2006-10-04[PARISC] Make DMA routines more stubbyMatthew Wilcox
We were pretending to use the GENERIC_ISA_DMA routines, but never selected that symbol. Since ISA DMA is known to not work right now, just remove the attempts to acquire the dma_spin_lock to fix compile warnings.

2006-10-04[PARISC] Define pci_get_legacy_ide_irqMatthew Wilcox
We can compile at least one IDE driver that refers to this. We can't use the asm-generic file because we have our own definitions of pcibios_resource_to_bus etc. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-10-04[PARISC] Fix CONFIG_DEBUG_SPINLOCKMatthew Wilcox
Joel Soete points out that we refer to pa_tlb_lock but only define it if CONFIG_SMP which breaks a uniprocessor build with CONFIG_DEBUG_SPINLOCK enabled. No module refers to pa_tlb_lock, so we can delete the export. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

Pull out struct sba_device and struct lba_device into a common ropes.h header. Also fold the parisc portion of iosapic.h into this file. (Then delete the useless portion of iosapic.h) Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2006-10-04[PARISC] Allow nested interruptsJames Bottomley
Our prior mode of operation didn't allow nested interrupts because it makes the interrupt code much simpler. However, nested interrupts are better for latency. This code uses the EIEM register to simulate level interrupts and thus achieve nesting.

2006-10-04[PARISC] Further updates to timer_interrupt()Grant Grundler
This version (relative to the current tree): o eliminates "while (ticks_elapsed)" loop. It's not needed. o drop "ticks_elapsed" completely from timer_interrupt(). o Estimates elapsed cycles (based on HZ) to see which kind of math we want to use to calculate "cycles_remainder". o Fixes a bug where we would loose a tick if we decided we wanted to skip one interrupt.

2006-10-04[PARISC] Rewrite timer_interrupt() and gettimeoffset() using "unsigned" math.Grant Grundler
It's just a bit easier to follow and timer code is complex enough. So far, only tested on A500-5x (64-bit SMP), ie: gettimeoffset() code hasn't been tested at all. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-10-04[PARISC] Enable interrupts while spinningMatthew Wilcox
Use the __raw_spin_lock_flags routine so we can take an interrupt while spinning. This re-fixes a bug jejb found on 2005-10-20: CPU0 does a flush_tlb_all holding the vmlist_lock for write. CPU1 tries a cat of /proc/meminfo which tries to acquire vmlist_lock for read CPU1 is now spinning with interrupts disabled CPU0 tries to execute a smp_call_function to flush the local tlb caches This is now a deadlock because CPU1 is spinning with interrupts disabled and can never receive the IPI Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-10-04[PARISC] Add new function to start local Interval Timer, start_cpu_itimer()Grant Grundler
I couldn't find where the itimer was getting started for slave CPUs. CPU 0 (master) itimer was started in time_init() (arch/parisc/kernel/time.c). start_cpu_itimer() code was striped from time_init(). Slaves now start their itimer in smp_cpu_init(). This is a first step towards making gettimeoffset() work for SMP. Next step will be to determine the CR16 (cycle counter) offsets for each CPU relative to the master (CPU 0).

2006-10-04[PARISC] Prevent processor_probe() from clobbering cpu_data[0]Grant Grundler
processor_probe() shouldn't clobber cpu_data[0] cpu_data[0].it_value (used by timer_interrupt()) is already set. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-10-04[PARISC] Use CONFIG_HZ to determine interval timer rate (aka clock ticks)Grant Grundler
This isn't likely to be causing problems for other bits of kernel code. I can't find any other user of CONFIG_HZ outside of arch specific code. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2006-10-04[PARISC] Clean up asm-parisc/serial.hMatthew Wilcox
Russell King pointed out that asm/serial.h is anachronistic and we were misusing BASE_BAUD.

2006-10-04[PARISC] parisc specific kmap API implementation for pa8800James Bottomley
This patch fixes the pa8800 at a gross level (there are still other subtle incoherency issues which can still cause crashes and HPMCs). What it does is try to force eject inequivalent aliases before they become visible to the L2 cache (which is where we get the incoherence problems). A new function (parisc_requires_coherency) is introduced in asm/processor.h to identify the pa8x00 processors (8800 and 8900) which have the issue.

2006-10-04[PARISC] PA7200 also supports prefetch for readKyle McMartin
It seems PA7200 processors also suppress traps on loads to %r0. This means we can prefetch for read on these cpus. Of course, we can't support prefetch for write, since that requires LOAD DOUBLEWORD which was added with PA2.0 Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-10-04[PARISC] Untangle <asm/processor.h> header include messKyle McMartin
asm/processor.h on parisc wants spinlocks for cpuinfo, but linux/spinlock_types.h needs lockdep, and lockdep wants prefetch. This leads to a horrible circular dependancy, because <asm/processor.h> is including something which depends on things which are not defined until the end of the file. Kludge around this by moving prefetch related code into <asm/prefetch.h> and including it before <linux/spinlock_types.h>, however this is just a temporary solution until this mess can be cleaned up.

Currently the kernel audit system represents arch's as numbers and will gladly accept comparisons between archs using >, <, >=, <= when the only thing that makes sense is = or !=. I'm told that the next revision of auditctl will do this checking but this will provide enforcement in the kernel even for old userspace.
