2016-03-29perf tools: Add missing initialization of perf_sample.cpumode in synthesized ↵Arnaldo Carvalho de Melo
samples In 473398a21d28 ("perf tools: Add cpumode to struct perf_sample"), I missed some places where perf_sample fields are directly initialized in addition to what is done in perf_evsel__parse_sample(), namely when synthesizing PERF_RECORD_{MMAP*,COMM,FORK,EXIT} for pre-existing threads and also in intel_pt and intel_bts when synthesizing events from processor trace, the jitdump code also was affected, fix it. The problem was noticed with running: # perf record -e intel_pt//u true # perf script Where the samples wouldn't get resolved because perf_sample.cpumode would be left as zero, i.e. PERF_RECORD_MISC_CPUMODE_UNKNOWN, not resolving as kernel, hypervisor or user cpu modes.

2016-03-29MIPS: cpu_name_string: Use raw_smp_processor_id().James Hogan

These two functions are used by various exception handling functions, only some of which ensure that interrupts or preemption is disabled. However the following have interrupts explicitly enabled or not explicitly disabled: - do_reserved() (irqs enabled) - do_ade() (irqs not disabled) This can be hit by setting /sys/kernel/debug/mips/unaligned_action to 2, and triggering an address error exception, e.g. an unaligned access or access to kernel segment from user mode. To fix the above cases, use raw_smp_processor_id() instead. It is unusual for CPU names to be different in the same system, and even if they were, its possible the process has migrated between the exception of interest and the cpu_name_string() call anyway.

remove the usage of removed irq_to_gpio() function. On pre-DB1200 boards, pass the actual carddetect GPIO number instead of the IRQ, because we need the gpio to actually test card status (inserted or not) and can get the irq number with gpio_to_irq() instead.

2016-03-29staging: lustre: libcfs: replace direct HZ access with kernel APIsJian Yu
On some customers' systems, the kernel was compiled with HZ defined to 100, instead of 1000. This improves performance for HPC applications. However, to use these systems with Lustre, customers have to re-build Lustre for the kernel because Lustre directly uses the defined constant HZ. Since kernel 2.6.21, some non-HZ dependent timing APIs become non- inline functions, which can be used in Lustre codes to replace the direct HZ access. These kernel APIs include: jiffies_to_msecs() jiffies_to_usecs() jiffies_to_timespec() msecs_to_jiffies() usecs_to_jiffies() timespec_to_jiffies() And here are some samples of the replacement: HZ -> msecs_to_jiffies(MSEC_PER_SEC) n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC) HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n) n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC n / HZ * 1000 -> jiffies_to_msecs(n) This patch replaces the direct HZ access in the libcfs module.

2016-03-29staging: lustre: libcfs: bug fixes for cfs_crypto_hash_final()Andreas Dilger
Change cfs_crypto_hash_final() to always clean up the hash descrptor instead of not doing this in error cases. All of the callers were just calling cfs_crypto_hash_final() immediately to clean up the descriptor anyway, and the old behaviour is unlike other init/fini functions, and prone to memory leaks and other incorrect usage. The callers can call cfs_crypto_digest_size() to determine the hash size in advance if needed, and avoid complexity in cfs_crypto_hash_final().
