this patch it is possible that the ITC clock becomes selected as

Fix WARN_ON() on bitfield ops
Alexey Dobriyan noticed that the new WARN_ON() semantics that were
introduced by commit
684f978347deb42d180373ac4c427f82ef963171 (to also
return the value to be warned on) didn't compile when given a bitfield,
because the typeof doesn't work for bitfields.
So instead of the typeof trick, use an "int" variable together with a
"!!(x)" expression, as suggested by Al Viro.
To make matters more interesting, Paul Mackerras points out that that is
sub-optimal on Power, but the old asm-coded comparison seems to be buggy
anyway on 32-bit Power if the conditional was 64-bit, so I think there
are more problems there.
Regardless, the new WARN_ON() semantics may have been a bad idea. But
this at least avoids the more serious complications.

- Move validation logic for SPI chipselects to spi_new_device(),

- In spi_new_device(), emit error messages if the device can't
be created. This is LOTS better than a silent failure; though
eventually, the calling convention should probably change to
use the <linux/err.h> conventions.
- Includes one previously-missing check: SPI masters must always

into 32-bit unsigned but not into 32-bit signed integer properly. Target

Change local variable tid to u32 so the whole expression is of u32 type and

UDF: fix UID and GID mount option ignorance
This patch fix weird behaviour of UDF mounting procedure. To get UID
changed (for now) we have to type
mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point
and specifying two uid at once is strange a bit. So with the patch we are
able to mount without additional 'uid=ignore' option. The same for GID
option is done.
This patch will not break current mount scheme (with two option).
Btw this does fix (I hope) the following

Fix a use after free bug in kernel->userspace relay file support
Coverity spotted what looks like a real possible case of using a variable
after it has been freed. The problem is in
kernel/relay.c::relay_open_buf()
If the code hits "goto free_buf;" it ends up in this code :
free_buf:
relay_destroy_buf(buf); <--- calls kfree() on 'buf'.
free_name:
kfree(tmpname);
end:
return buf; <-- use after free of 'buf'.
I read through the callers and they all handle a NULL return from this
function as an error (and hitting the 'free_buf' label only happens on
failure to chan->cb->create_buf_file(), so that looks like a clear error to
me).
The patch simply sets 'buf' to NULL after the call to
relay_destroy_buf(buf); - as far as I can see that should take care of the
problem.
The patch also corrects a reference to a documentation file while
I was at it.
Note from Mathieu: the documentation reference change should have been
done in a separate patch, but I guess no one will really care.
