* [PARISC] Add new function to start local Interval Timer, start_cpu_itimer()Grant Grundler2006-10-042-10/+14
| | | | | | | | | | | | | | 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).

* [PARISC] Prevent processor_probe() from clobbering cpu_data[0]Grant Grundler2006-10-041-2/+3

* [PARISC] Use CONFIG_HZ to determine interval timer rate (aka clock ticks)Grant Grundler2006-10-041-7/+3
| | | | | | | | | 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>

* [PARISC] Clean up asm-parisc/serial.hMatthew Wilcox2006-10-042-16/+4
| | | | | | | | | Russell King pointed out that asm/serial.h is anachronistic and we were misusing BASE_BAUD. So fix BASE_BAUD for PCI 16550 UARTs, move LASI_BASE_BAUD into 8250_gsc, and fix the obsolete comment about reserving serial port slots.

* [PARISC] parisc specific kmap API implementation for pa8800James Bottomley2006-10-044-23/+87
| | | | | | | | | | | | | | | | 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.

* [PARISC] PA7200 also supports prefetch for readKyle McMartin2006-10-042-1/+4
| | | | | | | | | 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>
* [PARISC] Untangle <asm/processor.h> header include messKyle McMartin2006-10-042-26/+38
| | | | | | | | | | | | | | | 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.
