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") # Reported-by: kbuild test robot # Signed-off-by: Christophe Leroy # Signed-off-by: Michael Ellerman # Link:
