Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it to lib/Kconfig.debug so each arch doesn't have to define it. This obviously makes the option generic, but that's fine because the config is already used in generic code. It's not obvious to me that sysrq-P actually does anything caution by keeping the most inclusive wording. Signed-off-by:

DEBUG_PER_CPU_MAPS is used in lib/cpumask.c as well as in inlcude/linux/cpumask.h and thus it has outgrown its use within x86 and powerpc alone. Any arch with SMP support may want to get some more debugging, so make this option generic. Signed-off-by:

There is quite a lot of code which does copy_from_user() + strict_strto*() or simple_strto*() combo in slightly different ways. Before doing conversions all over tree, let's get final API correct. Enter kstrtoull_from_user() and friends. Typical code which uses them looks very simple: TYPE val; int rv; rv = kstrtoTYPE_from_user(buf, count, 0, &val); if (rv < 0) return rv; [use val] return count; There is a tiny semantic difference from the plain kstrto*() API -- the latter allows any amount of leading zeroes, while the former copies data into buffer on stack and thus allows leading zeroes as long as it fits into buffer. This shouldn't be a problem for typical usecase "echo 42 > /proc/x". The point is to make reading one integer from userspace _very_ simple and very bug free. Signed-off-by:

This function makes a deep copy of the platform data to allow it to live in init memory. For a kernel that supports several machines and so includes the definition for several leds-gpio devices this saves quite some memory because all but one definition can be free'd after boot. As the function is used by arch code it must be builtin and so cannot go into leds-gpio.c. [akpm@linux-foundation.org: s/CONFIG_LED_REGISTER_GPIO/CONFIG_LEDS_REGISTER_GPIO/] Signed-off-by:

Allow unused leds on pca9532 to be used as gpio. The board I am working on now has no less than 6 pca9532 chips. One chips is used for only leds, one has 14 leds and 2 gpio and the rest of the chips are gpio only. There is also one board in mainline which could use this capabilty; arch/arm/mach-iop32x/n2100.c 232 { .type = PCA9532_TYPE_NONE }, /* power OFF gpio */ 233 { .type = PCA9532_TYPE_NONE }, /* reset gpio */ This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a gpiochip if any pin has this type set. The gpio will registers all chip pins but will filter on gpio_request. [randy.dunlap@oracle.com: fix build when GPIOLIB is not enabled] Signed-off-by:Wolfram Sang <w.sang@pengutronix.de> Reviewed-by:

By setting initial values blink_delay_on and blink_delay_off in a led_classdev struct, this change starts the blinking when the led is initialized. With this patch, you can initialize blink_delay_on and blink_delay_off in led_classdev with default_trigger set to "timer", and the led will start up blinking. The current ledtrig-timer implementation ignores any initial blink_delay_on/blink_delay_off settings, and requires setting blink_delay_on/blink_delay_off (typically from userspace) before the led blinks.

On larger systems, because of the numerous ACPI, Bootmem and EFI messages, the static log buffer overflows before the larger one specified by the log_buf_len param is allocated. Minimize the overflow by allocating the new log buffer as soon as possible. On kernels without memblock, a later call to setup_log_buf from kernel/init.c is the fallback.

On larger systems, information in the kernel log is lost because there is so much early text printed, that it overflows the static log buffer before the log_buf_len kernel parameter can be processed, and a bigger log buffer allocated. Distros are relunctant to increase memory usage by increasing the size of the static log buffer, so minimize the problem by allocating the new log buffer as early as possible.

A fix to the TSC (Time Stamp Counter) based bogoMIPS calculation used on secondary CPUs which has two faults: 1: Not handling wrapping of the lower 32 bits of the TSC counter on 32bit kernel - perhaps TSC is not reset by a warm reset? 2: TSC and Jiffies are no incrementing together properly. Either jiffies increment too quickly or Time Stamp Counter isn't incremented in during an SMI but the real time clock is and jiffies are incremented. Case 1 can result in a factor of 16 too large a value which makes udelay() values too small and can cause mysterious driver errors. Case 2 appears to give smaller 10-15% errors after averaging but enough to cause occasional failures on my own board I have tested this code on my own branch and attach patch suitable for current kernel code. See below for examples of the failures and how the fix handles these situations now. I reported this issue earlier here: Intermittent problem with BogoMIPs calculation on Intel AP CPUs - http://marc.info/?l=linux-kernel&m=129947246316875&w=4 I suspect this issue has been seen by others but as it is intermittent and bogoMIPS for secondary CPUs are no longer printed out it might have been difficult to identify this as the cause. Perhaps these unresolved issues, although quite old, might be relevant as possibly this fault has been around for a while. In particular Case 1 may only be relevant to 32bit kernels on newer HW (most people run 64bit kernels?). Case 2 is less dramatic since the earlier fix in this area and also intermittent. Re: bogomips discrepancy on Intel Core2 Quad CPU - http://marc.info/?l=linux-kernel&m=118929277524298&w=4 slow system and bogus bogomips - http://marc.info/?l=linux-kernel&m=116791286716107&w=4 Re: Re: [RFC-PATCH] clocksource: update lpj if clocksource has - http://marc.info/?l=linux-kernel&m=128952775819467&w=4 This issue is masked a little by commit feae3203 ("timers, init: Limit the number of per cpu calibration bootup messages") which only prints out the first bogoMIPS value making it much harder to notice other values differing. Perhaps it should be changed to only suppress them when they are similar values? Here are some outputs showing faults occurring and the new code handling them properly.

af4f1360 ("security: move LSM xattrnames to xattr.h") moved the XATTR_CAPS_SUFFIX define from capability.h to xattr.h. This makes sense except it was previously exports to userspace but xattr.h does not export it to userspace. This patch exports these headers to userspace to fix the ABI regression. There is some slight possibility that this will cause problems in other applications which used these #defines differently (wrongly) and I could JUST export the capabilities xattr name that we broke. Does anyonehave an idea how exposing these headers could cause a problem? Below is what is being exposed to userspace, included here since it isn't clear exactly what is going to be made available from the patch. /* Namespaces */ #define XATTR_OS2_PREFIX "os2." #define XATTR_OS2_PREFIX_LEN (sizeof (XATTR_OS2_PREFIX) - 1) #define XATTR_SECURITY_PREFIX "security." #define XATTR_SECURITY_PREFIX_LEN (sizeof (XATTR_SECURITY_PREFIX) - 1) #define XATTR_SYSTEM_PREFIX "system." #define XATTR_SYSTEM_PREFIX_LEN (sizeof (XATTR_SYSTEM_PREFIX) - 1) #define XATTR_TRUSTED_PREFIX "trusted." #define XATTR_TRUSTED_PREFIX_LEN (sizeof (XATTR_TRUSTED_PREFIX) - 1) #define XATTR_USER_PREFIX "user." #define XATTR_USER_PREFIX_LEN (sizeof (XATTR_USER_PREFIX) - 1) /* Security namespace */ #define XATTR_SELINUX_SUFFIX "selinux" #define XATTR_NAME_SELINUX XATTR_SECURITY_PREFIX XATTR_SELINUX_SUFFIX #define XATTR_SMACK_SUFFIX "SMACK64" #define XATTR_SMACK_IPIN "SMACK64IPIN" #define XATTR_SMACK_IPOUT "SMACK64IPOUT" #define XATTR_NAME_SMACK XATTR_SECURITY_PREFIX XATTR_SMACK_SUFFIX #define XATTR_NAME_SMACKIPIN XATTR_SECURITY_PREFIX XATTR_SMACK_IPIN #define XATTR_NAME_SMACKIPOUT XATTR_SECURITY_PREFIX XATTR_SMACK_IPOUT #define XATTR_CAPS_SUFFIX "capability" #define XATTR_NAME_CAPS XATTR_SECURITY_PREFIX XATTR_CAPS_SUFFIX Reported-by:

Manually adjusting the smp_affinity for IRQ's becomes unwieldy when the cpu count is large. Setting smp affinity to cpus 256 to 263 would be: echo 000000ff,00000000,00000000,00000000,00000000,00000000,00000000,00000000 > smp_affinity instead of: echo 256-263 > smp_affinity_list Think about what it looks like for cpus around say, 4088 to 4095. We already have many alternate "list" interfaces: /sys/devices/system/cpu/cpuX/indexY/shared_cpu_list /sys/devices/system/cpu/cpuX/topology/thread_siblings_list /sys/devices/system/cpu/cpuX/topology/core_siblings_list /sys/devices/system/node/nodeX/cpulist /sys/devices/pci***/***/local_cpulist Add a companion interface, smp_affinity_list to use cpu lists instead of cpu maps. This conforms to other companion interfaces where both a map and a list interface exists. This required adding a bitmap_parselist_user() function in a manner similar to the bitmap_parse_user() function. [akpm@linux-foundation.org: make __bitmap_parselist() static] Signed-off-by:
