2009-04-23[S390] omit frame pointers on s390 when possibleHeiko Carstens
Always omit frame pointers on s390. They aren't too useful for the kernel since we have already the kernel stack backchain which allows us to walk the kernel stack. So eleminate the extra code for frame pointers. Only allow the extra code for the function tracer since the gcc compile options -pg and -fomit-frame-pointer are incompatible.

2009-04-23[S390] /proc/stat idle field for idle cpusMartin Schwidefsky
The cpu idle field in the output of /proc/stat is too small for cpus that have been idle for more than a tick. Add the architecture hook arch_idle_time that allows to add the not accounted idle time of a sleeping cpu without waking the cpu. The s390 implementation of arch_idle_time uses the already existing s390_idle_data per_cpu variable to find the sleep time of a neighboring idle cpu.

2009-04-23[S390] appldata: avoid deadlock with appldata_memGerald Schaefer

2009-04-23GFS2: Ensure that the inode goal block settings are updatedSteven Whitehouse
GFS2 has a goal block associated with each inode indicating the search start position for future block allocations (in fact there are two, but thats for backward compatibility with GFS1 as they are set to identical locations in GFS2). In some circumstances, depending on the ordering of updates to the inode it was possible for the goal block settings to not be updated on disk. This patch ensures that the goal block will always get updated, thus reducing the potential for searching the same (already allocated) blocks again when looking for free space during block allocation.

The current ad1884a-mobile model has a problem that the speaker output doesn't work sometimes after boot or power-saving on some HP laptops. It seems that the verbs accessing to the non-functional widgets cause this problem. This patch simplifies the init verbs for mobile model not to touch unnecessary setups so that it avoids the speaker-mute problem.

2009-04-22ACPI: delete obsolete "bus master activity" proc fieldLen Brown

This patch could break programs that parse /proc/acpi/processor/*/power, since it deletes this line from that file: bus master activity: 00000000 http://bugzilla.kernel.org/show_bug.cgi?id=13145 is not fixed by this patch, but provoked this patch.

The c2 and c3 idle handlers check tsc_halts_in_c() after every time they return from idle.

2009-04-22PCI: only save/restore existent registers in the PCIe capabilityYu Zhao
PCIe 1.1 base neither requires the endpoint to implement the entire PCIe capability structure nor specifies default values of registers that are not implemented by the device. So we only save and restore registers that must be implemented by different device types if the device PCIe capability version is 1. PCIe 1.1 Capability Structure Expansion ECN and PCIe 2.0 requires all registers in the PCIe capability to be either implemented or hardwired to 0. Their PCIe capability version is 2.

2009-04-22eCryptfs: Larger buffer for encrypted symlink targetsTyler Hicks
When using filename encryption with eCryptfs, the value of the symlink in the lower filesystem is encrypted and stored as a Tag 70 packet. This results in a longer symlink target than if the target value wasn't encrypted. Users were reporting these messages in their syslog: [ 45.653441] ecryptfs_parse_tag_70_packet: max_packet_size is [56]; real packet size is [51] [ 45.653444] ecryptfs_decode_and_decrypt_filename: Could not parse tag 70 packet from filename; copying through filename as-is This was due to bufsiz, one the arguments in readlink(), being used to when allocating the buffer passed to the lower inode's readlink(). That symlink target may be very large, but when decoded and decrypted, could end up being smaller than bufsize. To fix this, the buffer passed to the lower inode's readlink() will always be PATH_MAX in size when filename encryption is enabled. Any necessary truncation occurs after the decoding and decrypting.
