| | | * [ARM] Fix Versatile PB initialisation to use .init_machineRussell King2006-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no point having the Versatile PB initialisation using an arch_initcall() and then checking whether it's running on a Versatile PB board - this is what the .init_machine function pointer in the machine description is for. Use it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| | | * [ARM] 3911/2: Simplify alloc_thread_info on ARMPaul Gortmaker2006-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove ARM local cache of 4 struct thread_info. Can cause oops under certain circumstances. Russell indicated the original optimization was required on older kernels to avoid thread starvation on memory fragmentation, but may no longer be required. I've updated the patch to 19rc4 and ensured no <config.h> dain-bramage slipped in this time (sorry about that). Original description follows: I was given some test results which pointed to an Oops in alloc_thread_info (happened 2x), and after looking at the code, I see that ARM has its own local cache of 4 struct thread_info. There wasn't any clear (to me) synchronization between the alloc_thread_info and the free_thread_info. I looked over the other arch, and they all simply allocate them on an as needed basis, so I simplified the ARM to do the same, based on the other arch (e.g. PPC) and the folks doing the testing have indicated that this fixed the oops.

* | [PATCH] add rtc-omap driverDavid Brownell2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a new RTC-framework driver for the RTC/calendar module found in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree for several months now, and other trees before that, so it's quite stable. The most notable issue is that the OMAP IRQ code doesn't yet support the RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.

| | | | | | | | | | | | | | | | | show_mem() was not correctly handling holes in the memory map. It was treating the freed sections of the map as though they contained valid struct page entries. This could cause incorrect debugging output or even a kernel panic.

* [ARM] 3918/1: ixp4xx irq-chip reworkKevin Hilman2006-11-03
| | | | | | | | | | | | | | | | | This is a rework of the ixp4xx irq_chip implementation. The use of two irq_chip structures and potentially switching between them is a violation of the intended use of the IRQ framework. The current implementation does not work with current in-kernel spinlock debugging or lockdep due to lock recursion problems caused by calling set_irq_chip/handler from within the chip's set_irq_type(). This patch goes back to using one irq_chip structure and handling the differences between edge/level, normal/GPIO interrupts inside the ack/mask/unmask routines themselves.

* [ARM] 3912/1: Make PXA270 advertise HWCAP_IWMMXT capabilityPaul Gortmaker2006-11-02
| | | | | | | | | | | | | ARM patch 3756/1 added HWCAP_IWMMXT. This patch adds support for broadcasting that info via /proc/cpuinfo and sets it for the CPU features of the PXA270. I've booted 19rc3 on a pxa270 and confirmed that the /proc/cpuinfo shows "iwmmxt" in the Features.
