conjunction with KVM_SET_CLOCK, it is used to ensure monotonicity on scenarios
such as migration.
When KVM_CAP_ADJUST_CLOCK is passed to KVM_CHECK_EXTENSION, it returns the
set of bits that KVM can return in struct kvm_clock_data's flag member.
The only flag defined now is KVM_CLOCK_TSC_STABLE. If set, the returned
value is the exact kvmclock value seen by all VCPUs at the instant
when KVM_GET_CLOCK was called. If clear, the returned value is simply
CLOCK_MONOTONIC plus a constant offset; the offset can be modified
with KVM_SET_CLOCK. KVM will try to make all VCPUs follow this clock,
but the exact value read by each VCPU could differ, because the host
TSC is not stable.

help
The kernel memory allocator divides physically contiguous memory
blocks into "zones", where each zone is a power of two number of
pages. This option selects the largest power of two that the kernel
keeps in the memory allocator. If you need to allocate very large
blocks of physically contiguous memory, then you may need to
increase this value.
This config option is actually maximum order plus one. For example,
a value of 13 means that the largest free memory block is 2^12 pages.
