[PATCH 0/1] MR6128: ntdll: Map PSTATE.SS to the x86 trap flag on ARM64EC.

[Billy Laws (＠bylaws)]

Tested with my FEX windows port by setting cpsr bits before rethrowing an exception and observing the resulting eflags in an x86 program with an exception filter. There are no additional mappings (though this could be extended using reserved bits to pass through pf/af)
