* get_unmapped_area handles MAP_FIXED on pariscBenjamin Herrenschmidt2007-05-07
| | | | | | | | | | | | | | Handle MAP_FIXED in parisc arch_get_unmapped_area(), just return the address. We might want to also check for possible cache aliasing issues now that we get called in that case (like ARM or MIPS), leave a comment for the maintainers to pick up.

* [PATCH] x86: Allow percpu variables to be page-alignedJeremy Fitzhardinge2007-05-02
| | | | | | | | | | | | | | | Let's allow page-alignment in general for per-cpu data (wanted by Xen, and Ingo suggested KVM as well). Because larger alignments can use more room, we increase the max per-cpu memory to 64k rather than 32k: it's getting a little tight.

* libata/IDE: remove combined mode quirkJeff Garzik2007-04-28
| | | | | | | | | | | | | | | | | | | | | Both old-IDE and libata should be able handle all controllers and devices found using normal resource reservation methods. This eliminates the awful, low-performing split-driver configuration where old-IDE drove the PATA portion of a PCI device, in PIO-only mode, and libata drove the SATA portion of the /same/ PCI device, in DMA mode. Typically vendors would ship SATA hard drive / PATA optical configuration, which would lend itself to slow (PIO-only) CD-ROM performance. For Intel users running in combined mode, it is now wholly dependent on your driver choice (potentially link order, if you compile both drivers in) whether old-IDE or libata will drive your hardware. In either case, you will get full performance from both SATA and PATA ports now, without having to pass a kernel command line parameter. Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PARISC] clocksource: Move update_cr16_clocksource later in bootKyle McMartin2007-02-26
| | | | | | | | | | | smp_cpus_done is too early for us... before we even do a device inventory! Move update_cr16_clocksource into the tail end of processor_probe() and stub it out on CONFIG_SMP=n builds. Verified that clocksource0 is properly updated to use jiffies on an SMP build.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In copy_siginfo_from_user32: Use compat_uptr_t. Use compat_ptr(). In copy_siginfo_to_user32: Use compat_int_t. Use ptr_to_compat(). The sigevent_t structure has a 64-bit si_ptr field that when copied to a 32-bit si_ptr will copy the wrong word. For the compat copy use the si_int field instead.

| * [PARISC] Fix show_stack() when we can't kmallocMatthew Wilcox2007-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | show_stack() was calling kzalloc() to allocate a struct pt_regs. This meant that *really* early stack dumps would cause a null pointer dereference. x86_64 allocates its pt_regs on the stack, so do the same. Kyle actually committed this exact patch to CVS on Wed Jul 26 14:32:39 2006 UTC, and never moved it across to git. Bad Kyle.
