Limit number of accumulated non-balloonable pages during inflation cycle,
otherwise there is a chance we will be spinning and growing the list
forever. This happens during torture tests when balloon target changes
while we are in the middle of inflation cycle and monitor starts refusing
to lock pages (since they are not needed anymore).

As explained in commit 1c0fe6e3bd ("mm: invoke oom-killer from page
fault") , we want to call the architecture independent oom killer when
getting an unexplained OOM from handle_mm_fault, rather than simply
killing current.

The driver fails to compile on s390:
drivers/char/ramoops.c: In function 'ramoops_init':
drivers/char/ramoops.c:122: error: implicit declaration of function 'ioremap'
Since we won't make use of the driver anyway on s390 just let it depend on
HAS_IOMEM.

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6:
ACPI: Eliminate us to pm ticks conversion in common path
ACPI: Fix the incorrect calculation about C-state idle time
ACPI: update feature-removal.txt to reflect deleted acpi=ht option
ACPI / EC / PM: Fix names of functions that block/unblock EC transactions
ACPI / EC / PM: Fix race between EC transactions and system suspend
acpi_enter_[simple|bm] routines does us to pm tick conversion on every
idle wakeup and the value is only used in /proc/acpi display. We can
store the time in us and convert it into pm ticks before printing instead and
avoid the conversion in the common path.

The C-state idle time is not calculated correctly, which will return the wrong
residency time in C-state. It will have the following effects:
1. The system can't choose the deeper C-state when it is idle next time.
Of course the system power is increased. E.g. On one server machine about 40W
idle power is increased.
2. The powertop shows that it will stay in C0 running state about 95% time
although the system is idle at most time.
