2006-11-17x86: be more careful when walking back the frame pointer chainLinus Torvalds
When showing the stack backtrace, make sure that we never accept not only an unchanging frame pointer, but also a frame pointer that moves back down the stack frame. It must always grow up (toward older stack frames). I doubt this has triggered, but a subtly corrupt stack with extremely unlucky contents could cause us to loop forever on a bogus endless frame pointer chain. This review was triggered by much worse problems happening in some of the other stack unwinding code. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-11-17[PATCH] i386/x86_64: ACPI cpu_idle_wait() fixIngo Molnar
The scheduler on Andreas Friedrich's hyperthreading system stopped working properly: the scheduler would never move tasks to another CPU! The lask known working kernel was 2.6.8. After a couple of attempts to corner the bug, the following smoking gun was found: BIOS reported wrong ACPI idfor the processor CPU#1: set_cpus_allowed(), swapper:1, 3 -> 2 [<c0103bbe>] show_trace_log_lvl+0x34/0x4a [<c0103ceb>] show_trace+0x2c/0x2e [<c01045f8>] dump_stack+0x2b/0x2d [<c0116a77>] set_cpus_allowed+0x52/0xec [<c0101d86>] cpu_idle_wait+0x2e/0x100 [<c0259c57>] acpi_processor_power_exit+0x45/0x58 [<c0259752>] acpi_processor_remove+0x46/0xea [<c025c6fb>] acpi_start_single_object+0x47/0x54 [<c025cee5>] acpi_bus_register_driver+0xa4/0xd3 [<c04ab2d7>] acpi_processor_init+0x57/0x77 [<c01004d7>] init+0x146/0x2fd [<c0103a87>] kernel_thread_helper+0x7/0x10 a quick look at cpu_idle_wait() shows how broken that code is on i386: it changes the init task's affinity map but never restores it ... and because all userspace tasks get forked by init, they all inherited that single-CPU affinity mask. x86_64 cloned this bug too.

The fix is to align the stack pointer.

2006-11-16Fix generic fb_ddc i2c edid probe msgLinus Torvalds
Benh points out that the msgs[0].flags entry never got initialized, and since it's an automatic stack allocation, it could have any random value, which is bad. Rewrite the initializer to explicitly initialize all fields of the small i2c_msg structure array we generate. Just to keep it all obvious, let's handle msgs[1].buf in the same initializer while we're at it, instead of initializing that one separately later. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-11-16USB: correct keymapping on Powerbook built-in USB ISO keyboardsOlaf Hering
similar to the version in adbhid_input_register(): The '<>' key and the '^°' key on a german keyboard is swapped. Provide correct keys to userland, external USB keyboards will not work correctly when the 'badmap'/'goodmap' workarounds from xkeyboard-config are used. It is expected that distributions drop the badmap/goodmap part from keycodes/macintosh in the xkeyboard-config package. This is probably 2.6.18.x material, if major distros settle on 2.6.18.

The root cause is that some irq_chip variables, especially ia64_msi_chip, initiate their memeber end to point to NULL. __do_IRQ doesn't check if irq_chip->end is null and just calls it after processing the interrupt. As irq_chip->end is called at many places, so I fix it by reinitiating irq_chip->end to dummy_irq_chip.end, e.g., a noop function.

If the device is allocated dynamically by platform_device_alloc, platform_device_alloc will initialize struct device, then, platform_device_add should be used to register the device. The difference between platform_device_register and platform_device_add is platform_device_register will initiate the device while platform_device_add won't.
