This removes some nasty might_sleep() warnings. Worth fixing before 2.6.10-final IMO; we don't actually _know_ of oopses this bug caused ... The AX8817x link detection code was calling usb_submit_urb() with GFP_KERNEL in a completion handler (IRQ handler). That's a no-no. Signed-off-by:

please consider applying the attached patch which adds an identifier for another variant of the X10 RF remote. This one is very common everywhere in Europe where Aldi (a supermarket discounter) sells their PCs (Netherlands, Belgium, northern Germany, France, Spain, ...). Considering that they ship a few 100,000 PCs once or twice every year you can imagine there are quite a few of these remotes kicking around. I've tested with 2.6.10-rc2 and various versions of XMMS and lirc with the devinput driver. It does play well with lirc-0.7.0-pre8 but not so nice with 0.7.0. I don't know why, but according to some posts on the lirc list it seems to be in lirc. By the way, there seem to be even more variants of this device, according to: http://cvs.sourceforge.net/viewcvs.py/lirc/lirc/drivers/lirc_atiusb/lirc_atiusb.c From: Armijn Hemel <armijn@uulug.nl> Signed-off-by:

This adds "sparse -Wcontext" annotations to the main HCDs, reflecting that they all need to drop their (schedule) lock while issuing URB completion callbacks. (Some completion callbacks will resubmit that URB, relying on that to keep the endpoint queue from emptying and getting descheduled.) Signed-off-by:

This would be rare with HCDs that maintain chains of DMA transfers, except if the HC dies in the middle of an I/O request; so no rush to merge this. It'd happen in a PIO based HCD though ... :) Async unlink of an URB from an endpoint's I/O queue _normally_ involves a delay from handshaking with the host controller, to be sure the DMA queue is inactive. So urb->complete() runs after usb_unlink_urb() returns, and from a different context. But not always... The completion may run immediately whenever the HCD knows that HC isn't busy with the URB. Maybe that HCD is in a HALT state, or the endpoint queue is is temporarily off-schedule (halted, or dead after PM resume from D3cold, etc) ... or maybe the HCD doesn't use DMA, so most unlinks just list_del_init() and return. This makes usb_sg_cancel() and sg_complete() drop the io->lock when they cancel active urbs, preventing potential self-deadlock when that completion handler runs immediately. Signed-off-by:

This has two minor patches to make this driver work better with the Genesys GL880S: don't report hardware port indicators (until the root hub code supports them); and patch the misreported number of ports (two, not four). Signed-off-by:

The UDC in Intel's "Bulverde" processors is incompatible with the one in their PXA 25x/26x/21x processors, and has different sorts of restrictions. For example, it can implement real CDC Ethernet, while the earlier (PXA 25x etc) can't. This adds a gadget_is_pxa27x() function and uses it appropriately in the current set of gadget drivers. (And moves an LH7A40X entry to the right place in "ether.c"). From: Dmitry Krivoschokov <dkrivoschokov@dev.rtsoft.ru> Signed-off-by:

Len Brown convinced me that the problem with disabling PCI routing entries wasn't the disable as much as the fact that ELCR needs to be updated when removing the PCI routing. So this reverts the previous cset and updates ELCR as suggested by Len.

Ignore offline CPUs when registering IOSAPIC interrupts. We previously directed interrupts even to offline CPUs, which means that if you have some unused CPUs (e.g., you used "maxcpus="), some interrupts won't work. This really hurts because distro installs typically use "maxcpus=1". Patch by Alex Williamson. Signed-off-by:

This fixes at least some interrupt polarity setup cases. The ACPI guys may want to eventually do this differently, but in the meantime this makes ACPI behaviour closer to non-ACPI behaviour, and fixes known problems. I'll further argue that this protects non-PCI devices that may just share the irq routing from being screwed, but that may or may not be an argument that everybody buys into.

This depends on the previous ptrace single-step cleanup, and makes sure that signal handling does not lose TF events. This allows debuggers to trace programs that set TF on their own.

(This makes the naming of "DTRACE" purely historical, since on x86 it now means "single step in progress").

We just spent some days fighting a rare race in one of the distro's who backported some of timer.c from 2.6 to 2.4 (though they missed a bit). The actual race we found didn't happen in 2.6 _but_ code inspection showed that a similar race is still present in 2.6, explanation below: Code removing a timer from a list (run_timers or del_timer) takes that CPU list lock, does list_del, then timer->base = NULL. It is mandatory that this timer->base = NULL is visible to other CPUs only after the list_del() is complete. If not, then mod timer could see it NULL, thus take it's own CPU list lock and not the one for the CPU the timer was beeing removed from the list, and thus the list_add in mod_timer() could race with the list_del() from run_timers() or del_timer(). Our race happened with run_timers(), which _DOES_ contain a proper smp_wmb() in the right spot in 2.6, but didn't in the "backport" we were fighting with. However, del_timer() doesn't have such a barrier, and thus is subject to this race in 2.6 as well. This patch fixes it. Signed-off-by:

The "udbg" code used on ppc64 for early consoles including early serial console recently got a new "default speed" option. This was implemented as a switch case that missed a few important cases, one beeing necessary for a board beeing released soon. This patch fixes it by using the proper division to calculate the dll value for the uart instead of that bogus switch/case. Signed-off-by:

The pci_bus_to_host() inline function used on ppc64 to find the pci_contoller structure a give pci_bus resides on used to contain bogus tree walking code, which fortunately ended up never beeing necessary since "sysdata" always points to a device_node structure that has the proper "phb" field (even if it is not the device-node of the actual P2P, which happens during boot).

The ppc64 kernel can be built with a default command line (CONFIG_CMDLINE) for cases where none is provided by the firmware. However, some OF implementation always pass a "bootargs" property that only contains the "0" terminating byte of a C string which caused us to think there was a command line, and not use the built-in one.

ChangeSet "adaplas: [PATCH] fbdev: Add __iomem annotations to hgafb" had actually broken it - it not only added a (useless) cast in rowaddr(), it had also added a dereferencing. Since it is video memory and since we do memory transfers on the resulting "address"... IOW, it's even exploitable - not that there had been a lot of HGA boxen out there, but... This restores the intended behaviour. Signed-off-by:
