from accessing cpu_data too early, i.e. before smp_store_cpu_info() has copied the boot_cpu_data ontop and overwritten an already empty structure (which we shouldn't access that early in the first place anyway). The second patch is kinda largish for that late in the game but it shouldn't be problematic because we're simply switching from using cpu_data to use the CPU family number directly and thus again, not use uninitialized cpu_data structure. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJSCT0UAAoJEBLB8Bhh3lVKWNsQAJbu1y79mc2vHR15NqMGXVoP F6sUNC3iUnNjxlUxWn3PPynsJS9zFTBEo1S6ILnsfuMWliDoH+4psHLMmG5F20TV XJCSS9s3fdsaJZiNa7JXggdI80xU3y8uB/z3nacRDKgcdw3tX+ITP4SdPgNF5F3k B/XGAFxyXfl9M9SRFMIO4GS9UyFMsDQP0VWMRhcosY1/Fj5bc9Uds1ngP9E4XMe9 jB1pIzbvtDvtolYSdShwFE9M0os90TYPHVSgriYYXHLZPryZC8mWkc7GwSTl4bG9 EwBGXv79SJWics9vWM2n9EQbFt46fUAyhpjyOo/fqVp4L5XjKuV7UyeT7X+bsY0q b3z1jWzBxGZ5ltE2BmZ8tVnfKgwYJlKgAf8FbSrylhtBInP80Wau1aYTzw50h9D2 lmjO/rSOhm2FszdeFHG/IeVbSZJbSFrUdwm51nx2xF1qG0MXldy9ehJ4pO3Ui2XA d0z2y83ZxOYV723fTCa1/5C5xAes7LjvxftM32G9QTu7R5XnvVrfehVfPh9K1DJA nIEH6pbM358/PT+/q7BCPTnH7KVi+mE633YERDOfAgz/NFnVKfKzLBM0+AyFNHjk a4xFrOqVbTctW1Chv8Nh1457A2+gcT8yeju1XjbLE8IMqKOGyMt0gnRZlgMYj8BH WYKWi2q0LaDwsOcaQ9bm =cxbY -----END PGP SIGNATURE----- Merge tag 'amd_ucode_fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp into x86/urgent Pull AMD microcode fixes from Borislav Petkov: " Those are basically two fixes which correct the AMD early ucode loader from accessing cpu_data too early, i.e. before smp_store_cpu_info() has copied the boot_cpu_data ontop and overwritten an already empty structure (which we shouldn't access that early in the first place anyway).
