#     powerpc/kasan: Fix stack overflow by increasing THREAD_SHIFT
#     
#     When CONFIG_KASAN is selected, the stack usage is increased.
#     
#     In the same way as x86 and arm64 architectures, increase
#     THREAD_SHIFT when CONFIG_KASAN is selected.
#     
#     Fixes: 2edb16efc899 ("powerpc/32: Add KASAN support")
