balloon: try harder to balloon up under memory pressure.

Currently if the balloon driver is unable to increase the guest's
reservation it assumes the failure was due to reaching its full
allocation, gives up on the ballooning operation and records the limit
it reached as the "hard limit". The driver will not try again until
the target is set again (even to the same value).

However it is possible that ballooning has in fact failed due to
memory pressure in the host and therefore it is desirable to keep
attempting to reach the target in case memory becomes available. The
most likely scenario is that some guests are ballooning down while
others are ballooning up and therefore there is temporary memory
pressure while things stabilise. You would not expect a well behaved
toolstack to ask a domain to balloon to more than its allocation nor
would you expect it to deliberately over-commit memory by setting
balloon targets which exceed the total host memory.

This patch drops the concept of a hard limit and causes the balloon
driver to retry increasing the reservation on a timer in the same
manner as when decreasing the reservation.

Also if we partially succeed in increasing the reservation
(i.e. receive less pages than we asked for) then we may as well keep
those pages rather than returning them to Xen.

476 There are two different types of booting firmware on Alphas: SRM,

479 the Linux/Alpha FAQ, accessible on the WWW from
480 <http://www.alphalinux.org/>.
482 The usual way to load Linux on an Alpha machine is to use MILO
483 (a bootloader that lets you pass command line parameters to the
484 kernel just like lilo does for the x86 architecture) which can be
485 loaded either from ARC or can be installed directly as a permanent
486 firmware replacement from floppy (which requires changing a certain
487 jumper on the motherboard). If you want to do either of these, say N
488 here. If MILO doesn't work on your system (true for Jensen
489 motherboards), you can bypass it altogether and boot Linux directly
490 from an SRM console; say Y here in order to do that. Note that you
491 won't be able to boot from an IDE disk using SRM.

584 machine checks, but wanted the default to be as if verbose
585 machine check printing was turned off, then one would choose
586 the printing mode to be 0. Then, upon reboot, one could add
587 the boot command line "verbose_mcheck=1" to get the normal
588 verbose machine check printing, or "verbose_mcheck=2" to get
589 the maximum information available.
591 Take the default (1) unless you want more control or more info.

601 ---help---
602 If you enable this option, a subdirectory inside /proc called
603 /proc/srm_environment will give you access to the all important
604 SRM environment variables (those which have a name) and also
605 to all others (by their internal number).
607 SRM is something like a BIOS for Alpha machines. There are some
608 other such BIOSes, like AlphaBIOS, which this driver cannot
609 support (hey, that's not SRM!).
611 Despite the fact that this driver doesn't work on all Alphas (but
612 only on those which have SRM as their firmware), it's save to
613 build it even if your particular machine doesn't know about SRM
614 (or if you intend to compile a generic kernel). It will simply
615 not create those subdirectory in /proc (and give you some warning,
616 of course).
618 This driver is also available as a module and will be called
619 srm_env then.
