When kernel debugger support is requested ipc and vm need
the prototype for the debugger function kdbprintf.

By disabling some of the most slow drivers by default, and giving progress
feedback to the user.

`allowed_drive_mask' floppy drives whose cmos type is 0.

0a55db5 made thread_suspend return KERN_FAILURE when the target thread is in
TH_UNINT state. That however is not currently handled by libc, and it's more
useful to just wait for the thread to get interruptible.
* kern/sched_prim.c (thread_invoke): Wake NEW_THREAD->STATE for thread_suspend.
* kern/thread.c (thread_suspend): Wait on NEW_THREAD->STATE as long as THREAD
has TH_UNINT.

Based upon a patch by Philippe De Muyter, and feedback from Mark
Lord and Robert Hancock.
As noted by Mark Lord, the outdated ATA1 spec specifies a 20msec
timeout for setting DRQ but lots of common devices overshoot this.

Some versions of GCC will error if you define a type twice (even if
the definition is the same). The NCR53C8XX SCSI driver defines
'vm_offset_t', this is also defined in vm_types.h and will therefore
cause a compilation error depending on the GCC version.
* linux/src/drivers/scsi/ncr53c8xx.c [!MACH] (vm_offset_t, vm_size_t): Don't
define types.

stack allocation.

destination map tree.

and the implementation doesn't make all of them clearly appear. Remove
cases numbering references to avoid confusion.

Grub is not able to map us at high addresses. We can however make it load us at
low addresses (through the linker script mapping), then use segmentation to move
ourselves to high addresses, and switch to C which uses high addresses
(through _START definition).

0xffffffff.

When _start is not close to 0, just using init_alloc_aligned() is not enough
to know how much should be duplicated between linear and virtual mappings.
Just mapping everything that can be is not very costly and should just work
when it can work.
* i386/i386at/model_dep.c (i386at_init) [VM_MIN_KERNEL_ADDRESS !=
LINEAR_MIN_KERNEL_ADDRESS]: Extend `nb_direct' to VM_MIN_KERNEL_ADDRESS -
LINEAR_MIN_KERNEL_ADDRESS.
