arm64: big-endian: don't treat code as data when copying sigret code

2017-12-14T16:04:49+00:00

Currently the sigreturn compat code is copied to an offset in the vectors table. When using a BE kernel this data will be stored in the wrong endianess so when returning from a signal on a 32-bit BE system, arbitrary code will be executed. Instead of declaring the code inside a struct and copying that, use the assembler's .byte directives to store the code in the correct endianess regardless of platform endianess.
