2006-01-13[PATCH] powerpc: Remove lppaca structure from the PACADavid Gibson
At present the lppaca - the structure shared with the iSeries hypervisor and phyp - is contained within the PACA, our own low-level per-cpu structure. This doesn't have to be so, the patch below removes it, making a separate array of lppaca structures. This saves approximately 500*NR_CPUS bytes of image size and kernel memory, because we don't need aligning gap between the Linux and hypervisor portions of every PACA. On the other hand it means an extra level of dereference in many accesses to the lppaca. The patch also gets rid of several places where we assign the paca address to a local variable for no particular reason.

2006-01-12[PATCH] powerpc: iSeries fixes for build with no PCIStephen Rothwell
This reverts part of "ppc64 iSeries: allow build with no PCI" (145d01e4287b8cbf50f87c3283e33bf5c84e8468) which affected generic code and applies a fix in the arch specific code. Commit "partly merge iseries do_IRQ" (5fee9b3b39eb55c7e3619a3b36ceeabffeb8f144) introduced iSeries_get_irq which was only available if CONFIG_PCI is set.

2006-01-09powerpc: more iseries irq workStephen Rothwell
Make get_IRQ return a pending irq number so it can be handled in the powerpc geeneric code. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2006-01-09powerpc: partly merge iseries do_IRQStephen Rothwell
Hide some of the iseries details in iSeries_get_irq. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2006-01-09powerpc: use end_IRQ for iseries irqsStephen Rothwell
Encode the sub bus number into the real irq number (even though it is always zero for now) so that we have enough information to do the EOI in iseries_end_IRQ. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

Remove two useless counters. DeStropify. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-11-09ppc64: remove ppc_irq_dispatch_handlerStephen Rothwell
Use __do_IRQ instead. The only difference is that every controller is now assumed to have an end() routine (only xics_8259 did not). Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-11-07[PATCH] powerpc: Kill ppcdebugDavid Gibson
The ancient ppcdebug/PPCDBG mechanism is now only used in two places. First, in the hash setup code, one of the bits allows the size of the hash table to be reduced by a factor of 8 - which would be better accomplished with a command line option for that purpose. The other was a bunch of bus walking related messages in the iSeries code, which would seem to be insufficient reason to keep the mechanism. This patch removes the last traces of this mechanism. Built and booted on iSeries and pSeries POWER5 LPAR (ARCH=powerpc). Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
