intel_pstate sysfs should not co-exist when acpi-cpufreq is also present.
Fix this issue by deleting the intel_pstate sysfs if the driver failed
to be loaded during bootup.

Hi Masami,
Thanks for writing bootconfig and it is useful for boot up trace event
debugging.
However it was found that on 5.10-rc2 the bootconfig does not work and it shows
"'bootconfig' found on command line, but no bootconfig found"
And the reason for this is the kernel found the magic number to
(), except that the former returns the result
of this reset.
No functional change expected.

in [1/2 patch], it might exit the s2idle phase directly once when we see
TIF_NEED_RESCHED is set(because entered_state is postive we treat it as a
successful

Currently the WOL(Wake On Lan) bahavior of e1000e is not consistent with its
corresponding
device wake up ability.
Fix this by:
1. Do not wake up the system via WOL if device wakeup is disabled
2. Make WOL display info from ethtool consistent with device wake up
settings in sysfs
Chen Yu (2
.
This patch clears the WOL ability of this network device if the
user has disabled the wake up ability in sysfs.

v2: According to Peter's review, v1 is racy, if someone already
set TIF_NEED_RESCHED this patch just clear POLLING and go to sleep.
Check TIF_NEED_RESCHED before entering suspend to idle and
adjust the naming
during suspend to idle.
