It should be in encoded format since only the algorithms should
be decoding it. Otherwise you have craziness where RSA-specific

earlyprintk messages are not appearing on the terminal
emulator during a big endian kernel boot. In BE mode
sending full words to UART will result in unprintable

The existing code puts all devices from a root PE to the same IOMMU group.
However it is a possible situation when subordinate buses belong to

I recently upgraded my main server to 4.0.4 from 3.19.5 and rkhunter
started reporting a hidden port on my box.
Running unhide-tcp I see this:

Hi Brian,
Today's linux-next merge of the l2-mtd tree got a conflict in MAINTAINERS
between commit 68c2d21d0126 "MIPS: BCM47xx: Move NVRAM driver to the
drivers/firmware/" from the mips tree and commit 02787daadbda "MAINTAINERS: add
entry for new brcmnand/ directory" from the l2-mtd tree.
I fixed

'make build-test' finds an error that make_python_perf_so fails due to
missing of libtraceevent-dynamic-list:

Currently, CONFIG_RTC_SYSTOHC uses CONFIG_RTC_HCTOSYS_DEVICE which
is originally used by CONFIG_RTC_HCTOSYS, but this rtc device has
some limiations, for example, it must be battery-backed, be able
to work with irq off and through system suspension, etc.
So add CONFIG_RTC_SYSTO

On Sparc systems, update_persistent_clock() uses RTC drivers to do
the job, it makes more sense to hand it over to CONFIG_RTC_SYSTOHC.
In the long run, all the update_persistent_clock() should migrate to
proper class RTC drivers if any and use CONFIG_RTC_SYSTOHC instead.

Now rtc_set_mmss() has no users, just remove it.
We still have rtc_set_time() doing similar things.

The fuzzer turned these up (this is 4.1-rc7 with the fasync patch
applied) on a Haswell. I'm listing the crash first, but the warning
happened earlier, not sure if it is related.
