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.

PCI still doesn't work on sh7785lcr 29bit 256M map mode. On SH7785, PCI -> SHwy address translation is not base+offset but somewhat like base|offset (See HW Manual (rej09b0261) Fig. 13.11). So, you can't export CS2,3,4,5 by 256M at CS2 (results CS0,1,2,3 exported, I guess). There are two candidates. a) 128M@CS2 + 128M@CS4 b) 512M@CS0 Attached patch is B. It maps 512M Byte at 0 independently of memory size. It results CS0 to CS6 and perhaps some more being accessible from PCI.

2009-04-04sh: Fix up DSP context save/restore.Michael Trimarchi
There were a number of issues with the DSP context save/restore code, mostly left-over relics from when it was introduced on SH3-DSP with little follow-up testing, resulting in things like task_pt_dspregs() referencing incorrect state on the stack. This follows the MIPS convention of tracking the DSP state in the thread_struct and handling the state save/restore in switch_to() and finish_arch_switch() respectively. The regset interface is also updated, which allows us to finally be rid of task_pt_dspregs() and the special cased task_pt_regs().

This is the same case even for NMI structure reporting. The Processor X2APIC Affinity structure provides the association between the X2APIC ID of a logical processor and the proximity domain to which the logical processor belongs. For OSPM, Procssor IDs outside the 0-254 range are to be declared as Device() objects in the ACPI namespace.

2009-04-03x86, PAT: Remove duplicate memtype reserve in pci mmapSuresh Siddha
pci mmap code was doing memtype reserve for a while now. Recently we added memtype tracking in remap_pfn_range, and pci code indirectly calls remap_pfn_range. So, we don't need seperate tracking in pci code anymore. Which means a patch that removes ~50 lines of code :-). Also, recently we found out that the pci tracking is not working as we expect it to work in some cases. Specifically, userlevel X mmap of pci, with some recent version of X, is having a problem with vm_page_prot getting reset. The pci tracking uses vm_page_prot to pass on the protection type from parent to child during fork. a) Parent does a pci mmap b) We look at PAT and get either UC_MINUS or WC mapping for parent c) Store that mapping type in vma vm_page_prot for future use d) This thread does a fork e) Fork results in mmap_ops ->open for the child process f) We get the vm_page_prot from vma and reserve that type for the child process But, between c) and e) above, the vma vm_page_prot is getting reset to zero. This results in PAT reserve failing at the time of fork as in here. http://marc.info/?l=linux-kernel&m=123858163103240&w=2 This cleanup makes the above problem go away as we do not depend on vm_page_prot in our PAT code anymore.

2009-04-03x86: disable stack-protector for __restore_processor_state()Joseph Cihula
The __restore_processor_state() fn restores %gs on resume from S3. As such, it cannot be protected by the stack-protector guard since %gs will not be correct on function entry. There are only a few other fns in this file and it should not negatively impact kernel security that they will also have the stack-protector guard removed (and so it's not worth moving them to another file). Without this change, S3 resume on a kernel built with CONFIG_CC_STACKPROTECTOR_ALL=y will fail.
