These didn't match my sed expression correctly, fix them up manually. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-07-03[PATCH] ARM: 2784/1: Fix the block cache flush operation rangeCatalin Marinas1-1/+2
Patch from Catalin Marinas The range for the ARMv6 block cache operations is inclusive but the kernel doesn't re-calculate the end address, causing a page fault when used (this only happens with support for cache aliasing, otherwise the blk_flush_kern_dcache_page() is not called). This patch subtracts L1_CACHE_BYTES from the end address. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-07-01[PATCH] ARM: replace schedule_timeout() with msleep()Nishanth Aravamudan1-2/+1
Use msleep() instead of schedule_timeout() to guarantee the task delays as expected. Neither signals nor wait-queue events are important at this point in the code, I believe.

Patch from Ben Dooks The omnimeter_defconfig does not define any machines and seems to have no other support in the current kernel.

Patch from Todd Poynor Add support for PXA27x Standby mode, a low-power mode that retains CPU and some peripheral state (the existing "sleep" mode is a power-power mode that retains less state).

Patch from Catalin Marinas This patch fixes the V bit setting for the ARM1020x processors. At reset, this bit is automatically set to the value of the HIVECSINIT input signal which just happened to be 1 but it is not mandatory.

2005-06-30[PATCH] ARM: 2778/1: Add -mno-thumb-interwork to CFLAGS_ABICatalin Marinas1-1/+1
Patch from Catalin Marinas The new EABI gcc adds -mthumb-interwork by default, even if -mabi=apcs-gnu is passed. This causes a warning for every compiled C file when -march=armv4 is used. The patch adds -mno-thumb-interwork if the option is supported. This is also useful since we don't need any ARM/Thumb interworking in the kernel Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-06-30[PATCH] ARM: Don't try to send a signal to pid0Russell King2-45/+42
If we receive an unrecognised abort during boot, don't try to send a signal to pid0, but instead report the current state. This leads to less confusing debug reports. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-06-29[PATCH] ARM: 2723/2: remove __udivdi3 and __umoddi3 from the kernelNicolas Pitre4-412/+1
Patch from Nicolas Pitre Those are big, slow and generally not recommended for kernel code. They are even not present on i386.

2005-06-29[PATCH] ARM: 2769/1: cpu_init() stack setup fixCatalin Marinas1-1/+2
Patch from Catalin Marinas The compiler allocates r14 for the stk variable in the __asm__ directive. This is a shadowed register and gets changed when the mode is changed, causing random values in the SP register. The patch adds a clobber for the r14 register.

2005-06-29[PATCH] ARM: Convert ARM timer implementations to use readl/writelRussell King2-65/+38
Convert ARMs timer implementations to use readl/writel instead of accessing the registers via a struct.

2005-06-28[PATCH] ARM: 2760/1: Add a warning on dynamic tick timekeeping on some platformsTony Lindgren1-0/+5
Patch from Tony Lindgren This patch was suggested by RMK, and adds a warning on the accuracy of timekeeping when using dynamic tick on some platforms. Depending on the timer implementation, dynamic tick may affect the accuracy of timekeeping. Currently at least OMAP is known to have accurate timekeeping with dynamic tick.

2005-06-27[PATCH] USB: omap_udc updates (mostly cleanups)David Brownell1-4/+4
Various USB patches, mostly for portability: - Fifo mode 1 didn't work previously (oopsed), so now it's fixed and (why not) defines even more endpoints for composite devices. - OMAP 1710 doesn't have an internal transceiver. - Small PM update: if the USB link is suspended, don't disconnect on entry to deep sleep. - Be more correct about handling zero length control reads. OMAP seems to mis-handle that protocol peculiarity though; best avoided. - Platform device resources (for UDC and OTG controllers) now use physical addresses, so /proc/iomem is more consistent. - Minor cleanups, notably (by volume) for "sparse" NULL warnings.

2005-06-25[PATCH] ARM: Generic Dynamic Tick Timer support for ARM, take 4Russell King3-0/+132
This patch adds support for Dynamic Tick Timer for ARM. Dynamic Tick is also known as VST (Variable Scheduling Timeouts). Dynamic Tick has been in use in the OMAP tree since last October. The patch is not intrusive, and does not do anything unless CONFIG_NO_IDLE_HZ is defined. This patch has the following fixed based on comments from RMK: - Time is updated before calling interrupt handlers. - Added new interrupt flag SA_TIMER to avoid duplicate timer interrupts - Moved struct dyn_tick_timer to time.h until we at some point probably have an arch independent dyn-tick.h - Cleaned up testing for DYN_TICK_ENABLED in irq.c I've cleaned up this patch to fix some remaining issues: - Call the timer tick handler with irqs disabled, as it would be from a normal interrupt - if we have a dyn_tick, we better implement all methods. - generic timer_dyn_reprogram() call, to be called before sleeping - added command line option - "dyntick=" to allow boot-time control of this feature -- rmk Signed-off-by: Tony Lindgren Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-25[PATCH] ARM: 2752/1: disable ixp2000 PCI I/O software workaround on chips that don't need itLennert Buytenhek7-0/+26
Patch from Lennert Buytenhek The later ixp2000 models don't need the PCI I/O workaround that we currently perform. Add a config option to disable the workaround, and panic on boot if a kernel without the workaround is booted on a buggy chip. As only pre-production ixp2000s need the workaround, the default is for it not to be configured in.

Patch from Lennert Buytenhek The ixp2000 gpio cleanup broke the ixdp2800 build as it moved some gpio-related functions from arch/platform.h to arch/gpio.h and the ixdp2x00 support code used those functions but didn't include the latter header file.

2005-06-24[PATCH] ARM: 2698/1: Enable kernel r/w access to user pages on ARMv6Catalin Marinas1-3/+3
Patch from Catalin Marinas cpu_v6_set_pte() sets the kernel access rights to r/o for user pages (L_PTE_USER) when neither L_PTE_WRITE nor L_PTE_DIRTY are set. This causes a kernel data abort when writing the TLS value in the 0xffff0000 page. This patch enables the kernel r/w access.
