2006-03-12[ARM] iwmmxt thread state alignmentRussell King
This patch removes the reliance of iwmmxt on hand coded alignments. Since thread_info is always 8K aligned, specifying that fpstate is 8-byte aligned achieves the same effect without needing to resort to hand coded alignments. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-03-10[ARM] 3356/1: Workaround for the ARM1136 I-cache invalidation problemCatalin Marinas
Patch from Catalin Marinas ARM1136 erratum 371025 (category 2) specifies that, under rare conditions, an invalidate I-cache by MVA (line or range) operation can fail to invalidate a cache line. The recommended workaround is to either invalidate the entire I-cache or invalidate the range by set/way rather than MVA. Note that for a 16K cache size, invalidating a 4K page by set/way is equivalent to invalidating the entire I-cache.

2006-03-07[ARM] 3352/1: DSB required for the completion of a TLB maintenance operationCatalin Marinas
Patch from Catalin Marinas Chapter B2.7.3 in the latest ARM ARM (with v6 information) states that the completion of a TLB maintenance operation is only guaranteed by the execution of a DSB (Data Syncronization Barrier, formerly Data Write Barrier or Drain Write Buffer). Note that a DSB is only needed in the flush_tlb_kernel_* functions since the completion is guaranteed by a mode change (i.e. switching back to user mode) for the flush_tlb_user_* functions.

2006-03-06[PATCH] fix next_timer_interrupt() for hrtimerTony Lindgren
Also from Thomas Gleixner <tglx@linutronix.de> Function next_timer_interrupt() got broken with a recent patch 6ba1b91213e81aa92b5cf7539f7d2a94ff54947c as sys_nanosleep() was moved to hrtimer. This broke things as next_timer_interrupt() did not check hrtimer tree for next event. Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ, VST) implementations, as the system can be in idle when next hrtimer event was supposed to happen. At least ARM and S390 currently use next_timer_interrupt().

2006-02-24[ARM] 3348/1: Disable GPIO interruptsAndrew Victor
Patch from Andrew Victor disable_irq() lazily disables the interrupt, so the IRQ is only disabled once the interrupt occurs again. The GPIO interrupt handler therefore must first check disable_depth to see if the IRQ needs to be disabled. Orignal patch by Bill Gatliff.

2006-02-22[ARM] 3347/1: Bugfix for ixp4xx_set_irq_type()Mårten Wikström
Patch from Mårten Wikström This patch fixes a bug in ixp4xx_set_irq_type() which leads to GPIO being incorrectly set to both edge triggered for raising as well as falling edge interrupt types.

2006-02-22[ARM] 3325/2: GPIO function to control multi-drive (open collector) capabilityAndrew Victor
Patch from Andrew Victor This patch adds the at91_set_multi_drive() function to enable/disable the multi-drive (open collector) pin capability on the AT91RM9200 processor. This is necessary to fix the UDC (USB Gadget) driver for the AT91RM9200 board as it will not allow the board reset line to be pulled low if the pullup is not driven as an open collector output as the boards are wired to the USB connector on both the DK/EK. This version of the patch updates it to 2.6.16-rc4. Orignal patch by Jeff Warren. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Patch from Uli Luckas This is a bugfix. The comment in arch/arm/common/rtctime.c explains it: * FIXME: for now, we just copy the alarm time because we're lazy (and * is therefore buggy - setting a 10am alarm at 8pm will not result in * the alarm triggering.) This patch adds one day to the alarm iff the alarm wrapped beyond midnight and therefore appears to be in the past.

2006-02-22[ARM] 3340/1: Fix the PCI setup for direct master access to SDRAMCatalin Marinas
Patch from Catalin Marinas The initial code did not configure the inbound memory windows for direct master access to the SDRAM. This patch creates a 1:1 mapping between the Versatile/PB PCI memory windows and its SDRAM. Note that an updated FPGA image is needed for Versatile/PB since the original windows were 1MB and not able to cover the whole SDRAM (now extended to 256MB). The patch also fixes the PCI IRQ mapping for slot #2. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

negative Patch from Nicolas Pitre The pre ARMv5 implementation can be aborted if an exception occurs in the middle of it.

2006-02-08[ARM] 3309/1: disable the pre-ARMv5 NPTL kernel helper in the non MMU caseNicolas Pitre
Patch from Nicolas Pitre The cmpxchg emulation on pre-ARMv5 relies on user code executed from a kernel address. If the operation cannot complete atomically, it is aborted from the usr_entry macro by clearing the Z flag. This clearing of the Z flag is done whenever the user pc is above TASK_SIZE. However this "pc >= TASK_SIZE" test cannot work in the non MMU case. Worse: the current code will corrupt the Z flag on every entry to the kernel. Let's disable it in the non MMU case for now. Using NPTL on non MMU targets needs to be worked out anyway. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
