| * ia64: Add accept4() syscallÉmeric Maschino2012-05-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 65cc21b4523e94d5640542a818748cd3be8cd6b4 upstream. While debugging udev > 170 failure on Debian Wheezy (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=648325), it appears that the issue was in fact due to missing accept4() in ia64. This patch simply adds accept4() to ia64.

| * ACPI, ia64: Use SRAT table rev to use 8bit or 16/32bit PXM fields (ia64)Kurt Garloff2012-01-251-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 9f10f6a520deb3639fac78d81151a3ade88b4e7f upstream. In SRAT v1, we had 8bit proximity domain (PXM) fields; SRAT v2 provides 32bits for these. The new fields were reserved before. According to the ACPI spec, the OS must disregrard reserved fields. ia64 did handle the PXM fields almost consistently, but depending on sgi's sn2 platform. This patch leaves the sn2 logic in, but does also use 16/32 bits for PXM if the SRAT has rev 2 or higher. The patch also adds __init to the two pxm accessor functions, as they access __initdata now and are called from an __init function only anyway. Note that the code only uses 16 bits for the PXM field in the processor proximity field; the patch does not address this as 16 bits are more than enough.

The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W.

* | | [CPUFREQ] use dynamic debug instead of custom infrastructureDominik Brodowski2011-05-041-23/+21
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With dynamic debug having gained the capability to report debug messages also during the boot process, it offers a far superior interface for debug messages than the custom cpufreq infrastructure. As a first step, remove the old cpufreq_debug_printk() function and replace it with a call to the generic pr_debug() function. How can dynamic debug be used on cpufreq? You need a kernel which has CONFIG_DYNAMIC_DEBUG enabled. To enabled debugging during runtime, mount debugfs and $ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control for debugging the complete "cpufreq" module. To achieve the same goal during boot, append ddebug_query="module cpufreq +p" as a boot parameter to the kernel of your choice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ia64_mca_cpu_init has a void *data local variable that is assigned the value from either __get_free_pages() or mca_bootmem(). The problem is that __get_free_pages returns an unsigned long and mca_bootmem, via alloc_bootmem(), returns a void *. format_mca_init_stack takes the void *, and it's also used with __pa(), but that casts it to long anyway. This results in the following build warning: arch/ia64/kernel/mca.c:1898: warning: assignment makes pointer from integer without a cast Cast the return of __get_free_pages to a void * to avoid the warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SAL requires that interrupts be enabled when making some calls to it to pick up error records, so we enable interrupts inside this handler. We should disable them again at the end. Found by a new WARN_ONCE that tglx added to handle_irq_event_percpu() Signed-off-by: Tony Luck <tony.luck@intel.com>

| * | | percpu: align percpu readmostly subsection to cachelineTejun Heo2011-01-251-1/+1
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently percpu readmostly subsection may share cachelines with other percpu subsections which may result in unnecessary cacheline bounce and performance degradation. This patch adds @cacheline parameter to PERCPU() and PERCPU_VADDR() linker macros, makes each arch linker scripts specify its cacheline size and use it to align percpu subsections. This is based on Shaohua's x86 only patch. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Shaohua Li <shaohua.li@intel.com>
