2005-07-06[PATCH] ARM: 2792/1: IXP4xx iomap API implementationDeepak Saxena
Patch from Deepak Saxena This patch implements the iomap API for Intel IXP4xx NPU systems. We need to implement our own version of the API functions b/c of the PCI hostbridge does not provide the capability to map PCI I/O space into the CPU's physical memory space. In addition, if a system has more than 64M of PCI memory mapped BARs, PCI memory must also be accessed indirectly. This patch changes the assignment of PCI I/O resources to fall into to 0x0000:0xffff range so that we can trap I/O areas in our ioread/iowrite macros.

2005-07-06[PATCH] ARM: 2789/1: Enable access to both CP10 and CP11 on ARMv6Catalin Marinas
Patch from Catalin Marinas The VFP instructions trigger undefined exceptions because the access to CP11 is disabled (only CP10 is currently enabled by the kernel). The patch fixes this problem.

2005-07-03[PATCH] ARM: 2784/1: Fix the block cache flush operation rangeCatalin Marinas
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 Aravamudan

2005-06-30[PATCH] ARM: 2778/1: Add -mno-thumb-interwork to CFLAGS_ABICatalin Marinas
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 King
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 Pitre
Patch from Nicolas Pitre Those are big, slow and generally not recommended for kernel code. They are even not present on i386.

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 King
Convert ARMs timer implementations to use readl/writel instead of accessing the registers via a struct.

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.

2005-06-27[PATCH] USB: omap_udc updates (mostly cleanups)David Brownell
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 King
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>

that don't need it 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 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.
