* unified (weak) sys_pipe implementationUlrich Drepper2008-05-031-13/+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 <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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 <bjorn.helgaas@hp.com> Acked-by: Kyle McMartin <kyle@mcmartin.ca> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility.

* [PARISC] pdc_console: fix bizarre panic on bootKyle McMartin2008-03-162-12/+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 <kyle@parisc-linux.org>
* [PARISC] dump_stack in show_regsKyle McMartin2008-03-161-0/+2
| | | | | | | | Originally, show_stack was used in BUG() output. However, a recent commit changed it to print register state (no idea what that's supposed to help, really...) and parisc was missing a backtrace because of it. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

* [PARISC] timer interrupt should not be IRQ_DISABLEDKyle McMartin2007-12-061-1/+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.
