This reworks kvmppc_mmu_book3s_64_xlate() to make it check the large page bit in the hashed page table entries (HPTEs) it looks at, and to simplify and streamline the code. The checking of the first dword of each HPTE is now done with a single mask and compare operation, and all the code dealing with the matching HPTE, if we find one, is consolidated in one place in the main line of the function flow.

It turns out that if we exit the guest due to a hcall instruction (sc 1), and the loading of the instruction in the guest exit path fails for any reason, the call to kvmppc_ld() in kvmppc_get_last_inst() fetches the instruction after the hcall instruction rather than the hcall itself. This in turn means that the instruction doesn't get recognized as an hcall in kvmppc_handle_exit_pr() but gets passed to the guest kernel as a sc instruction. That usually results in the guest kernel getting a return code of 38 (ENOSYS) from an hcall, which often triggers a BUG_ON() or other failure. This fixes the problem by adding a new variant of kvmppc_get_last_inst() called kvmppc_get_last_sc(), which fetches the instruction if necessary from pc - 4 rather than pc.

Currently the code assumes that once we load up guest FP/VSX or VMX state into the CPU, it stays valid in the CPU registers until we explicitly flush it to the thread_struct. However, on POWER7, copy_page() and memcpy() can use VMX. These functions do flush the VMX state to the thread_struct before using VMX instructions, but if this happens while we have guest state in the VMX registers, and we then re-enter the guest, we don't reload the VMX state from the thread_struct, leading to guest corruption. This has been observed to cause guest processes to segfault. To fix this, we check before re-entering the guest that all of the bits corresponding to facilities owned by the guest, as expressed in vcpu->arch.guest_owned_ext, are set in current->thread.regs->msr. Any bits that have been cleared correspond to facilities that have been used by kernel code and thus flushed to the thread_struct, so for them we reload the state from the thread_struct. We also need to check current->thread.regs->msr before calling giveup_fpu() or giveup_altivec(), since if the relevant bit is clear, the state has already been flushed to the thread_struct and to flush it again would corrupt it.

Unlike the other general-purpose SPRs, SPRG3 can be read by usermode code, and is used in recent kernels to store the CPU and NUMA node numbers so that they can be read by VDSO functions. Thus we need to load the guest's SPRG3 value into the real SPRG3 register when entering the guest, and restore the host's value when exiting the guest. We don't need to save the guest SPRG3 value when exiting the guest as usermode code can't modify SPRG3.

Currently this is only being done on 64-bit. Rather than just move it out of the 64-bit ifdef, move it to kvm_lazy_ee_enable() so that it is consistent with lazy ee state, and so that we don't track more host code as interrupts-enabled than necessary.

The table of offsets to real-mode hcall handlers in book3s_hv_rmhandlers.S can contain negative values, if some of the handlers end up before the table in the vmlinux binary. Thus we need to use a sign-extending load to read the values in the table rather than a zero-extending load. Without this, the host crashes when the guest does one of the hcalls with negative offsets, due to jumping to a bogus address.

This corrects the usage of the tlbie (TLB invalidate entry) instruction in HV KVM. The tlbie instruction changed between PPC970 and POWER7. On the PPC970, the bit to select large vs. small page is in the instruction, not in the RB register value. This changes the code to use the correct form on PPC970. On POWER7 we were calculating the AVAL (Abbreviated Virtual Address, Lower) field of the RB value incorrectly for 64k pages. This fixes it. Since we now have several cases to handle for the tlbie instruction, this factors out the code to do a sequence of tlbies into a new function, do_tlbies(), and calls that from the various places where the code was doing tlbie instructions inline. It also makes kvmppc_h_bulk_remove() use the same global_invalidates() function for determining whether to do local or global TLB invalidations as is used in other places, for consistency, and also to make sure that kvm->arch.need_tlb_flush gets updated properly.

Powerpc architecture uses a hash based page table mechanism for mapping virtual addresses to physical address. The architecture require this hash page table to be physically contiguous. With KVM on Powerpc currently we use early reservation mechanism for allocating guest hash page table. This implies that we need to reserve a big memory region to ensure we can create large number of guest simultaneously with KVM on Power. Another disadvantage is that the reserved memory is not available to rest of the subsystems and and that implies we limit the total available memory in the host. This patch series switch the guest hash page table allocation to use contiguous memory allocator.

Pull first batch of ARC changes from Vineet Gupta: "There's a second bunch to follow next week - which depends on commits on other trees (irq/net). I'd have preferred the accompanying ARC change via respective trees, but it didn't workout somehow. Highlights of changes: - Continuation of ARC MM changes from 3.10 including zero page optimization Setting pagecache pages dirty by default Non executable stack by default Reducing dcache flushes for aliasing VIPT config - Long overdue rework of pt_regs machinery - removing the unused word gutters and adding ECR register to baseline (helps cleanup lot of low level code) - Support for ARC gcc 4.8 - Few other preventive fixes, cosmetics, usage of Kconfig helper..

Pull ARM updates from Russell King: "This contains the usual updates from other people (listed below) and the usual random muddle of miscellaneous ARM updates which cover some low priority bug fixes and performance improvements. I've started to put the pull request wording into the merge commits, which are: - NoMMU stuff: This includes the following series sent earlier to the list: - nommu-fixes - R7 Support - MPU support I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I were discussing today until we've reached a conclusion/that's had some more review. This is rebased (and re-tested) on your devel-stable branch because otherwise there were going to be conflicts with Uwe's V7M work now that you've merged that. I've included the fix for limiting MPU to CPU_V7. - Huge page support These changes bring both HugeTLB support and Transparent HugePage (THP) support to ARM. Only long descriptors (LPAE) are supported in this series. The code has been tested on an Arndale board (Exynos 5250). - LPAE updates Please pull these miscellaneous LPAE fixes I've been collecting for a while now for 3.11. They've been tested and reviewed by quite a few people, and most of the patches are pretty trivial. -- Will Deacon. - arch_timer cleanups Please pull these arch_timer cleanups I've been holding onto for a while. They're the same as my last posting, but have been rebased to v3.10-rc3. - mpidr linearisation (multiprocessor id register - identifies which CPU number we are in the system) This patch series that implements MPIDR linearization through a simple hashing algorithm and updates current cpu_{suspend}/{resume} code to use the newly created hash structures to retrieve context pointers. It represents a stepping stone for the implementation of power management code on forthcoming multi-cluster ARM systems. It has been tested on TC2 (dual cluster A15xA7 system), iMX6q, OMAP4 and Tegra, with processors hitting low-power states requiring warm-boot resume through the cpu_resume code path" * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (77 commits) ARM: 7775/1: mm: Remove do_sect_fault from LPAE code ARM: 7777/1: Avoid extra calls to the C compiler ARM: 7774/1: Fix dtb dependency to use order-only prerequisites ARM: 7770/1: remove residual ARMv2 support from decompressor ARM: 7769/1: Cortex-A15: fix erratum 798181 implementation ARM: 7768/1: prevent risks of out-of-bound access in ASID allocator ARM: 7767/1: let the ASID allocator handle suspended animation ARM: 7766/1: versatile: don't mark pen as __INIT ARM: 7765/1: perf: Record the user-mode PC in the call chain.
