2009-01-13hvc_console: Call free_irq() only if request_irq() was successfulMilton Miller
Only call free_irq if we marked the request_irq has having succeeded instead of whenever the the sub-driver identified the interrupt to use. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-01-13hvc_console: Change an mb() to smp_mb() and add some commentsMilton Miller
I remember some history on this barrier. There was a race between open via /dev/console and the tty being fully setup. Its also why there is a temporary variable and the global is assigned at the end of the function.

2009-01-13powerpc: Change u64/s64 to a long long integer typeIngo Molnar
Convert arch/powerpc/ over to long long based u64: -#ifdef __powerpc64__ -# include <asm-generic/int-l64.h> -#else -# include <asm-generic/int-ll64.h> -#endif +#include <asm-generic/int-ll64.h> This will avoid reoccuring spurious warnings in core kernel code that comes when people test on their own hardware. (i.e. x86 in ~98% of the cases) This is what x86 uses and it generally helps keep 64-bit code 32-bit clean too.

2009-01-13powerpc/kexec: Check crash_base for relocatable kernelMilton Miller
Enforce that the crash kernel region never overlaps the current kernel, as it will be written directly on kexec load. Also, default to the previous KDUMP_KERNELBASE if the start is 0. Other architectures (x86, ia64) state that specifying the start address 0 (or omitting it) will result in the kernel allocating it. Before the relocatable patch in 2.6.28, powerpc would adjust any other start value to the hardcoded KDUMP_KERNELBASE of 32M.

2009-01-13powerpc: Make dummy section a valid note headerMilton Miller
We are declaring the dummy section (used to work around a binutils bug) as PT_NOTE, but we don't have enough bytes for it to be a valid note header, and kexec userspace complains: Warning: Elf Note name is not null terminated Warning: append= option is not passed. Using the first kernel root partition Warning: Elf Note name is not null terminated Instead of using the arbitray value 0xf177 (aka "fill"), declare a no-name no-description note of type 0.

2009-01-12async: fix __lowest_in_progress()Arjan van de Ven
At 37000 feet somewhere near Greenland I woke up from a half-sleep with the realisation that __lowest_in_progress() is buggy. After landing I checked and there were indeed 2 problems with it; this patch fixes both: * The order of the list checks was wrong * The locking was not correct. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-01-12script: improve markup_oops.pl to also decode oopses in modulesArjan van de Ven
There has been some light flamewar on lkml about decoding oopses in modules (as part of the crashdump flamewar). Now this isn't rocket science, just the markup_oops.pl script cheaped out and didn't handle modules. But really; a flamewar all about that?? What happened to C++ in the kernel or reading files from inside the kernel? This patch adds module support to markup_oops.pl; it's not the most pretty perl but it works for my testcases...

2009-01-12ti_usb_3410_5052: support alternate firmwareChris Adams
The TI USB serial driver supports specifying alternate vendor and product IDs (since the chips can and are used in devices under other vendor/product IDs). However, the alternate IDs were not loaded in the combined product table. This patch also adds support for loading alternate firmware for alternate vendor/product IDs.

2009-01-12[WATCHDOG] Enable watchdog timer on GE Fanuc's SBC610Martyn Welch
Support for the FPGA based watchdog timer on GE Fanuc's SBC610. This patch enables one of the watchdog timers found on the SBC610. There are two identical watchdog timers at different offsets in the above mentioned boards, however the current driver is only capable of supporting one of them. The watchdog timers are also capable of generating interrupts at a user-configurable threshold, though support for this operation is currently not supported by the driver.
