2009-03-24ide: fix ->init_chipset method to return 'int' valueBartlomiej Zolnierkiewicz
* Return 0 instead of dev->irq in ->init_chipset implementations. * Fix ->init_chipset method to return 'int' value instead of 'unsigned int' one. This fixes ->init_chipset handling for host drivers (cs5530, hpt366 and pdc202xx_new) for which it is possible for this method to fail. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2009-03-23Linux 2.6.29Linus Torvalds
2009-03-23Build with -fno-dwarf2-cfi-asmKyle McMartin
With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections. (This was reported against Fedora, which appears to be the only distro doing any building against gcc-4.4 at present: RH bz#486545.)

2009-03-23fix ptrace slownessMiklos Szeredi
This patch fixes bug #12208: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208 Subject : uml is very slow on 2.6.28 host This turned out to be not a scheduler regression, but an already existing problem in ptrace being triggered by subtle scheduler changes. The problem is this: - task A is ptracing task B - task B stops on a trace event - task A is woken up and preempts task B - task A calls ptrace on task B, which does ptrace_check_attach() - this calls wait_task_inactive(), which sees that task B is still on the runq - task A goes to sleep for a jiffy - ... Since UML does lots of the above sequences, those jiffies quickly add up to make it slow as hell. This patch solves this by not rescheduling in read_unlock() after ptrace_stop() has woken up the tracer. Thanks to Oleg Nesterov and Ingo Molnar for the feedback.
