| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Émeric Maschino <emeric.maschino@gmail.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * | cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystemKay Sievers2011-12-21
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the 'cpu sysdev_class' over to a regular 'cpu' subsystem and converts the devices to regular devices. The sysdev drivers are implemented as subsystem interfaces now. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are made available with this conversion.

* / [IA64] Merge overlapping reserved regions at bootPetr Tesarik2011-12-09
|/ | | | | | | | | | | | | | | | | | | | | | While working on the upcoming SLES11 SP2, I ran into an issue with booting the panic kernel on a kernel crash. In the first iteration I found out that the initial register backing store gets overwritten with zeroes, causing a kernel crash shortly afterwards. Further investigation revealed that rsvd_region[] contains overlapping entries: find_memmap_space() returns a pointer which lies between KERNEL_START and _end. This is correct with the EFI memmap as patched by the kexec purgatory code. That code removes vmlinux LOAD segments from the usable map, but there is a pretty large hole between the gate section and the per-cpu section. This happens because reserve_memory() blindly marks [KERNEL_START, __end] as reserved, even though there is a free block in the middle in the kexec case because it noticed a large gap between sections and modified the efi_memory_map to account for this.

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.

In order to do so we need a generic callback from the existing scheduler IPI. This patch introduces such a generic callback: scheduler_ipi() and implements it as a NOP. BenH notes: PowerPC might use this IPI on offline CPUs under rare conditions!

* / / [CPUFREQ] use dynamic debug instead of custom infrastructureDominik Brodowski2011-05-04
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
