This reverts commit 4217374611.
It turns out that the kernel passes any unrecognized arguments on to init,
and (at least) N6 and N9 have such arguments. My lazy check of argc was
thus insufficient to recognize what stage of init we were in, so we'd
skip to stage 2 and not set up SELinux. And apparently you can get a
very long way with SELinux off... We'll fix that in a later change.

tzdatacheck is exec'd from init.rc early in boot just after /data is
mounted. It checks to make sure that the tz rule data in /data
is newer than the version in /system. If the data is older it is
deleted. This is to address problems with earlier tz rule updates
that occurred: after an OTA upgrade previous updates in /data
would override newer versions in the system partition.
Includes change to init.rc neccessary to run it at boot time. Other
changes are in external/selinux.

The earliest point we can start logd is after /system is mounted.
Ideally on post-fs-system (does not exist), post-fs will do.
As insurance, we will also make sure logd is started if a
logd-reinit is requested. This results in logd starting at least
4 processes earlier than it does currently, with a tighter
grouping of threads which means we are taking advantage of a
lighter CPU load at the time, rather than taking cycles during
heavy activity during core startup.

Also make important events in init's life NOTICE rather than INFO,
and ensure that NOTICE events actually make it to the kernel log.
Also fix the logging so that if you have a printf format string
error, the compiler now catches it.
Also give messages from init, ueventd, and watchdogd distinct tags.
(Previously they'd all call themselves "init", and dmesg doesn't
include pids, so you couldn't untangle them.)
Also include the tag in SELinux messages.

bootchart uses a file on the data partition to decide if it should collect
data for bootchart, but the data partition will be mounted by the mount_all
command in the "on fs" section, and it will be only added into the action
queue when command "trigger fs" is executed, but that's after the
bootchart_init action (late_init).
This change makes bootchart_init a builtin command of init,
and make it executed as the first command of "on post-fs" section
which will be triggered after the "on fs" section.
This change also refactors the bootchart code to all be in bootchart.cpp.

This reverts commit bda6272446.
The original fix seems to have led to boot failures in QA. Rather than
risk shipping, revert the change. Bug 18764230 reopened.

The upstream kernel now includes support for emulating legacy AArch32
instructions on ARMv8 devices. By default this framework emulates
deprecated instructions but not obsolete instructions.
Android requires support for the obsolete SWP and SWPB instructions on
all ARM devices, so override this default for the swp emulation hook.

on reboot /sys/fs/pstore/pmsg-ramoops-0 provides a means
to pull and triage user-space activities leading
up to a panic. A companion to the pstore console logs.
