powerpc/64e/interrupt: Fix nvgprs being clobbered # # Some interrupt handlers have an "extra" that saves 1 or 2 # registers (r14, r15) in the paca save area and makes them available to # use by the handler. # # The change to always save nvgprs in exception handlers lead to some # interrupt handlers saving those scratch r14 / r15 registers into the # interrupt frame's GPR saves, which get restored on interrupt exit. # # Fix this by always reloading those scratch registers from paca before # the EXCEPTION_COMMON that saves nvgprs. # # Fixes: 4228b2c3d20e ("powerpc/64e/interrupt: always save nvgprs on interrupt") # Reported-by: Christian Zigotzky # Signed-off-by: Nicholas Piggin # Tested-by: Christian Zigotzky # Signed-off-by: Michael Ellerman # Link:
