Subject: [PATCH] crypto: mips/poly1305 - enable for all MIPS processors
|
||
|
|
|
||
|
|
commit 6c810cf20feef0d4338e9b424ab7f2644a8b353e upstream.
|
||
|
|
|
||
|
|
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.
