[PARISC] pdc_init no longer exists

2006-10-07T11:22:30+00:00

Just a stale prototype

[PARISC] Make DMA routines more stubby

2006-10-04T12:51:07+00:00

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.

[PARISC] Define pci_get_legacy_ide_irq

2006-10-04T12:50:55+00:00

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.

[PARISC] Fix iounmap compile warning

2006-10-04T12:50:26+00:00

iounmap's argument needs to be both const and volatile, otherwise we'll
get warnings that we're discarding pointer qualifiers

[PARISC] Add support for Quicksilver AGPGART

[PARISC] Move LBA and SBA register defines to the common ropes.h

2006-10-04T12:50:05+00:00

header. This will allow the use of more constants in the
agpgart driver.

[PARISC] Create shared header

2006-10-04T12:49:56+00:00

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)

[PARISC] Allow nested interrupts

2006-10-04T12:48:57+00:00

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.

[PARISC] Enable interrupts while spinning

2006-10-04T12:48:17+00:00

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
