This reverts commit 24b91e360ef521a2808771633d76ebc68bd5604b and commit
7bdb59f1ad47 ("tick/nohz: Fix possible missing clock reprog after tick
soft restart") that depends on it,
Pavel reports that it causes occasional boot hangs for him that seem to
depend on just how the machine was booted. In particular, his machine
hangs at around the PCI fixups of the EHCI USB host controller, but only
hangs from cold boot, not from a warm boot.
Thomas Gleixner suspecs it's a CPU hotplug interaction, particularly
since Pavel also saw suspend/resume issues that seem to be related.
We're reverting for now while trying to figure out the root cause.

This driver requires a GPIO line to be used for the chip select of
each SPI device.
Remove the ep93xx_spi_chip_ops definition from the platform data
and use the spi core GPIO handling for the chip selects.
Fix all the ep93xx platforms that use this driver and remove the
old Documentation.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core clang fixes from Arnaldo Carvalho de Melo:
Changes to make tools/{perf,lib/{bpf,traceevent,api}} build with
CC=clang, to, for instance, take advantage of warnings (Arnaldo Carvalho de Melo):
- Conditionally request some warning options not available on clang
- Set the maximum optimization level to -O3 when using CC=clang, leave
the previous setting of -O6 otherwise.
- Make it an error to pass a signed value to OPTION_UINTEGER, so that
we can remove abs(unsigned int) calls in 'perf bench futex'.
- Make sure dprintf() is not defined before using that name in 'perf bench numa'
- Avoid using field after variable sized type, its a GNU extension, use
equivalent code.
- Fix some bugs where some variables could be used unitialized,
something not caught by gcc.
- Fix some spots where we were testing struct->array[] members against
NULL, it will always evaluate to 'true'.
- Add missing parse_events_error() prototype in the bison file.
There are still one problem when trying to build the python support, but
this are the 'size' outputs for 'make -C tools/perf NO_LIBPYTHON' for
gcc and clang builds:

Since we have the MST feature enabled and Pin-Port mux for user to
select the converter routing, multiple port mapping to same converter
needs to be supported.
To support multiple port mapped to same converter following changes are
done for this:.
o Add port list to pcm, so that multiple ports can be mapped to a PCM.
o Jack reporting in case where multiple port are attached to same PCM.
o Change hdac_hdmi_get_port_from_cvt(), channel_map, remove functions
to parse through all ports mapped to same the PCM.

To enable stream on a specific port of a MST capable pin, the port
needs to be selected before we configure the pin widget verb.
When port is selected, all the pin widget verb controlling the sink
device operation will be directed to selected port. So add port
selection before configuring the pin widget verb.

The ELD notification can be received asynchronously from the graphics
side and this may happen just at the moment the sound driver is
initializing and notification will be missed. Similarly at system
resume, the notification is ignored as the ELD and connection states
are updated in anyway at the end of the resume.
So check the jack status in boot/resume by querying the port presence
based on pin caps and report the jack status.

Enabling both DEBUG_WX=y and KASAN=y options significantly increases
boot time (dozens of seconds at least).
KASAN fills kernel page tables with repeated values to map several
TBs of the virtual memory to the single kasan_zero_page:
kasan_zero_pud ->
kasan_zero_pmd->
kasan_zero_pte->
kasan_zero_page
So, the page table walker used to find W+X mapping check the same
kasan_zero_p?d page table entries a lot more than once.
With patch pud walker will skip the pud if it has the same value as
the previous one . Skipping done iff we search for W+X mappings,
so this optimization won't affect the page table dump via debugfs.
This dropped time spend in W+X check from ~30 sec to reasonable 0.1 sec:
Before:
[ 4.579991] Freeing unused kernel memory: 1000K
[ 35.257523] x86/mm: Checked W+X mappings: passed, no W+X pages found.
After:
[ 5.138756] Freeing unused kernel memory: 1000K
[ 5.266496] x86/mm: Checked W+X mappings: passed, no W+X pages found.
