+ security= [SECURITY] Choose a security module to enable at boot.

[SECURITY] Disable capabilities. This would normally
be used only if an alternative security model is to be

idebus= [HW] (E)IDE subsystem - VLB/PCI bus speed
than 32 bit addressing. The default is to look
for translation below 32 bit and if not available
then look in the higher range.
+ strict [Default Off]
+ With this option on every unmap_single operation will

io_delay= [X86-32,X86-64] I/O delay method

kstack=N [X86-32,X86-64] Print N words from the kernel stack

nr_uarts= [SERIAL] maximum number of UARTs to be registered.
+ olpc_ec_timeout= [OLPC] ms delay when issuing EC commands
+ Rather than timing out after 20 ms if an EC

routing table. These calls are known to be buggy
on several machines and they hang the machine
