git://git.kernel.org/pub/scm/linux/kernel/git/airlied/agp-2.6 * 'agp-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/agp-2.6: agp: convert drivers/char/agp/frontend.c to use unlocked_ioctl agp: fix shadowed variable warning in amd-k7-agp.c
2008-04-26agp: convert drivers/char/agp/frontend.c to use unlocked_ioctlMathieu Segaud
As of now, agp_compat_ioctl already runs without the BKL. Mutual exclusion is enforced by agp_fe.agp_mutex in agp_ioctl() and agp_compat_ioctl(). Apply the same locking rationale to the two functions allowing BKL cleanup.

2008-04-24x86: introduce /dev/mem restrictions with a config optionArjan van de Ven
This patch introduces a restriction on /dev/mem: Only non-memory can be read or written unless the newly introduced config option is set. The X server needs access to /dev/mem for the PCI space, but it doesn't need access to memory; both the file permissions and SELinux permissions of /dev/mem just make X effectively super-super powerful. With the exception of the BIOS area, there's just no valid app that uses /dev/mem on actual memory. Other popular users of /dev/mem are rootkits and the like. (note: mmap access of memory via /dev/mem was already not allowed since a really long time) People who want to use /dev/mem for kernel debugging can enable the config option. The restrictions of this patch have been in the Fedora and RHEL kernels for at least 4 years without any problems.

2008-04-24arm/mach-integrator/time.c, mwave: revert portions of recent irq cleanupsJeff Garzik
The recent irq cleanups for arch/arm/mach-integrator/time.c and drivers/char/mwave/tp3780i.c changed the request_irq() dev_id parameter, but neglected to change the matching free_irq() parameter, thus creating a bug upon irq de-registration. Given that the impetus for the changes is not yet accepted upstream, it is best to revert the irq cleanups. Mostly. A comment is added to time.c to reduce future confusion, of type that led to my time.c cleanup in the first place. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-04-19PM: Remove destroy_suspended_device()Rafael J. Wysocki
After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by: Rafael J.

2008-04-17[S390] hw_random: allow rng_dev_read() to return hardware errors.Ralph Wuerthner
The api for hardware random number generators is currently limited to devices that never fail. If the hardware is registered as a source for random numbers it has to work. This prevents the use of i/o based random number devices where the i/o might fail. Add a check for errors after the read from a hardware random number device. This patch is required to support large random numbers retrieved from the CEX2C cards on System z.

2008-04-17[POWERPC] hvcbeat: Fix buffer manipulationIshizaki Kou
This fixes a potential bug at drivers/char/hvc_beat.c. - hvc_put_term_char routine will decrement "rest" variable twice, and forget to advance "buf" pointer by "nlen" bytes. This bug was not hit previously because the output handler in drivers/char/hvc_console.c splits given output into 16 bytes at maximum.

Led state should be part of the key event, like shiftstate, and not grabbed asynchronously after the fact.

2008-04-06fix IS_I9XX macro in i915 DRM driverJesse Barnes
Now that we're mapping registers in the DRM driver at load time, the driver actually checks the PCI ID, so we need to make sure the macros have all the right bits (and longer term use the DRM headers as the sole copy of the PCI & register definitions). This patch adds 945GME support to the DRM headers, fixing a regression reported in http://bugzilla.kernel.org/show_bug.cgi?id=10395.
