Before calling into the filesystem, vfs_setxattr calls
security_inode_setxattr, which ends up calling selinux_inode_setxattr in
our case. That returns -EOPNOTSUPP whenever SBLABEL_MNT is not set.
SBLABEL_MNT was supposed to be set by sb_finish_set_opts, which sets it
only if selinux_is_sblabel_mnt returns true.
The selinux_is_sblabel_mnt logic was broken by eadcabc697 "SELinux: do
all flags twiddling in one place", which didn't take into the account
the SECURITY_FS_USE_NATIVE behavior that had been introduced for nfs
with eb9ae68650 "SELinux: Add new labeling type native labels".
This caused setxattr's of security labels over NFSv4.2 to fail.

Instead of hard wiring the WCLK frequency at probe time do it runtime.
The hard wired 88_96KHz was not even setting the correct bits since it was
defined as (1 << 6) which will change the I2S_OUT_SEL bit and will leave
the amplifier configured for 8KHz.
At the same time clean up and fix the CFG3 register bits.

The following patch adds coupled cpuidle support for Exynos3250 to
an existing cpuidle-exynos driver. As a result it enables AFTR mode
to be used by default on Exynos3250 without the need to hot unplug
CPU1 first.
The detailed changelog:
- use exynos_[get,set]_boot_addr() in cpuidle-exynos.c and then make
cpu_boot_reg_base() static
- use exynos_core_restart() in exynos_cpu0_enter_aftr()
- add missing smp_rmb() to exynos_cpu0_enter_aftr() (to make the code
in-sync with the platform SMP code)
- add call_firmware_op(cpu_boot, 1) to exynos_cpu0_enter_aftr()
- use dsb_sev() instead of IPI wakeup for Exynos3250 in
exynos_cpu0_enter_aftr()
- add CPU0 vs CPU1 synchronization based on S5P_PMU_SPARE2 register
for Exynos3250 to cpuidle-exynos.c
- add flush_cache_all() for CPU1/0 before powerdown/AFTR for
Exynos3250 to exynos_wfi_finisher()/exynos_do_idle()

Using a fixed (by DTS) parent for clocks when turning on the power
domain may introduce issues in other drivers. For example when such
driver changes the parent during runtime and expects that he is the
only place of such change.
Do not rely on DTS providing the fixed parent for such clocks. Instead
before switching domain off, grab a current parent of a clock with
clk_get_parent().
