[PATCH] AGP fix for Xen VMM

2005-06-07T19:35:43Z

When Linux is running on the Xen virtual machine monitor, physical addresses are virtualised and cannot be directly referenced by the AGP GART. This patch fixes the GART driver for Xen by adding a layer of abstraction between physical addresses and 'GART addresses'. Architecture-specific functions are also defined for allocating and freeing the GATT. Xen requires this to ensure that table really is contiguous from the point of view of the GART. These extra interface functions are defined as 'no-ops' for all existing architectures that use the GART driver. Signed-off-by: Keir Fraser Signed-off-by: Andrew Morton Signed-off-by: Dave Jones

[PATCH] ppc32: add to

2005-06-07T00:02:02Z

On ppc32, uses __user, but doesn't directly include . This adds that in. Without this, glibc will not compile. Signed-off-by: Tom Rini Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ppc32: Support for 82xx PQII on-chip PCI bridge

2005-05-28T23:46:15Z

This patch adds on-chip PCI bridge support for the PQ2 family. The incomplete existent code is updated with interrupt handling stuff and board-specific bits for 8272ADS and PQ2FADS; the related files were renamed (from m8260_pci to m82xx_pci) to be of more generic fashion. This is tested with 8266ADS and 8272ADS, should work on PQ2FADS as well. Signed-off-by: Vitaly Bordug Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] asm/signal.h unification

2005-05-04T14:33:15Z

New file - asm-generic/signal.h. Contains declarations of __sighandler_t, __sigrestore_t, SIG_DFL, SIG_IGN, SIG_ERR and default definitions of SIG_BLOCK, SIG_UNBLOCK and SIG_SETMASK. asm-*/signal.h switched to including it. The only exception is asm-parisc/signal.h that wants its own declaration of __sighandler_t; that one is left as-is. asm-ppc64/signal.h required one more thing - unlike everybody else it used __sigrestorer_t instead of usual __sigrestore_t. PPC64 switched to common spelling. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds

[PATCH] ppc32: Fix might_sleep() warning with clock spreading

2005-05-02T15:15:22Z

The clock spreading disable/enable code was called to late/early during the suspend/resume code on some laptops and would trigger a might_sleep() warning due to the down() call in the low level i2c code. This fixes it by calling those functions earlier/later when interrupts are still enabled. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Linus Torvalds

[PATCH] move SA_xxx defines to linux/signal.h

2005-05-01T15:59:02Z

The attached patch moves the IRQ-related SA_xxx flags (namely, SA_PROBE, SA_SAMPLE_RANDOM and SA_SHIRQ) from all the arch-specific headers to linux/signal.h. This looks like a left-over after the irq-handling code was consolidated. The code was moved to kernel/irq/*, but the flags are still left per-arch. Right now, adding a new IRQ flag to the arch-specific header, like this patch does: http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1 no longer works, it breaks the compilation for all other arches, unless you add that flag to all the other arch-specific headers too. So I think such a clean-up makes sense. Signed-off-by: Stas Sergeev Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] remove all kernel BUGs

2005-05-01T15:59:01Z

This patch eliminates all kernel BUGs, trims about 35k off the typical kernel, and makes the system slightly faster. Signed-off-by: Matt Mackall Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ppc32: refactor FPU exception handling

2005-05-01T15:58:40Z

Moved common FPU exception handling code out of head.S so it can be used by several of the sub-architectures that might of a full PowerPC FPU. Also, uses new CONFIG_PPC_FPU define to fix alignment exception handling for floating point load/store instructions to only occur if we have a hardware FPU.

[PATCH] ppc iomem annotations: ->io_base_virt

2005-04-25T14:55:57Z

* ->io_base_virt in struct pci_controller is iomem pointer. Marked as such. Most of the places that used it are already annotated to expect iomem. * places that did gratitious (and wrong) casts a-la isa_io_base = (unsigned long)ioremap(...); hose->io_base_virt = (void *)isa_io_base; turned into hose->io_base_virt = ioremap(...); isa_io_base = (unsigned long)hose->io_base_virt; * pci_bus_io_base() annotated as returning iomem pointer.
