[PATCH 0/1] MR572: ntdll: Use correct mcontext struct on macOS under Wow64.

[Brendan Shanks (＠bshanks)]

This bug was causing incorrect FPU state to be read under Wow64 on macOS.

This use of different mcontext structures is only documented in Apple's kernel source, most helpfully a test program for custom LDTs: https://github.com/apple-oss-distributions/xnu/blob/e7776783b89a353188416a9a...
