#     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")
