Justin Hibbits 161c415133 Two fixups for dtrace ... * Use the right incantation to get the next stack pointer. Since powerpc uses special frames for traps, dereferencing the stack pointer straight up won't get us the next stack pointer in every case. * Clear EE using the correct instruction sequence. The PowerISA states that 'andi.' ANDs the register with 0||<imm>, instead of sign extending or filling out the unavailable bits with 1. Even if it did sign extend, PSL_EE is 0x8000, so ~PSL_EE is 0x7fff, and the upper bits would be cleared. Use rlwinm in the 32-bit case, and a two-rotate sequence in the 64-bit case, the latter chosen to follow the output generated by gcc. MFC after: 1 week		2016-08-06 15:06:19 +00:00
