2009-04-07ramfs: fix double freeing s_fs_info on failed mountIngo Molnar
If ramfs mount fails, s_fs_info will be freed twice in ramfs_fill_super() and ramfs_kill_sb(), leading to kernel oops. Consolidate and beautify the code. Make sure s_fs_info and s_root are in known good states.

2009-04-07powerpc: Fix oops when loading modulesPaul Mackerras
This fixes a problem reported by Sean MacLennan where loading any module would cause an oops. We weren't marking the pages containing the module text as having hardware execute permission, due to a bug introduced in commit 8d1cf34e ("powerpc/mm: Tweak PTE bit combination definitions"), hence trying to execute the module text caused an exception on processors that support hardware execute permission. This adds _PAGE_HWEXEC to the definitions of PAGE_KERNEL_X and PAGE_KERNEL_ROX to fix this problem.

2009-04-07powerpc: Fix ptrace compat wrapper for FPU register accessMichael Neuling
The ptrace compat wrapper mishandles access to the fpu registers. The PTRACE_PEEKUSR and PTRACE_POKEUSR requests miscalculate the index into the fpr array due to the broken FPINDEX macro. The PPC_PTRACE_PEEKUSR_3264 request needs to use the same formula that the native ptrace interface uses when operating on the register number (as opposed to the 4-byte offset). The PPC_PTRACE_POKEUSR_3264 request didn't take TS_FPRWIDTH into account.

2009-04-07powerpc: Print information about mapping hw irqs to virtual irqsMichael Ellerman
The irq remapping layer seems to cause some confusion when people see a different irq number in /proc/interrupts vs the one they request in their driver or DTS. So have the irq remapping layer print out a message when we map an irq. The message is only printed the first time the irq is mapped, and it's KERN_DEBUG so most people won't see it.

2009-04-07powerpc: Disable VSX or current process in giveup_fpu/altivecMichael Neuling
When we call giveup_fpu, we need to need to turn off VSX for the current process. If we don't, on return to userspace it may execute a VSX instruction before the next FP instruction, and not have its register state refreshed correctly from the thread_struct. Ditto for altivec. This caused a bug where an unaligned lfs or stfs results in fix_alignment calling giveup_fpu so it can use the FPRs (in order to do a single <-> double conversion), and then returning to userspace with FP off but VSX on. Then if a VSX instruction is executed, before another FP instruction, it will proceed without another exception and hence have the incorrect register state for VSX registers 0-31. lfs unaligned <- alignment exception turns FP off but leaves VSX on VSX instruction <- no exception since VSX on, hence we get the wrong VSX register values for VSX registers 0-31, which overlap the FPRs.

2009-04-07powerpc/pmac: Fix internal modem IRQ on Wallstreet PowerBookBenjamin Herrenschmidt
The (relatively) new pmac_zilog driver doesn't use the pre-munged IRQ numbers from the macio_dev unlike other macio things, it directly maps it off the OF device-tree. It does that because it can be initialized much earlier than the registration of the macio devices, in order to get a serial console early. Unfortunately, that means that it "misses" some fixups done by the macio layer to work around missing interrupt descriptions in the device-tree of the Wallstreet machines. This patch brings the necessary workaround into the pmac_zilog driver itself to bring it back to working condition.

2009-04-07powerpc/wdrtas: Update wdrtas_get_interval to use rtas_data_bufMark Nelson
The buffer passed to the ibm,get-system-parameter RTAS call must be in the RMA. To ensure we pass an address in the RMA use rtas_data_buf for the actual RTAS call and then copy the result to value. We can't just make it static because this can be compiled in as a module. Also add the WDRTAS_SP_SPI_LEN so we don't litter '4' throughout the function.
