Linux kernel development work - see feature branches https://git.zx2c4.com/linux-dev/atom/arch/powerpc/include/asm/cpu_setup_power.h?h=linus%2Fmaster 2020-11-19T03:49:56Z 2020-11-19T03:49:56Z Jordan Niethe jniethe5@gmail.com 2020-10-14T07:28:37Z urn:sha1:344fbab991a568dc33ad90711b489d870e18d26d The only thing keeping the cpu_setup() and cpu_restore() functions used in the cputable entries for Power7, Power8, Power9 and Power10 in assembly was cpu_restore() being called before there was a stack in generic_secondary_smp_init(). Commit ("powerpc/64: Set up a kernel stack for secondaries before cpu_restore()") means that it is now possible to use C. Rewrite the functions in C so they are a little bit easier to read. This is not changing their functionality.
