* [PATCH] x86_64: coding style and whitespace fixupsDomen Puncer2005-06-25
| | | | | | | | | | | Remove some of the unnecessary differences between arch/i386 and arch/x86_64. This patch fixes more whitespace issues, some miscellaneous typos, a wrong URL and a factually incorrect statement about the current boot sector code.

* [PATCH] char/ds1620: use msleep() instead of schedule_timeout()Domen Puncer2005-06-25
| | | | | | | | | | | | | | | | Not sure why any driver needs to sleep for *two* ticks, so let's fix it. Use msleep() instead of schedule_timeout() to guarantee the task delays as expected. Signals are never checked for by the callers or in the function itself, so use TASK_UNINTERRUPTIBLE instead of TASK_INTERRUPTIBLE. The delay is presumed to have been written when HZ==100, and thus has been multiplied by 10 to pass to msleep().

* [PATCH] kdump: Use real pt_regs from exceptionAlexander Nyberg2005-06-25
| | | | | | | | | | | | | | | | | | | | | Makes kexec_crashdump() take a pt_regs * as an argument. This allows to get exact register state at the point of the crash. If we come from direct panic assertion NULL will be passed and the current registers saved before crashdump. This hooks into two places: die(): check the conditions under which we will panic when calling do_exit and go there directly with the pt_regs that caused the fatal fault. die_nmi(): If we receive an NMI lockup while in the kernel use the pt_regs and go directly to crash_kexec(). We're probably nested up badly at this point so this might be the only chance to escape with proper information.

* [PATCH] kdump: KconfigVivek Goyal2005-06-25
| | | | | | | | | | | | - config option CONFIG_CRASH_DUMP - Made it dependent on HIGHMEM. This is required as capture kernel treats the previous kernel's memory as high memmory and stitches a PTE for accessing it.

* [PATCH] kdump: Retrieve saved max pfnVivek Goyal2005-06-25
| | | | | | | | | | | This patch retrieves the max_pfn being used by previous kernel and stores it in a safe location (saved_max_pfn) before it is overwritten due to user defined memory map. This pfn is used to make sure that user does not try to read the physical memory beyond saved_max_pfn.

* [PATCH] kdump documentation update to introduce use of irqpollVivek Goyal2005-06-25
| | | | | | | | | | | | | | o Specify "irqpoll" command line option which loading second kernel. This helps in reducing driver initialization failures in second kernel due to shared interrupts. o Enabled LAPIC/IOAPIC support for UP kernels in second kernel. This reduces the chances of devices sharing the irq and hence reduces the chances of driver initialization failures in second kernel. o Build a UP capture kernel and disabled SMP support.
