When I see recent change of swap readahead, I am very unhappy
about current code structure which diverges two swap readahead
algorithm in do_swap_page. This patch is to clean it up.
Main motivation is that fault handler doesn't need to be aware of
readahead algorithms but just should call swapin_r
This patch makes do_swap_page no need to be aware of two different
swap readahead algorithm. Just unify cluster-based and vma-based
readahead function call.

I found that on kernel linux3.10, 64-bit, not virtual machine, when I
attach my process to a newly created cgroup
(/sys/fs/cgroup/cpu,cpuacct/p1), the cputime collection of
cpuacct.stat and cpuacct.usage have a big difference. Cputime in
cpuacct.stat is too much bigger than cpuacct.usage.

Banana Pi M2 Zero board is a H2+-based board by Sinovoip, with a form
factor and GPIO holes similar to Raspberry Pi Zero.
It features:
- Allwinner H2+ SoC
- Single-chip (16-bit) 512MiB DDR3 DRAM
- Ampak AP6212 Wi-Fi/Bluetooth module
- MicroSD slot
- Two MicroUSB Type-B ports (one can only be used

Variable trip is assigned but never read, hence it is redundant
and can be removed. Cleans up clang warning:

After commit 9e8e865bbe29 ("arm64: unify idmap removal"), we no need to
flush tlb in suspend.c, so the included file tlbflush.h can be removed.
