Commit 7b6d864b (reboot: arm: change reboot_mode to use enum reboot_mode) changed the way reboot is handled on arm, which has a direct impact on arm64 as we share the reset driver on the VE platform.

On arm64, cache maintenance faults appear as data aborts with the CM bit set in the ESR. The WnR bit, usually used to distinguish between faulting loads and stores, always reads as 1 and (slightly confusingly) the instructions are treated as reads by the architecture. This patch fixes our fault handling code to treat cache maintenance faults in the same way as loads.

During the pruning of the device tree octeon_fdt_pip_iface() is called for each PIP interface and every port up to the port count is removed from the device tree. However, the count was set to the return value of cvmx_helper_interface_enumerate() which doesn't actually return the count but just returns zero on success. This effectively removed *all* ports from the tree. Use cvmx_helper_ports_on_interface() instead to fix this. This successfully restores the 3 ports of my ERLite-3 and fixes the "kernel assigns random MAC addresses" issue.

Make KVM_GUEST depend on BROKEN_ON_SMP so that it cannot be enabled with SMP. SMP kernels use ll/sc instructions for an atomic section in the tlb fill handler, with a tlbp instruction contained in the middle.

Commit 4df715aa ["MIPS: BMIPS: support booting from physical CPU other than 0"] introduced a thinko which will prevents slave CPUs from being released from reset on systems where we boot from TP0. The problem is that we are checking whether the slave CPU logical CPU map is 0, which is never true for systems booting from TP0, so we do not release the slave TP from reset and we are just stuck. Fix this by properly checking that the CPU we intend to boot really is the physical slave CPU (logical and physical value being 1).

Currently, fast page fault incorrectly tries to fix mmio page fault when the generation number is invalid (spte.gen != kvm.gen). It then returns to guest to retry the fault since it sees the last spte is nonpresent. This causes an infinite loop. Since fast page fault only works for direct mmu, the issue exists when 1) tdp is enabled. It is only triggered only on AMD host since on Intel host the mmio page fault is recognized as ept-misconfig whose handler call fault-page path with error_code = 0 2) guest paging is disabled. Under this case, the issue is hardly discovered since paging disable is short-lived and the sptes will be invalid after memslot changed for 150 times Fix it by filtering out MMIO page faults in page_fault_can_be_fast.

Since the IDT is referenced from a fixmap, make sure it is page aligned. Merge with 32-bit one, since it was already aligned to deal with F00F bug. Since bss is cleared before IDT setup, it can live there. This also moves the other *_idt_table variables into common locations. This avoids the risk of the IDT ever being moved in the bss and having the mapping be offset, resulting in calling incorrect handlers. In the current upstream kernel this is not a manifested bug, but heavily patched kernels (such as those using the PaX patch series) did encounter this bug. The tables other than idt_table technically do not need to be page aligned, at least not at the current time, but using a common declaration avoids mistakes. On 64 bits the table is exactly one page long, anyway.

There are CPUs which have errata causing RDMSR of a nonexistent MSR to not fault. We would then try to WRMSR to restore the value of that MSR, causing a crash. Specifically, some Pentium M variants would have this problem trying to save and restore the non-existent EFER, causing a crash on resume. Work around this by making sure we can write back the result at suspend time. Huge thanks to Christian Sünkenberg for finding the offending erratum that finally deciphered the mystery.

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) are flagged as __cpuinit -- so if we remove the __cpuinit from arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the arch/x86 uses of the __cpuinit macros from all C files. x86 only had the one __CPUINIT used in assembly files, and it wasn't paired off with a .previous or a __FINIT, so we can delete it directly w/o any corresponding additional change there.
