kexec: dont initialise regions in reserve_memory()

There is no need to initialise efi_memmap_res and boot_param_res in
reserve_memory() for the initial xen domain as it is done in
machine_kexec_setup_resources() using values from the kexec hypercall.

46 The Extended Industry Standard Architecture (EISA) bus was
47 developed as an open alternative to the IBM MicroChannel bus.
49 The EISA bus provided some of the features of the IBM MicroChannel
50 bus while maintaining backward compatibility with cards made for
51 the older ISA bus. The EISA bus saw limited use between 1988 and
52 1995 when it was made obsolete by the PCI bus.

71 modems or hard drives often used with laptops computers. There are
72 actually two varieties of these cards: the older 16 bit PCMCIA cards
73 and the newer 32 bit CardBus cards. If you want to use CardBus
74 cards, you need to say Y here and also to "CardBus support" below.
76 To use your PC-cards, you will need supporting software from David

295 bool "Math emulation extra precision"

297 help
298 The fpu uses normally a few bit more during calculations for
299 correct rounding, the emulator can (often) do the same but this
300 extra calculation can cost quite some time, so you can disable
301 it here. The emulator will then "only" calculate with a 64 bit
302 mantissa and round slightly incorrect, what is more then enough
303 for normal usage.

306 bool "Math emulation only kernel"

308 help
309 This option prevents any floating-point instructions from being
310 compiled into the kernel, thereby the kernel doesn't save any
311 floating point context anymore during task switches, so this
312 kernel will only be usable on machines without a floating-point
313 math coprocessor. This makes the kernel a bit faster as no tests
314 needs to be executed whether a floating-point instruction in the
315 kernel should be executed or not.

322 it possible for you to improve performance somewhat if you know what
323 you are doing.

327 the questions about these options.

335 This allows to use certain instructions that work with indivisible
336 read-modify-write bus cycles. While this is faster than the
337 workaround of disabling interrupts, it can conflict with DMA
338 ( = direct memory access) on many Amiga systems, and it is also said
339 to destabilize other machines. It is very likely that this will
340 cause serious problems on any Amiga or Atari Medusa if set. The only
341 configuration where it should work are 68030-based Ataris, where it
342 apparently improves performance. But you've been warned! Unless you
343 really know what you are doing, say N. Try Y only if you're quite
344 adventurous.

355 bool "Use write-through caching for 68060 supervisor accesses"
356 depends on ADVANCED && M68060
357 ---help---
358 The 68060 generally uses copyback caching of recently accessed data.
359 Copyback caching means that memory writes will be held in an on-chip
360 cache and only written back to memory some time later. Saying Y
361 here will force supervisor (kernel) accesses to use writethrough
362 caching. Writethrough caching means that data is written to memory
363 straight away, so that cache and memory data always agree.
364 Writethrough caching is less efficient, but is needed for some
365 drivers on 68060 based systems where the 68060 bus snooping signal
366 is hardwired on. The 53c710 SCSI driver is known to suffer from
367 this problem.

639 (/dev/tty0) will still be used as the system console by default, but
640 you can alter that using a kernel command line option such as
641 "console=ttyS1". (Try "man bootparam" or see the documentation of
642 your boot loader (lilo or loadlin) about how to pass options to the
643 kernel at boot time.)
645 If you don't have a VGA card installed and you say Y here, the
646 kernel will automatically use the first serial line, /dev/ttyS0, as
647 system console.
649 If unsure, say N.
