Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled and we even check
and yell when an interrupt handler returns with interrupts enabled (see
commit [b738a50a: genirq: Warn when handler enables interrupts]).So now this flag is a NOOP and can be removed.

Loongson builds have an ad-hoc cmdline default of "console=ttyS0,115200
root=/dev/hda1". These settings come from a vendor; I remember builds
from Lemote branch requiring a "console=tty" override in order to get a
working console.At least on Yeeloong, they're particularly useless: there's no external
serial port, and the IDE drive is now recognised as /dev/sda.Signed-off-by: Robert Millan

While at it, fix two checkpatch errors.
Several non-const struct instances constified by this patch were added after
the introduction of platform_suspend_ops in checkpatch.pl's list of "should
be const" structs (79404849e90a41ea2109bd0e2f7c7164b0c4ce73).Patch against mainline.

The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed
the out-of-order issue of Loongson-2F described in chapter 15 of the
Loongson2F User Manual [1, 2], but introduced some problems.The option changes all of the jump target to "addr & 0xcfffffff" through the
at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is
wrong. Avoids the problem via telling the assembler to not use the $at
register.[1] Loongson2F User Manual (Chinese Version)

In the old source code, I have let halt and poweroff do the same action,
but in reality, they have different meanings.As the manpage of shutdown shows:
-r Reboot after shutdown.
-H Halt action is to halt or drop into boot monitor on systems that support it.
-P Halt action is to turn off the power.and in the real world, some machines(e.g. NAS) did not provide a power
button and the shutdown works as reset, so, we need to provide a
mechanism to let the users turn off the power safely without breaking
the system, such a mechanism is "halt", which only put the system into a
dead loop or a power-save mode and print some information to the screen
to tell the users to turn off the power safely.$ shutdown -hH now /* loongson_halt, not turn off the power */
$ shutdown -hP now /* loongson_poweroff, work as poweroff */Signed-off-by: Wu Zhangjin
