Merge change from amd64 machdep.c revision 1.42:
in cpu_reboot(), only halt the other CPUs after we've done the powerdown stuff.
the ACPI code may end up removing some pmap entries, which wants the other
CPUs to still be running to handle TLB invalidations.
PR# kern/37506: Have to hold power button for 5 seconds to turn off Laptop
after "halt" command.
Transfer the system from ACPI to Legacy mode if RB_HALT is set.
Also do the missed rename of multiboot_ksyms_init to
multiboot_ksyms_addsyms_elf to compile with MULTIBOOT set.
This caused a minor and a more serious bug in the past:
- dmesg did not contain the information about the loader
- /dev/ksyms did not work when the kernel was booted with a
multiboot bootloader (grub for example)

and amd64 where VESA VBE 2.0+ is available.
* Add helper library and stubs to invoke VBE bioscalls.
* Bump HEAP_START as we were already dangerously close to our limits.
* bootdataseg now allows access > 16MB so in the future we can scribble
on the framebuffer.
* Pass BTINFO_FRAMEBUFFER parameters to kernel when configured.
* VBE modes are configured with the new 'vesa' command. Usage, when present:
* vesa {enabled|disabled}
Enable / disable linear framebuffer, default mode is 640x480x8. May
be changed in the future to determine mode based on VBE/DDC where
available.
* vesa list
List modes supported by the firmware that meet the following criteria:
* linear framebuffer
* packed pixel or direct colour mode
* vesa {modenum|modestr}
Enable specific VBE mode. The mode can be specified either as a
VBE mode number (eg. 0x101) or as a string (eg. 800x600x16).
option MODULAR to using %MODULAR%. While it is now possible to only
request the new version in the affected Makefiles, it is made mandatory for
everybody because I just fixed a bug in config(1) that would not make it
fail in the case of a syntax error in the Makefile template.
generated by config(1) in the kernel compile directory no longer
contains IDENT=-DMODULAR. Instead, there's an opt_modular.h file that
might or might not contain "#define MODULAR 1".
Adapt to this by adding an OPT_MODULAR variable to relevant Makefiles,
set via an awk script that parses opt_modular.h.
call x86_bus_space_init() and x86_bus_space_mallocok() if we have ISA or PCI
devices configured; not only for non-Xen or dom0 Xen
On Xen, always call PHYSDEVOP_SET_IOPL on context switch
on amd64, also call PHYSDEVOP_SET_IOPL from x86_64_proc0_tss_ldt_init()
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)

to avoid unnecessary 64 bit ops which would make binaries larger:
satime_t (currently unsigned int):
numbers in seconds returned by the machine dependent getsecs() function
which are used to measure relative time
saseconds_t (currently int):
numbers in seconds used to specify timeout to network drivers
Per discussion on current-users.
* Add missing close brace in do { ... } while(0)
* The return value from snprintb is an int and not usable with printf
"%s" format; print the result buffer instead.
