#     powerpc/40x: Make more space for system call exception
#     
#     When CONFIG_VIRT_CPU_ACCOUNTING is selected, system call exception
#     handler doesn't fit below 0xd00 and build fails.
#     
#     As exception 0xd00 doesn't exist and is never generated by 40x,
#     comment it out in order to get more space for system call exception.
#     
#     Fixes: 9e27086292aa ("powerpc/32: Warn and return ENOSYS on syscalls from kernel")
