2008-05-03unified (weak) sys_pipe implementationUlrich Drepper1-13/+0
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

Use the generic pci_enable_resources() instead of the arch-specific code. Unlike this arch-specific code, the generic version: - checks PCI_NUM_RESOURCES (11), not DEVICE_COUNT_RESOURCE (12), resources - skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set - skips ROM resources unless IORESOURCE_ROM_ENABLE is set - checks for resource collisions with "!r->parent" Signed-off-by: Bjorn Helgaas <[email protected]> Acked-by: Kyle McMartin <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

None of these files use any of the functionality promised by asm/semaphore.h. It's possible that they rely on it dragging in some unrelated header file, but I can't build all these files, so we'll have fix any build failures as they come up. Signed-off-by: Matthew Wilcox <[email protected]>

2008-03-15[PARISC] pdc_console: fix bizarre panic on bootKyle McMartin2-12/+34
Commit 721fdf34167580ff98263c74cead8871d76936e6 introduced a subtle bug by accidently removing the "static" from iodc_dbuf. This resulted in, what appeared to be, a trap without *current set to a task. Probably the result of a trap in real mode while calling firmware. Also do other misc clean ups. Since the only input from firmware is non blocking, share iodc_dbuf between input and output, and spinlock the only callers. Signed-off-by: Kyle McMartin <[email protected]>

2007-12-06[PARISC] timer interrupt should not be IRQ_DISABLEDKyle McMartin1-1/+1
The timer interrupt had accidentally been marked IRQ_DISABLED since IRQ_PER_CPU had been OR-ed in, instead of set. This had been working by accident for quite a while. Commit c642b8391cf8efc3622cc97329a0f46e7cbb70b8 changed the behaviour of IRQ_PER_CPU interrupts, which previously weren't checked for IRQ_DISABLED. Signed-off-by: Kyle McMartin <[email protected]>

One of the easiest things to isolate is the pid printed in kernel log. There was a patch, that made this for arch-independent code, this one makes so for arch/xxx files.

2007-10-19pid namespaces: changes to show virtual ids to userPavel Emelyanov1-1/+1
This is the largest patch in the set. Make all (I hope) the places where the pid is shown to or get from user operate on the virtual pids. The idea is: - all in-kernel data structures must store either struct pid itself or the pid's global nr, obtained with pid_nr() call; - when seeking the task from kernel code with the stored id one should use find_task_by_pid() call that works with global pids; - when showing pid's numerical value to the user the virtual one should be used, but however when one shows task's pid outside this task's namespace the global one is to be used; - when getting the pid from userspace one need to consider this as the virtual one and use appropriate task/pid-searching functions.
