"Allows hard booting (i.e., with a full hardware reboot) to a kernel
previously loaded in memory by kexec.  This works around the problem of
soft-booted kernel hangs due to improper device shutdown and/or
reinitialization."

This reverts commit 87576b8.

The min/max call needed to have explicit types on some architectures
(e.g. mn10300). Use clamp_t instead to avoid the warning:

  kernel/sys.c: In function 'override_release':
  kernel/sys.c:1287:10: warning: comparison of distinct pointer types lacks a cast [enabled by default]

Calling uname() with the UNAME26 personality set allows a leak of kernel
stack contents.  This fixes it by defensively calculating the length of
copy_to_user() call, making the len argument unsigned, and initializing
the stack buffer to zero (now technically unneeded, but hey, overkill).

"echo -e" is a GNU extension. When cross-compiling the kernel on a
BSD-like operating system (Mac OS X in my case), this doesn't work.

One could install a GNU version of echo, put that in the $PATH before
the system echo and use "/usr/bin/env echo", but the solution with
printf is simpler.

Since it is no disadvantage on Linux, I hope that gets accepted even if
cross-compiling the Linux kernel on another Unix operating system is
quite a rare use case.

When interval time is too short between al3101_early_suspend() and al3010_late_resume().
It will cause driver fail to set power on. So , add 5ms delay to fix this issue.

Revise the equation of compass compensation to
make the data moving curve more linear when rotating.
This fixes that the Orientation data variation doesn't match the degrees
that the device actually has been rotated.

Remove all audio routing and use two switch devices
to signal userspace of dock changes. Routing can
then be done in userspace for the dock.

To load compass gain with a correct type, we should fix it to 'int'.
This should be common fix but partial related to bug 7355959.

…oving headset rapidly.

Speaker could get silent if insert and remove headphone rapidly,
or even just normally insert and remove headphone during system suspend.

The "AUX" and "speaker" dapm mixer control was for dock function but causes such issue,
now remove them from kernel and redesign in HAL to satisfy both audio and dock functions.

Since BlueDroid does not use kernel space HCI driver now, we add the
below 2 /proc nodes to make BlueDroid able to send HCI events to
bluesleep driver.
