Enable this to be lazy in the saving of the FPU state to the owning

task's thread struct. This is useful if most tasks on the system

don't use the FPU as only those tasks that use it will pass it

between them, and the state needn't be saved for a task that isn't

using it.

This can't be so easily used on SMP as the process that owns the FPU
|
|
state on a CPU may be currently running on another CPU, so for the
|
|
moment, it is disabled.

This enables support for systems with more than one CPU. If you have
|
|
a system with only one CPU, like most personal computers, say N. If
|
|
you have a system with more than one CPU, say Y.
|
|
|
|
If you say N here, the kernel will run on single and multiprocessor
|
|
machines, but will use only one CPU of a multiprocessor machine. If
|
|
you say Y here, the kernel will run on many, but not all,
|
|
singleprocessor machines. On a singleprocessor machine, the kernel
|
|
will run faster if you say N here.

This option removes the E2/R2 register from the set available to gcc
|
|
for normal use and instead uses it to store the address of the

|
current process's task_struct whilst in the kernel.
|
|
|
|
This means the kernel doesn't need to calculate the address each time
|
|
"current" is used (take SP, AND with mask and dereference pointer
|
|
just to get the address), and instead can just use E2+offset
|
|
addressing each time.

local_irq_disable() doesn't actually disable maskable interrupts -
|
|
what it does is restrict the levels of interrupt which are permitted
|
|
(a lower level indicates a higher priority) by lowering the value in
|
|
EPSW.IM from 7. Any interrupt is permitted for which the level is
|
|
lower than EPSW.IM.
|

Certain interrupts, such as DEBUGGER and virtual MN10300 on-chip
|
|
serial DMA interrupts are allowed to interrupt normal disabled
|

sections.
