2006-12-01[ARM] 3958/1: add platform device (pxa2xx-udc)to ixp4xxMilan Svoboda
Create include/asm-arm/arch-ixp4xx/udc.h and add platfrom device ixp4xx_udc_device into arch/arm/mach-ixp4xx/common.c. This allows us to use pxa2xx-udc on the ixp4xx platfrom. Both pxa2xx and ixp4xx use the same device controller. Signed-off-by:Milan Svoboda <msvoboda@ra.rockwell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-12-01[ARM] 3965/1: ixp2000: fix handling of pci master abortsLennert Buytenhek
The master abort check in ixp2000_pci_read_config() recently started failing due to the compiler optimising out the read access following the clearing of pci_master_aborts. Mark pci_master_aborts volatile to force the compiler to reload it on every use. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-30[ARM] Fix Versatile PB initialisation to use .init_machineRussell King
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>
2006-11-30[ARM] 3911/2: Simplify alloc_thread_info on ARMPaul Gortmaker
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.

2006-11-30[ARM] 3940/1: don't reset PXA2xx clock counterNicolas Pitre
Don't reset OSCR to zero as this prevents us from having a contiguous time source. The value returned by sched_clock() is reset to zero in the middle of the boot process otherwise, making CONFIG_PRINTK_TIME rather messed up.

2006-11-30[ARM] Improve reliability of APM-emulation suspendRussell King
The APM emulation can sometimes cause suspend to fail to work due to apparantly waiting for some process to acknowledge an event when it actually has already done so. We re-jig the event handling to work around this behaviour. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-11-20[ARM] 3933/1: Source drivers/ata/KconfigMartin Michlmayr
ARM doesn't source drivers/Kconfig like most architectures do, so the newly added drivers/ata is currently not made available on ARM. SATA is used on some ARM machines, like the Thecus N2100, so we need to source drivers/ata/Kconfig.

2006-11-07[ARM] 3927/1: Allow show_mem() to work with holes in memory map.Ray Lehtiniemi
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. This patch keeps the struct meminfo around after system initialization so that show_mem() can use it when scanning memory. show_mem() now walks over each bank of each online node, rather than assuming that each node contains a single contiguous bank.

2006-11-07[ARM] 3926/1: make timer led handle HZ != 100David Brownell
The timer LED is unusable at HZ=large, since it's got a hard-wired value of 100 ticks per cycle; when HZ=1024 (for example) it's essentially always-on. This patch just makes that be HZ ticks per cycle. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-11-03[ARM] 3918/1: ixp4xx irq-chip reworkKevin Hilman
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.
