2012-02-09ARM: LPC32xx: clock.c: Clock registration fixesRoland Stigge
This patch adjusts the clock registration list, ported from the latest version of Kevin Wells' latest version of clock.c: i2s0_ck, i2s1_ck and dev:mmc0 have NULL pointers associated as the .dev_id and .con_id, respectively. The old values were not useful. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Kevin Wells <kevin.wells@nxp.com> Signed-off-by: Olof Johansson <olof@lixom.net>
2012-02-09ARM: LPC32xx: clock.c: jiffies wrappingRoland Stigge
This patch fixes the jiffies wrapping bug in clock.c. It corrects the timeout computation based on jiffies, uses time_before() for correct wrapping handling and replaces a binary "&" which should really be a logical "&&" in a truth expression.

2012-02-09ARM: LPC32xx: clock.c: Fix mutex lock issuesRoland Stigge
This patch fixes the mutex issue in clock.c, as done in Kevin Wells' original driver update: In some cases, the clock drivers could grab a mutex twice in an improper context. This patch changes the mutex mechanism to a simple irq lock/unlock mechanism and removes un-needed locks from some functions.

Since commit 576d2f2525612ecb5af029a76f21f22a3b82563d "ARM: add generic ioremap optimization by reusing static mappings" ioremap() is trying to reuse existing static mapping when possible. The condition checking boundaries of the requested and existing mappings didn't take in-page offset into consideration though, which lead to obscure and hard to debug problems when requested mapping crossed end of the static one.

2012-01-25ARM: 7299/1: ftrace: clear zero bit in reported IPs for Thumb-2Rabin Vincent
The dynamic ftrace ops startup test currently fails on Thumb-2 kernels: Testing tracer function: PASSED Testing dynamic ftrace: PASSED Testing dynamic ftrace ops #1: (0 0 0 0 0) FAILED! This is because while the addresses in the mcount records do not have the zero bit set, the IP reported by the mcount call does have it set (because it is copied from the LR). This mismatch causes the ops filtering in ftrace_ops_list_func() to not call the relevant tracers. Fix this by clearing the zero bit before adjusting the LR for the mcount instruction size. Also, combine the mov+sub into a single sub instruction.

2012-01-25ARM: 7298/1: realview: fix mapping of MPCore private memory regionMarc Zyngier
Since commit 0536bdf33faf (ARM: move iotable mappings within the vmalloc region), the RealView PB11MP cannot boot anymore. This is caused by the way the mappings are described on this platform (define replaced by hex values for clarity): { /* GIC CPU interface mapping */ .virtual = IO_ADDRESS(0x1F000100), .pfn = __phys_to_pfn(0x1F000100), .length = SZ_4K, .type = MT_DEVICE, }, { /* GIC distributor mapping */ .virtual = IO_ADDRESS(0x1F001000), .pfn = __phys_to_pfn(0x1F001000), .length = SZ_4K, .type = MT_DEVICE, } The first mapping ends up reserving two pages, and clashes with the second one, which triggers a BUG_ON in vm_area_add_early(). In order to solve this problem, treat the MPCore private memory region (containing the SCU, the GIC and the TWD) as a single region, as described in the TRM: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html The EB11MP is converted the same way, even if it manages to avoid the problem.

2012-01-23ARM: 7297/1: smp_twd: make sure timer is stopped before registering itMarc Zyngier
On secondary CPUs, the Timer Control Register is not reset to a sane value before the timer is registered, and the TRM doesn't seem to indicate any reset value either. In some cases, the kernel will take an interrupt too early, depending on what junk was present in the registers at reset time. The fix is to set the Timer Control Register to 0 before registering the clock_event_device and enabling the interrupt. Problem seen on VE (Cortex A5) and Tegra.

2012-01-23ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMPWill Deacon
It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

2012-01-23ARM: 7291/1: cache: assume 64-byte L1 cachelines for ARMv7 CPUsWill Deacon
To ensure correct alignment of cacheline-aligned data, the maximum cacheline size needs to be known at compile time. Since Cortex-A8 and Cortex-A15 have 64-byte cachelines (and it is likely that there will be future ARMv7 implementations with the same line size) then it makes sense to assume that CPU_V7 implies a 64-byte L1 cacheline size. For CPUs with smaller caches, this will result in some harmless padding but will help with single zImage work and avoid hitting subtle bugs with misaligned data structures.

2012-01-23ARM: 7290/1: vmlinux.lds.S: align the exception fixup table to a 4-byte boundaryWill Deacon
The exception fixup table is currently aligned to a 32-byte boundary. Whilst this won't cause any problems, the exception_table_entry structures contain only a pair of unsigned longs, so 4-byte alignment is all that is required. If the table was walked from start to end, cacheline alignment may bring some performance benefits, but since a binary search is used, the access pattern is random and will not benefit from a stricter alignment.

2012-01-20Revert "ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp ↵Russell King
bus." This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register.

With commit 5def51b (ARM: 7211/1: smp_twd: get the rate from a clock) hitting mainline, if we do not have a twd_clk for lookup, we will see the following error message in boot log. smp_twd: clock not found: -2 Actually we should add this clock regardless of the error message, so that we can: * Avoid the local timer calibrating at boot time * Make the local timer cpufreq aware on imx6q Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2012-01-19ARM: 7277/1: setup.c: Fix build warning by removing unneeded header fileFabio Estevam
Fix the following build warning: CC arch/arm/kernel/setup.o In file included from arch/arm/kernel/setup.c:39: arch/arm/include/asm/elf.h:102:1: warning: "vmcore_elf64_check_arch" redefined In file included from arch/arm/kernel/setup.c:24: include/linux/crash_dump.h:30:1: warning: this is the location of the previous definition Since commit 93a72052 (crash_dump: export is_kdump_kernel to modules, consolidate elfcorehdr_addr, setup_elfcorehdr and saved_max_pfn) the inclusion of <linux/crash_dump.h> is no longer needed. Remove the inclusion of <linux/crash_dump.h> and the build warning is fixed. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-01-19ARM: 7279/1: standardize /proc/iomem "Kernel code" nameKees Cook
All other ports use "Kernel code" to identify the Kernel text segment in /proc/iomem. Change the ARM resources to do the same. Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-01-19ARM: fix rcu stalls on SMP platformsRussell King
We can stall RCU processing on SMP platforms if a CPU sits in its idle loop for a long time. This happens because we don't call irq_enter() and irq_exit() around generic_smp_call_function_interrupt() and friends. Add the necessary calls, and remove the one from within ipi_timer(), so that they're all in a common place. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

f408c985cefc (GPIO: sa1100: implement proper gpiolib gpio_to_irq conversion) made gpio_to_irq() a function. This breaks collie where it's used to initialize some static data.
