The default interruption handler "handle_interruption" does not properly check to see if the faulting space is the same as the users space. The problem lies in the fact that if a fault happens on the gateway we will not deliver signals to the process, the process will not die, and we may continue handling the same fault in a loop forever. Any malicious user code can crash the kernel by jumping into the gateway page at an inopportune address. The solution is to check if the user has the right privilege and if the spaces match, both faulting and currently active. The best action is to force the process back to it's own space of execution at address zero, and let it take a SIGSEGV. The process can never recover from this because it happens immediately after the return from the interrupt via rfi or rfir. Committed-by:Carlos O'Donell <carlos@parisc-linux.org>

- new memcpy routine, replaces memcpy, bcopy, copy_{from,to,in}_user implementations - workaround gcc-3.0 limitations for asm() - Pip and Rufus pointed out the flaw in the current misaligned memcopy routines. Randolph now owes lots of Milk bones. - updates to work with testsuite - sparse annotations - Improve copy performance for small and unaligned copies - Enable merge optimization for non-PA20 builds too Committed-by:James Bottomley <jejb@parisc-linux.org>

fix CONFIG_DISCONTIGMEM support Committed-by: -

- Fix Astro/Elroy LMMIO space reporting in /proc/iomem. - Output in /proc/iomem include PCI bus number and "Extra LMMIO" range. - LBA now reports proper addresses routed down from SBA. - add mercury_cfg_ops. This fixes the tg3 init delay problem. PDC took ~20ms per PCI cfg write. tg3 performs ~1600 writes (~30 seconds per NIC) during init. Alternative is the relocate PDC to host ram. But that would burn ~4MB of RAM. This is cheaper. - add PCI_F_EXTEND to asm/pci.h - replaces private definitions Committed-by: -

Patch from Ben Dooks Fixes mis-labelled timer variables, and incldes the clock header to allow the code to compile. This was not caught on previous rounds as all the s3c2440 machine support is pending the finalisation of the new s3c2440 uart driver (arriving soon) Signed-off-by: Ben Dooks

Patch from Ben Dooks Select the PCLK based TIMER4 to provide the system timer tick if there is no machine specific timer setup specified. This should make it easier to add new machines, as well as cut down on the code required in time.c when they are added. Signed-off-by: Ben Dooks

Patch from George G. Davis The Lubbock PCMCIA socket driver, drivers/pcmcia/pxa2xx_lubbock.c, lacks a MODULE_LICENSE declaration. This patch merely adds the missing MODULE_LICENSE declaration to eliminate tainted kernel warnings when this driver is built as a module. I have intentionally not used the Dual MPL/GPL license in this case because 1) current linux-2.6.10-rc1 PXA PCMCIA drivers use only the GPL license, 2) the original source files on which the PXA PCMCIA drivers are based, i.e. the SA11xx PCMCIA drivers, state: "If you wish to allow the use of your version of this file only under the terms of the GPL and not to allow others to use your version of this file under the MPL, indicate your decision by deleting the provisions above and replace them with the notice and other provisions required by the GPL."

Here's the patch that supercedes the one I asked you to drop. It changes the fan speed logic so that the fans will go incrementally fast instead of using just two steps. Also, it starts and stops both fans instead of just one on Powerbooks 15" and 17" (functionality asked by most of the Albooks users on Debian's ML, and justified by the fact that fan 1 and fan 2 do not correspond to CPU and GPU, as we previously thought).

This is a small patch to deviceiobook.tmpl to describe the new mmiowb routine a bit more completely. I've also updated it to provide pointers to drivers that do write flushing, use mmiowb, and use the readX_relaxed routines. Acked-by:

Cleanup/bugfix HPET driver: - hpet_init() could return failure with driver still registered with ACPI - driver add() functions were marked __init, but can be called any time until driver is unregistered (not a real problem until HPETs can be hotplugged) - time interpolator registration now done in driver add() path, so we can support removal of HPETs someday - physical MMIO address should be printed, not ioremapped address Signed-off-by:Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by:
