function.

Andrew Boie f0a1d22f28 x86: leave the GDT in ROM by default
We don't normally need a runtime-mutable GDT; make it optional to
activate a second copy in RAM. Regardless of whether it is in RAM
or ROM, it can be accessed by the '_gdt' symbol.

Andrew Boie 2ee9aca31a irq: size _irq_to_interrupt_vector_table
Most systems have far less than 256 IRQ lines available, so
save some bytes in ROM by making this a config option.

On systems with MVIC, omit the table entirely as the mapping
is fixed.

The build cmd_gen_idt is slightly easier to read and will fail
immediately if any of the commands in the sequence error out.

This option is not building and currently not supported, removing
it because there does not seem to be a use case for it.

Peter Mitsis 4ebdf7f84b Rename NO_NESTED_INTERRUPTS to NESTED_INTERRUPTS
Renames the Kconfig option NO_NESTED_INTERRUPTS to NESTED_INTERRUPTS
as it is typically easier to follow positive logic than it is to
follow negative logic.

Andrew Boie be3e3b0f8c x86: Improve exception/trap debugging
Currently when an unhandled exception or trap occurs, we don't know
specifically which one happened. The CONFIG_EXCEPTION_DEBUG option
installs handlers for various exceptions and prints out details
when they happen.

There is no need for any x86 Kconfig to have a dependency upon the following
Kconfig options as they are always true when building for ARCH=x86.
    X86_32
    ISA_IA32
    ARCH="x86"

Peter Mitsis 87de8c493f x86: Re-order x86 Kconfig menus
The top-level menus "x86 Core Options" and "Bus Options (PCI etc.)" are now
sub-menus to the the top-level menu "General Platform Configurations".

Also, the "Board Capabilities" sub-menu has been hoisted out of the
"x86 Core Options" menu and placed as a renamed sub-menu
(Platform Capabilities) to the top-level "General Platform Configurations"
menu.

This helps to create a more logical flow when using "make menuconfig".
