[tip: efi/urgent] efi: stub: omit SetVirtualAddressMap() if marked unsupported in RT_PROP table

This mostly does not concern the EFI stub at all, given that it runs before that. However, there is one call that is made at runtime, which is the call to SetVirtualAddressMap() (which is not even callable at boot time to begin with) So add the missing handling of the RT_PROP table to ensure that we only call SetVirtualAddressMap() if it is not being advertised as unsupported by the firmware.

[PATCH] crypto: mips/poly1305 - enable for all MIPS processors

by Maciej W. Rozycki

The MIPS Poly1305 implementation is generic MIPS code written such as to support down to the original MIPS I and MIPS III ISA for the 32-bit and 64-bit variant respectively. Lift the current limitation then to enable code for MIPSr1 ISA or newer processors only and have it available for all MIPS processors. Signed-off-by: Maciej W. Rozycki <macro(a)orcam.me.uk> Fixes: a11d055e7a64 ("crypto: mips/poly1305 - incorporate OpenSSL/CRYPTOGAMS optimized implementation") Cc: stable(a)vger.kernel.org # v5.5+ --- On Wed, 3 Mar 2021, Jason A.

The performance boost on Octeon is significant for WireGuard users. But that's the wrong fix for that purpose. I've skimmed over that module and there's nothing MIPS64-specific there. In fact it's plain generic MIPS assembly, with some R2 optimisations enabled where applicable but not necessary (and then R6 tweaks, but that's irrelevant here). As a matter of interest I have just built it successfully for a MIPS I DECstation configuration: $ file arch/mips/crypto/poly1305-mips.ko arch/mips/crypto/poly1305-mips.ko: ELF 32-bit LSB relocatable, MIPS, MIPS-I version 1 (SYSV), BuildID[sha1]=d36384d94f60ba7deff638ca8a24500120b45b56, not stripped $ Patch included, please apply. So while your change is surely right, what you want is this really.
