If NIOS2_CMDLINE_IGNORE_DTB is selected but CMDLINE_BOOL isn't and thus
CONFIG_CMDLINE is not defined, the build fails with the following error:
arch/nios2/kernel/setup.c: In function 'nios2_boot_init':
arch/nios2/kernel/setup.c:131:30: error: 'CONFIG_CMDLINE' undeclared
(first use in this function)
strncpy(boot_command_line, CONFIG_CMDLINE, COMMAND_LINE_SIZE);
This can be reproduced using randconfig with KCONFIG_SEED=0xE5B8749E, i.e.
'make KCONFIG_SEED=0xE5B8749E ARCH=nios2 randconfig'.
Fix this by letting NIOS2_CMDLINE_IGNORE_DTB depend on CMDLINE_BOOL, so we
actually have a default kernel command string to fall back to.

kernel/time/Kconfig expects that NR_CPUS is defined.

Move asm-generic/io.h to end of file to override functions like
phys_to_virt, virt_to_phys in asm-generic/io.h.
This is due to recent commit 9216efaf introduced new way to
override functions by checking for the existence of a macro with the
same of the function.

This patch adds support for system calls from userspaces. It uses the

The sys_call_table is just an array defined in a C file and it contains
