* powerpc: Remove dead module_find_bug codeSteven Rostedt2008-08-181-15/+0
| | | | | | | | | | | | | | | | | | Doing some various "make randconfig", I came across an error when CONFIG_BUG was not set: arch/powerpc/kernel/module.c: In function 'module_find_bug': arch/powerpc/kernel/module.c:111: error: increment of pointer to unknown structure arch/powerpc/kernel/module.c:111: error: arithmetic on pointer to an incomplete type arch/powerpc/kernel/module.c:112: error: dereferencing pointer to incomplete type Looking further into this, I found that module_find_bug, defined in powerpc arch code, is not called anywhere, so this just removes it. There is a static module_find_bug in lib/bug.c but that is a separate issue. Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Add CMO enabled flag and paging space data to lparcfgRobert Jennings2008-08-181-0/+5
| | | | | | | | | | Add a field in lparcfg output to indicate whether the kernel is running on a dedicated or shared memory lpar. Added fields to show the paging space pool IDs and the CMO page size.

* powerpc: Fix CMM page loaning on 64k page kernel with 4k hardware pagesBrian King2008-08-181-2/+25
| | | | | | | | | | | | If the firmware page size used for collaborative memory overcommit is 4k, but the kernel is using 64k pages, the page loaning is currently broken as it only marks the first 4k page of each 64k page as loaned. This fixes this to iterate through each 4k page and mark them all as loaned/active.

* powerpc: Make CMO paging space pool ID and page size availableRobert Jennings2008-08-182-8/+42
| | | | | | | | | | During platform setup, save off the primary/secondary paging space pool IDs and the page size. Added accessors in hvcall.h for these variables. This is needed for a subsequent fix. Submitted-by: Robert Jennings <rcj@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Fix lockdep IRQ tracing bugBenjamin Herrenschmidt2008-08-181-2/+3
| | | | | | | | | A small bogon sneaked into the ppc64 lockdep support. A test is branching slightly off causing a clobbered register value to overwrite the irq state under some circumstances.

* powerpc: Fix TLB invalidation on boot on 32-bitRocky Craig2008-08-181-1/+1
| | | | | | | | | | | | | The intent of "flush_tlbs" is to invalidate all TLB entries by doing a TLB invalidate instruction for all pages in the address range 0 to 0x00400000. A loop counter is set up at the high value and decremented by page size. However, the loop is only done once as the sense of the conditional branch at the loop end does not match the setup/decrement. This fixes it to do the whole range by correcting the branch condition. Signed-off-by: Rocky Craig <rocky.craig@hp.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Fix loss of vdso on fork on 32-bitBenjamin Herrenschmidt2008-08-181-1/+0
| | | | | | | | | | | | | When we fork, init_new_context() improperly resets the vdso_base of the new context to 0. That means that the new process loses access to the vdso for signal trampolines. The initialization should be unnecessary anyway as the context on a fresh mm should be 0 in the first place and binfmt_elf will initialize that value for a newly loaded process.

It was supposed to be a run time idle=poll option to the user. But, it was indeed getting used during normal menu and ladder governor default case, with no special user setting (Reported by Linus Torvalds).

Adding some debugging output showed that ACPI calls acpi_os_map_memory phys ffff0000 size 65535 And ioremap/PAT does this check in 32bit, so addr+size wraps and the BUG in reserve_memtype() triggers incorrectly. BUG_ON(start >= end); /* end is exclusive */ But reserve_memtype already uses u64: int reserve_memtype(u64 start, u64 end, so the 32bit truncation must happen in the caller.
