2018-01-08KVM: arm/arm64: Preserve Exec permission across R/W permission faultsMarc Zyngier
So far, we loose the Exec property whenever we take permission faults, as we always reconstruct the PTE/PMD from scratch. This can be counter productive as we can end-up with the following fault sequence: X -> RO -> ROX -> RW -> RWX Instead, we can lookup the existing PTE/PMD and clear the XN bit in the new entry if it was already cleared in the old one, leadig to a much nicer fault sequence: X -> ROX -> RWX Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2018-01-08KVM: arm/arm64: Limit icache invalidation to prefetch abortsMarc Zyngier
We've so far eagerly invalidated the icache, no matter how the page was faulted in (data or prefetch abort). But we can easily track execution by setting the XN bits in the S2 page tables, get the prefetch abort at HYP and perform the icache invalidation at that time only. As for most VMs, the instruction working set is pretty small compared to the data set, this is likely to save some traffic (specially as the invalidation is broadcast).

2018-01-08arm: KVM: Add optimized PIPT icache flushingMarc Zyngier
Calling __cpuc_coherent_user_range to invalidate the icache on a PIPT icache machine has some pointless overhead, as it starts by cleaning the dcache to the PoU, while we're guaranteed to have already cleaned it to the PoC. As KVM is the only user of such a feature, let's implement some ad-hoc cache flushing in kvm_mmu.h. Should it become useful to other subsystems, it can be moved to a more global location.

2018-01-08arm64: KVM: Add invalidate_icache_range helperMarc Zyngier
We currently tightly couple dcache clean with icache invalidation, but KVM could do without the initial flush to PoU, as we've already flushed things to PoC. Let's introduce invalidate_icache_range which is limited to invalidating the icache from the linear mapping (and thus has none of the userspace fault handling complexity), and wire it in KVM instead of flush_icache_range.

With TPM 2.0 specification, the event logs may only be accessible by calling an EFI Boot Service. Modify the EFI stub to copy the log area to a new Linux-specific EFI configuration table so it remains accessible once booted. When calling this service, it is possible to specify the expected format of the logs: TPM 1.2 (SHA1) or TPM 2.0 ("Crypto Agile"). For now, only the first format is retrieved.

2018-01-07RISC-V: Make __NR_riscv_flush_icache visible to userspacePalmer Dabbelt
We were hoping to avoid making this visible to userspace, but it looks like we're going to have to because QEMU's user-mode emulation doesn't want to emulate a vDSO. Having vDSO-only system calls was a bit unothodox anyway, so I think in this case it's OK to just make the actual system call number public. This patch simply moves the definition of __NR_riscv_flush_icache availiable to userspace, which results in the deletion of the now empty vdso-syscalls.h. Changes since v1: * I've moved the definition into uapi/asm/syscalls.h rathen than uapi/asm/unistd.h. This allows me to keep asm/unistd.h, so we can keep the syscall table macros sane. * As a side effect of the above, this no longer disables all system calls on RISC-V. Whoops!

2018-01-07ARM: dts: exynos: fix RTC interrupt for exynos5410Arnd Bergmann
According to the comment added to exynos_dt_pmu_match[] in commit 8b283c025443 ("ARM: exynos4/5: convert pmu wakeup to stacked domains"), the RTC is not able to wake up the system through the PMU on Exynos5410, unlike Exynos5420. However, when the RTC DT node got added, it was a straight copy of the Exynos5420 node, which now causes a warning from dtc. This removes the incorrect interrupt-parent, which should get the interrupt working and avoid the warning.

The new logical event is called cpu_thermal_margin. It comes with a unit and snapshot files. The event shows the current temprature distance (margin). It is not an accumulating event. The unit is degrees C. The event is provided per logical CPU to make things simpler but it is the same for both hyper-threads sharing a physical core. $ perf stat -I 1000 -a -A -e msr/cpu_thermal_margin/ This will print the temperature for all logical CPUs. time CPU counts unit events 1.000123741 CPU0 38 C msr/cpu_thermal_margin/ 1.000161837 CPU1 37 C msr/cpu_thermal_margin/ 1.000187906 CPU2 36 C msr/cpu_thermal_margin/ 1.000189046 CPU3 39 C msr/cpu_thermal_margin/ 1.000283044 CPU4 40 C msr/cpu_thermal_margin/ 1.000344297 CPU5 40 C msr/cpu_thermal_margin/ 1.000365832 CPU6 39 C msr/cpu_thermal_margin/ ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull more x86 pti fixes from Thomas Gleixner: "Another small stash of fixes for fallout from the PTI work: - Fix the modules vs. KASAN breakage which was caused by making MODULES_END depend of the fixmap size. That was done when the cpu entry area moved into the fixmap, but now that we have a separate map space for that this is causing more issues than it solves. - Use the proper cache flush methods for the debugstore buffers as they are mapped/unmapped during runtime and not statically mapped at boot time like the rest of the cpu entry area. - Make the map layout of the cpu_entry_area consistent for 4 and 5 level paging and fix the KASLR vaddr_end wreckage. - Use PER_CPU_EXPORT for per cpu variable and while at it unbreak nvidia gfx drivers by dropping the GPL export. The subject line of the commit tells it the other way around, but I noticed that too late. - Fix the ASM alternative macros so they can be used in the middle of an inline asm block. - Rename the BUG_CPU_INSECURE flag to BUG_CPU_MELTDOWN so the attack vector is properly identified. The Spectre mitigations will come with their own bug bits later" * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/pti: Rename BUG_CPU_INSECURE to BUG_CPU_MELTDOWN x86/alternatives: Add missing '\n' at end of ALTERNATIVE inline asm x86/tlb: Drop the _GPL from the cpu_tlbstate export x86/events/intel/ds: Use the proper cache flush method for mapping ds buffers x86/kaslr: Fix the vaddr_end mess x86/mm: Map cpu_entry_area at the same place on 4/5 level x86/mm: Set MODULES_END to 0xffffffffff000000
