Rather than #define the options manually in the architecture code, add Kconfig options for them and select them there instead. This also allows us to select the compat IPC version parsing automatically for platforms using the old compat IPC interface.

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

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.
