It is theoretically possible for a request to finish and be freed between
writing it to the I/O thread and updating the sector count.  In this case, the
update will dereference a freed pointer.

To avoid this, I delay the update until processing the next sg segment, when
the request pointer is known to be good.

Fix the following section mismatch warnings:
WARNING: arch/alpha/kernel/built-in.o(.text+0x7c78): Section mismatch: reference to .init.text:init_rtc_irq (between 'common_init_rtc' and 'timer_interrupt')
WARNING: arch/alpha/kernel/built-in.o(.text+0x7c7c): Section mismatch: reference to .init.text:init_rtc_irq (between 'common_init_rtc' and 'timer_interrupt')
WARNING: arch/alpha/kernel/built-in.o(.data+0x2c30): Section mismatch: reference to .init.text:srm_console_setup (between 'srmcons' and 'tsunami_pci_ops')

In all three cases functions marked __init was called outside __init context.
So the fix was to just drop the __init attribute.

Be (self-)consistent and use CONFIG_GDB_CONSOLE everywhere rather than using

consistent with other archs.

Also remove the gdbstub console device() op which doesn't seem to be necessary

Beacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and
include/asm-x86_64/serial.h.  the serial8250_ports need to be probed late in
serial initializing stage.  the console_init=>serial8250_console_init=>
register_console=>serial8250_console_setup will return -ENDEV, and console
ttyS0 can not be enabled at that time.  need to wait till uart_add_one_port in
drivers/serial/serial_core.c to call register_console to get console ttyS0.
that is too late.

Make early_uart to use early_param, so uart console can be used earlier.  Make
it to be bootconsole with CON_BOOT flag, so can use console handover feature.
and it will switch to corresponding normal serial console automatically.

new command line will be:
	console=uart8250,io,0x3f8,9600n8
	console=uart8250,mmio,0xff5e0000,115200n8
or
	earlycon=uart8250,io,0x3f8,9600n8
	earlycon=uart8250,mmio,0xff5e0000,115200n8

it will print in very early stage:
	Early serial console at I/O port 0x3f8 (options '9600n8')
	console [uart0] enabled
later for console it will print:
	console handover: boot [uart0] -> real [ttyS0]

On some motherboards ACPI C3 is available, but it isn't
causing frequency transition on VIA Nehemiah. Longhaul
wasn't working at all earlier, but due to
scaling_cur_speed returning true CPU frequency now, it
looks like CPU is getting stuck at highest frequency
since 2.6.21. I didn't find a reason. Halt is causing
