#     powerpc/kasan: Disable KCOV in KASAN code
#     
#     As per the generic KASAN code in mm/kasan, disable KCOV with
#     KCOV_INSTRUMENT := n in the makefile.
#     
#     This fixes a ppc64 boot hang when KCOV and KASAN are enabled.
#     kasan_early_init() gets called before a PACA is initialised, but the
#     KCOV hook expects a valid PACA.
