| * agp: convert drivers/char/agp/frontend.c to use unlocked_ioctlMathieu Segaud2008-04-261-2/+2
| | | | | | | | | | | | | | | | | | | | 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.

| * | x86: introduce /dev/mem restrictions with a config optionArjan van de Ven2008-04-241-0/+28
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | | | [POWERPC] Xilinx: hwicap: Verify sync before reading idcode.Stephen Neuendorffer2008-03-261-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears that in some cases, the sync word might not be recognized by the hardware correctly. If this happens, then attempting to read from the port results in an unrecoverable error because of the design of the FPGA core. This patch updates the code to check the status of the device before reading the IDCODE, in order to avoid entering this unrecoverable state. This patch also adds additional NOOP commands into the sychronization sequence, which appears to be necessary to avoid the condition on some hardware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both the buffer-based and fifo-based icap cores have a status register. Previously, this was only used internally to check whether transactions have completed. However, the status can be useful to the main driver as well. This patch exposes these status functions to the main driver along with some masks for the differnet bits.

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.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
