Linus Torvalds cfaa9f029f Merge branch 'spectre' of git://git.armlinux.org.uk/~rmk/linux-arm ... Pull ARM spectre updates from Russell King: "These are the currently known final bits that resolve the Spectre issues. big.Little systems used to be sufficiently identical in that there were no differences between individual CPUs in the system that mattered to the kernel. With the advent of the Spectre problem, the CPUs now have differences in how the workaround is applied. As a result of previous Spectre patches, these systems ended up reporting quite a lot of: "CPUx: Spectre v2: incorrect context switching function, system vulnerable" messages due to the action of the big.Little switcher causing the CPUs to be re-initialised regularly. This series resolves that issue by making the CPU vtable unique to each CPU. However, since this is used very early, before per-cpu is setup, per-cpu can't be used. We also have a problem that two of the methods are not called from preempt-safe paths, but thankfully these remain identical between all CPUs in the system. To make sure, we validate that these are identical during boot" * 'spectre' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: spectre-v2: per-CPU vtables to work around big.Little systems ARM: add PROC_VTABLE and PROC_TABLE macros ARM: clean up per-processor check_bugs method call ARM: split out processor lookup ARM: make lookup_processor_type() non-__init		2018-11-18 10:45:09 -08:00
