[PATCH] powerpc/ppc-opcode: Fix PPC_RAW_TW()
From: Christophe Leroy <hidden>
Date: 2022-08-03 11:48:03
Also in:
lkml
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
PPC_RAW_TW() is erroneously defined with base code 0x7f000008
instead of 0x7c000008.
That's invisible because its only user is PPC_RAW_TRAP() which is
0x7fe00008, but fix it anyway to avoid any risk of future bug.
