Ingo Molnar c9bc03ac31 Merge branch 'iommu-fixes-2.6.28' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/linux-2.6-iommu into x86/urgent 2008-12-18 13:28:11 +01:00
Bjorn Helgaas 55aab5f49e x86 gart: don't complain if no AMD GART found
Impact: remove annoying bootup printk

It's perfectly normal for no AMD GART to be present, e.g., if you have
Intel CPUs.  None of the other iommu_init() functions makes noise when
it finds nothing.

Takashi Iwai e28d83223a ALSA: hda - Fix silent HP output on D975
Some desktops seems to have no HP/mic jack detection on the front panel,
which results in the silent output in the recent driver, because the
driver mutes the output (to save power) when no plug is detected.

This patch adds a new model that disables the jack-detection.

Neil Horman 3e3d0e9246 PCI hotplug: ibmphp: Fix module ref count underflow
I happened to notice that the ibmphp hotplug driver does something
rather silly in its init routine.  It purposely calls module_put so as
to underflow its module ref count to avoid being removed from the
kernel.  This is bad practice, and wrong, since it provides a window for
subsequent module_gets to reset the refcount to zero, allowing an unload
to race in and cause all sorts of mysterious panics.  If the module is
unsafe to load, simply omitting the module_exit parameter is sufficient
to prevent the kernel from allowing the unload.

Samuel Ortiz 69c30e1e74 irda: Add irda_skb_cb qdisc related padding
We need to pad irda_skb_cb in order to keep it safe accross dev_queue_xmit()
calls. This is some ugly and temporary hack triggered by recent qisc code
changes.
Even though it fixes bugzilla.kernel.org bug #11795, it will be replaced by a
proper fix before 2.6.29 is released.

Alan Stern 24c0996a6b USB: skip Set-Interface(0) if already in altsetting 0
When a driver unbinds from an interface, usbcore always sends a
Set-Interface request to reinstall altsetting 0.  Unforunately, quite
a few devices have buggy firmware that crashes when it receives this
request.

To avoid such problems, this patch (as1180) arranges to send the
Set-Interface request only when the interface is not already in
altsetting 0.

This patch fixes a comment and clarifies the documentation about the
endianness of descriptors. The current policy is that descriptors will
be little-endian at the API even on big-endian systems; however the
/proc/bus/usb API predates this policy and presents descriptors with
some multibyte fields byte-swapped.

This patch will remove the section .note.gnu.build-id added in binutils
2.18 from the vmlinux.bin binary. Not removing this section results in a
huge multiple gigabyte binary and likewize large uImage.

Krzysztof Halasa e8e5752dc0 net: kernel BUG at drivers/net/phy/mdio_bus.c:165!
kernel BUG at drivers/net/phy/mdio_bus.c:165!
Unable to handle kernel NULL pointer dereference at virtual address 00000000

How?

mdiobus_alloc() sets bus->state = MDIOBUS_ALLOCATED.

mdiobus_register() sets bus->state = MDIOBUS_REGISTERED but then can
   fail (mdiobus_scan()) returning an error to the caller.

The caller aborts correctly with mdiobus_free() which does:
        if (bus->state == MDIOBUS_ALLOCATED) {
                kfree(bus);
                return;
        }

        BUG_ON(bus->state != MDIOBUS_UNREGISTERED);

David S. Miller 878a553595 sparc: We need to implement arch_ptrace_stop().
In order to always provide fully synchronized state to the debugger,
we might need to do a synchronize_user_stack().

A pair of hooks, arch_ptrace_stop_needed() and arch_ptrace_stop(),
exist to handle this kind of situation.  It was created for
the sake of IA64.

Use them, to flush the kernel side cached register windows
to the user stack, when necessary.

Andi Kleen cf9b303e55 x86: re-enable MCE on secondary CPUS after suspend/resume
Impact: fix disabled MCE after resume

Don't prevent multiple initialization of MCEs.

Back from early prehistory mcheck_init() has a reentry check. Presumably
that was needed in very old kernels to prevent it entering twice.

But as Andreas points out this prevents CPU hotplug (and therefore resume)
to correctly reinitialize MCEs when a AP boots again after being
offlined.

Just drop the check.

As noted by Julia Lawall <julia@diku.dk>, we can never
trigger the check for being in suspend due to the result
of !readl(i2c->regs + S3C2410_IICCON) & S3C2410_IICCON_IRQEN
always being 0.

Add suspend/resume hooks to stop i2c transactions happening

Mike Ditto a804644a1a i2c-cpm: Detect and report NAK right away instead of timing out
Make the driver report an ENXIO error immediately upon NAK instead of
waiting for another interrupt and getting a timeout.

When reading from a device that is not present or declines to respond
to, e.g., a non-existent register address, CPM immediately reports a
NAK condition in the TxBD, but the driver kept waiting until a timeout,
which takes 1 second and causes an ugly console error message.

James Bottomley a6da74cb07 [SCSI] mpt fusion: clear list of outstanding commands on host reset
A bug in the fusion driver was exposed by the switch to block timeout.
Basically, drivers are supposed to terminate commands once error
handling begins on them.  The fusion apparently wasn't doing this.
Under the old timeout regime, completions on terminated commands would
by and large get ignored because of the way command timeouts used to
work. The new block timers are very intolerant to this, though,
becuase the request gets cleaned and freed.
