2007-06-08m68knommu: fix ColdFire timer off by 1Greg Ungerer1-4/+6
The coldfire timer runs from 0 to TRR included, then 0 again and so on. It counts thus actually TRR + 1 steps for 1 tick, not TRR. Fix that.

2007-06-07enable interrupts in user path of page fault.Steven Rostedt2-0/+11
This is a minor fix, but what is currently there is essentially wrong. In do_page_fault, if the faulting address from user code happens to be in kernel address space (int *p = (int*)-1; p = 0xbed;) then the do_page_fault handler will jump over the local_irq_enable with the goto bad_area_nosemaphore; But the first line there sees this is user code and goes through the process of sending a signal to send SIGSEGV to the user task. This whole time interrupts are disabled and the task can not be preempted by a higher priority task. This patch always enables interrupts in the user path of the bad_area_nosemaphore.

2007-06-07[SPARC64]: Fix SBUS IRQ regression caused by PCI-E driver.David S. Miller2-54/+54
We used to access the 64-bit IRQ IMAP and ICLR registers of bus controllers 4-bytes in and as a 32-bit register word, since only the low 32-bits were relevant. This seemed like a good idea at the time. But the PCI-E controller requires full 8-byte 64-bit access to these registers, so we switched over to accessing them fully. SBUS was not adjusted properly, which broke interrupts completely. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-06-07[POWERPC] Fix building of COFF zImagesPaul Mackerras1-0/+1
The COFF zImage (for booting oldworld powermacs) wasn't being built correctly because the procedure descriptor in crt0.S for the zImage entry point wasn't declared as .globl, and therefore wasn't getting pulled in from wrapper.a by the linker. This adds the necessary .globl statement. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-07[POWERPC] spufs: Fix error handling in spufs_fill_dir()Sebastian Siewior1-2/+15
The error path in spufs_fill_dir() is broken. If d_alloc_name() or spufs_new_file() fails, spufs_prune_dir() is getting called. At this time dir->inode is not set and a NULL pointer is dereferenced by mutex_lock(). This bugfix replaces spufs_prune_dir() with a shorter version that does not touch dir->inode but simply removes all children.

We had a problem on a system with only dynamically allocated PCI buses (using of_pci_phb_driver) in combination with libata. This setup ended up having no "primary" phb, which means that pci_io_base never got initialized and all IO port numbers are 64 bit numbers, which is larger than the PIO_MASK limit.

2007-06-07[POWERPC] spufs scheduler: Fix wakeup racesChristoph Hellwig1-82/+77
Fix the race between checking for contexts on the runqueue and actually waking them in spu_deactive and spu_yield. The guts of spu_reschedule are split into a new helper called grab_runnable_context which shows if there is a runnable thread below a specified priority and if yes removes if from the runqueue and uses it. This function is used by the new __spu_deactivate hepler shared by preemption and spu_yield to grab a new context before deactivating a specified priority and if yes removes if from the runqueue and uses it. This function is used by the new __spu_deactivate hepler shared by preemption and spu_yield to grab a new context before deactivating the old one.

2007-06-07[POWERPC] spufs: Fix gang destroy leaksJeremy Kerr1-35/+5
Previously, closing a SPE gang that still has contexts would trigger a WARN_ON, and leak the allocated gang. This change fixes the problem by using the gang's reference counts to destroy the gang instead. The gangs will persist until their last reference (be it context or open file handle) is gone. Also, avoid using statements with side-effects in a WARN_ON().
