Linus Torvalds c013632192 2nd set of arm64 updates for 4.16: ... Spectre v1 mitigation: - back-end version of array_index_mask_nospec() - masking of the syscall number to restrict speculation through the syscall table - masking of __user pointers prior to deference in uaccess routines Spectre v2 mitigation update: - using the new firmware SMC calling convention specification update - removing the current PSCI GET_VERSION firmware call mitigation as vendors are deploying new SMCCC-capable firmware - additional branch predictor hardening for synchronous exceptions and interrupts while in user mode Meltdown v3 mitigation update for Cavium Thunder X: unaffected but hardware erratum gets in the way. The kernel now starts with the page tables mapped as global and switches to non-global if kpti needs to be enabled. Other: - Theoretical trylock bug fixed -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAlp8lqcACgkQa9axLQDI XvH2lxAAnsYqthpGQ11MtDJB+/UiBAFkg9QWPDkwrBDvNhgpll+J0VQuCN1QJ2GX qQ8rkv8uV+y4Fqr8hORGJy5At+0aI63ZCJ72RGkZTzJAtbFbFGIDHP7RhAEIGJBS Lk9kDZ7k39wLEx30UXIFYTTVzyHar397TdI7vkTcngiTzZ8MdFATfN/hiKO906q3 14pYnU9Um4aHUdcJ+FocL3dxvdgniuuMBWoNiYXyOCZXjmbQOnDNU2UrICroV8lS mB+IHNEhX1Gl35QzNBtC0ET+aySfHBMJmM5oln+uVUljIGx6En1WLj6mrHYcx8U2 rIBm5qO/X/4iuzYPGkxwQtpjq3wPYxsSUnMdKJrsUZqAfy2QeIhFx6XUtJsZPB2J /lgls5xSXMOS7oiOQtmVjcDLBURDmYXGwljXR4n4jLm4CT1V9qSLcKHu1gdFU9Mq VuMUdPOnQub1vqKndi154IoYDTo21jAib2ktbcxpJfSJnDYoit4Gtnv7eWY+M3Pd Toaxi8htM2HSRwbvslHYGW8ZcVpI79Jit+ti7CsFg7m9Lvgs0zxcnNui4uPYDymT jh2JYxuirIJbX9aGGhnmkNhq9REaeZJg9LA2JM8S77FCHN3bnlSdaG6wy899J6EI lK4anCuPQKKKhUia/dc1MeKwrmmC18EfPyGUkOzywg/jGwGCmZM= =Y0TT -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull more arm64 updates from Catalin Marinas: "As I mentioned in the last pull request, there's a second batch of security updates for arm64 with mitigations for Spectre/v1 and an improved one for Spectre/v2 (via a newly defined firmware interface API).
