2006-07-14[POWERPC] iseries: Move iommu_table_cb into platforms/iseriesMichael Ellerman
Although we pass the address of an iommu_table_cb to HvCallXm_getTceTableParms, we don't actually need the structure definition anywhere except in the iseries iommu code, so move the struct in there.

2006-07-13[POWERPC] Fix a compiler warning in mm/tlb_64.cMichael Ellerman
The compiler doesn't understand that BUG() never returns, so complains that psize isn't set. Just set it to the normal value, which seems to produce nice code and keeps gcc happy. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2006-07-13[POWERPC] iseries: Fix a compiler warning in platforms/iseries/vpdinfo.cMichael Ellerman
iSeries_Get_Location_Code() has error paths, but currently returns void, so give it a return code and only print the output if it returns successfully. Gcc isn't smart enough to be quiet though, so set frame to 0 to shut it up. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2006-07-13[POWERPC] iseries: Make ItExtVpdPanel private to iSeriesMichael Ellerman
No one outside platforms/iseries needs ItExtVpdPanel anymore, so move it in there. It used to be needed by lparcfg, and so was exported, but isn't needed anymore, so unexport it. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2006-07-13[POWERPC] iseries: Cleanup e2a() and strne2a()Michael Ellerman
e2a() was formally used by lparcfg, and so had to be exported, but isn't anymore, so don't. e2a() and strne2a() can both be static, and __init. And e2a can be made much more concise if we use x ... y case labels, while we're there add support for lower case letters.

2006-07-13[POWERPC] iseries: Use device tree /system-id in /proc/iSeries/configMichael Ellerman
We export a bunch of info in /proc/iSeries/config. Currently we pull it directly out of some iSeries specific structs, but we could use the device tree instead, this saves decoding it twice and is a little neater.

2006-07-07[POWERPC] Add cpufreq support for Xserve G5Benjamin Herrenschmidt
The Xserve G5 are capable of frequency switching like other desktop G5s. This enables it. It also fix a Kconfig issue which prevented from building the G5 cpufreq support if CONFIG_PMAC_SMU was not set (the first version of that driver only worked with SMU based macs, but this isn't the case anymore).

2006-07-07[POWERPC] Fix mem= handling when the memory limit is > RMO sizeMichael Ellerman
There's a bug in my cleaned up mem= handling, if the memory limit is larger than the RMO size we'll erroneously enlarge the RMO size.

2006-07-07[POWERPC] More offb/bootx fixesBenjamin Herrenschmidt
There were still some issues with offb when BootX doesn't provide a proper display node, this fixes them. This also re-instates the palette hacks that were disabled a couple of kernel versions ago when I converted to the new OF parsing, and shuffles some functions around to avoid prototypes.

2006-07-07[POWERPC] Fix legacy_serial.c error handling on 32 bitsBenjamin Herrenschmidt
The code in legacy_serial.c wouldn't properly compare OF translation results against OF_BAD_ADDR as it's using a phys_addr_t which is 32 bits on some 32-bit powerpc platforms. This fixes it by always using a u64 which is what is returned by the OF parsing routines. It also makes translation failure harmless for ISA serial ports. If they can't translate, we can't use the UART early, but we can still let the 8250 driver use it later on by using IO port accessors.

2006-07-07[POWERPC] Fix non-MPIC CHRPs with CONFIG_SMP setBenjamin Herrenschmidt
Pseudo-CHRP machines like Pegasos without an MPIC would crash at boot if CONFIG_SMP was set because the "smp_ops" pointer was set to MPIC related ops unconditionally. This patch makes it NULL on machines that don't support SMP and provides proper default behaviour in the callers when smp_ops is NULL.

2006-07-07[POWERPC] Workaround Pegasos incorrect ISA "ranges"Benjamin Herrenschmidt

2006-07-05[PATCH] powerpc: Fix loss of interrupts with MPICBenjamin Herrenschmidt
With the new interrupt rework, an interrupt "host" map() callback can be called after the interrupt is already active. It's called again for an already mapped interrupt to allow changing the trigger setup, and currently this is not guarded with a test of wether the interrupt is requested or not. I plan to change some of this logic to be a bit less lenient against random reconfiguring of live interrupts but just not yet. The ported MPIC driver has a bug where when that happens, it will mask the interrupt. This changes it to preserve the previous masking of the interrupt instead.

2006-07-04[PATCH] Fix copying of pgdat array on each node for ia64 memory hotplugYasunori Goto
I found a bug in memory hot-add code for ia64. IA64's code has copies of pgdat's array on each node to reduce memory access over crossing node. This array is used by NODE_DATA() macro. When new node is hot-added, this pgdat's array should be updated and copied on new node too. However, I used for_each_online_node() in scatter_node_data() to copy it. This meant its array is not copied on new node. Because initialization of structures for new node was halfway, so online_node_map couldn't be set at this time. To copy arrays on new node, I changed it to check value of pgdat_list[] which is source array of copies. I tested this patch with my Memory Hotadd emulation on Tiger4. This patch is for 2.6.17-git20.

2006-07-03[PATCH] lockdep: irqtrace subsystem, move account_system_vtime() calls into ↵Paul Mackerras
kernel/softirq.c At the moment, powerpc and s390 have their own versions of do_softirq which include local_bh_disable() and __local_bh_enable() calls. They end up calling __do_softirq (in kernel/softirq.c) which also does local_bh_disable/enable. Apparently the two levels of disable/enable trigger a warning from some validation code that Ingo is working on, and he would like to see the outer level removed. But to do that, we have to move the account_system_vtime calls that are currently in the arch do_softirq() implementations for powerpc and s390 into the generic __do_softirq() (this is a no-op for other archs because account_system_vtime is defined to be an empty inline function on all other archs).
