* ARM: OMAP: abstract debug card setup (smc, leds)David Brownell2007-09-205-46/+98
| | | | | | | | | | | | | | | Additional cleanup for debug boards on H2/P2/H3/H4: move the init code that's not board-specific into a new file where it can be easily shared between all the different boards (avoiding code duplication, and making it easier to support more devices). Make H4 use that. This should be easy to drop in to the OMAP1 boards using these debug cards; the only difference seems to be that the p2 does an extra reset of the smc using the fpga (probably all boards could do that, if it's necessary) and doesn't use the gpio mux or request APIs.

* ARM: OMAP: omap2/gpmc updatesDavid Brownell2007-09-201-11/+22
| | | | | | | | | | | | | | | | | GPMC updates: - bugfixes: wrong/missing flags, omitted write, wrong test - don't map memory segments starting at zero - improve debug messaging - export gpmc_get_fclk_perio]d() since it's needed to calc timings - expect gpmc_cs_set_timings() caller to have initialized sync vs async Note that this API is glitchy; likely the best fix would be to add a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that holds one key aspect of the GPMC timings (the gpmc_fclk divisor, and sync vs. async == whether that divisor matters).

* | x86-64: page faults from user mode are always user faultsLinus Torvalds2007-09-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Randy Dunlap noticed an interesting "crashme" behaviour on his dual Prescott Xeon setup, where he gets page faults with the error code having a zero "user" bit, but the register state points back to user mode. This may be a CPU microcode buglet triggered by some strange instruction pattern that crashme generates, and loading a microcode update seems to possibly have fixed it. Regardless, we really should trust the register state more than the error code, since it's really the register state that determines whether we can actually send a signal, or whether we're in kernel mode and need to oops/kill the process in the case of a page fault.

* | uml: fix irqstack crashJeff Dike2007-09-193-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a crash caused by an interrupt coming in when an IRQ stack is being torn down. When this happens, handle_signal will loop, setting up the IRQ stack again because the tearing down had finished, and handling whatever signals had come in. However, to_irq_stack returns a mask of pending signals to be handled, plus bit zero is set if the IRQ stack was already active, and thus shouldn't be torn down. This causes a problem because when handle_signal goes around the loop, sig will be zero, and to_irq_stack will duly set bit zero in the returned mask, faking handle_signal into believing that it shouldn't tear down the IRQ stack and return thread_info pointers back to their original values. This will eventually cause a crash, as the IRQ stack thread_info will continue pointing to the original task_struct and an interrupt will look into it after it has been freed. The fix is to stop passing a signal number into to_irq_stack. Rather, the pending signals mask is initialized beforehand with the bit for sig already set. References to sig in to_irq_stack can be replaced with references to the mask.

* | uml: use correct type in BLKGETSIZE ioctlNicolas George2007-09-191-1/+2
|/ | | | | | | | | | | | | | | | | | | | | I found a type mismatch in UML that makes host block devices unusable as ubd devices on x86_64 and other 64 bits systems (segfault of the mm subsystem): In block/ioctl.c, the following lines show that the BLKGETSIZE ioctl expects a pointer to a long: case BLKGETSIZE: if ((bdev->bd_inode->i_size >> 9) > ~0UL) return -EFBIG; return put_ulong(arg, bdev->bd_inode->i_size >> 9); In arch/um/os-Linux/file.c, os_file_size calls it with an int.

* [SPARC64]: Fix lockdep, particularly on SMP.David S. Miller2007-09-163-26/+58
| | | | | | | | | | | | | | | | | | | | | | | As noted by Al Viro, when we try to call prom_set_trap_table() in the SMP trampoline code we try to take the PROM call spinlock which doesn't work because the current thread pointer isn't valid yet and lockdep depends upon that being correct. Furthermore, we cannot set the current thread pointer register because it can't be properly dereferenced until we return from prom_set_trap_table(). Kernel TLB misses only work after that call. So do the PROM call to set the trap table directly instead of going through the OBP library C code, and thus avoid the lock altogether. These calls are guarenteed to be serialized fully. Since there are now no calls to the prom_set_trap_table{_sun4v}() library functions, they can be deleted. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for processors that have cache-aliasing issues, such as the Stretch S5000 processor. Cache-aliasing means that the size of the cache (for one way) is larger than the page size, thus, a page can end up in several places in cache depending on the virtual to physical translation. The method used here is to map a user page temporarily through the auto-refill way 0 and of of the DTLB. We probably will want to revisit this issue and use a better approach with kmap/kunmap.
