99ca423387 perf symbols: Export elf_section_by_name and reuse
Remove duplicated elf_section_by_name() functions from unwind.c and
probe-event.c and use one exported elf_section_by_name() instance
defined in symbol-elf.c.

Note that this also moves get_text_start_address() to merge
HAVE_DWARF_SUPPORT defined area.

a7077234d2 perf tools: Add 'build-test' make target
Currently various build test can be performed using a Makefile named
tests/make, so one needs to remember and specify it with -f option on
command line.

Add the 'build-test' target in the main Makefile as a shortcut.

4ce00dfcf1 Revert "arm64: Fix memory shareability attribute for ioremap_wc/cache"
This reverts commit 2f7dc60275.

The above commit breaks the mapping type for Device memory because
pgprot_default already contains a Normal memory type. pgprot_default is
also not initialised early enough for earlyprintk resulting in an
inconsistent memory mapping with 64K PAGE_SIZE configuration.

eaad45132c sched: Fix __sched_setscheduler() nice test
With the introduction of sched_attr::sched_nice we need to check
if we've got permission to actually change the nice value.

Daniel found that can_nice() would always fail; and upon
inspection it turns out that can_nice() only tests to see if we
can lower the nice value, but it doesn't validate if we're
lowering or not.

Therefore amend the test to only call can_nice() when we lower
the nice value.

63b1a81699 futexes: Fix futex_hashsize initialization
"futexes: Increase hash table size for better performance"
introduces a new alloc_large_system_hash() call.

alloc_large_system_hash() however may allocate less memory than
requested, e.g. limited by MAX_ORDER.

Hence pass a pointer to alloc_large_system_hash() which will
contain the hash shift when the function returns. Afterwards
correctly set futex_hashsize.

Fixes a crash on s390 where the requested allocation size was
4MB but only 1MB was allocated.

54b1aa5a5b ARM: pinctrl: Add Broadcom Capri pinctrl driver
Adds pinctrl driver for Broadcom Capri (BCM281xx) SoCs.

v4: - PINCTRL selected in Kconfig, PINCTRL_CAPRI selected in bcm_defconfig
    - make use of regmap
    - change CAPRI_PIN_UPDATE from macro to inline function.
    - Handle pull-up strength arg in Ohm instead of enum
v3: Re-work driver to be based on generic pin config. Moved config selection
    from Kconfig to bcm_defconfig.
v2: Use hyphens instead of underscore in DT property names.

9bb412e557 pinctrl: Add pinctrl binding for Broadcom Capri SoCs
Adds pinctrl driver devicetree binding for Broadcom Capri (BCM281xx) SoCs.

v4: Changed valid values for "bias-pull-up" property for I2C pins.
    Expanded pin configuration node example.
v3: Use generic pin config properties instead of brcm-specific ones.
    Clarified pin types (standard, i2c, hdmi).
v2: Use hyphens instead of underscore in DT property names.

c48ae0ab37 ALSA: hda - add headset mic detect quirks for some Dell machines
When we plug a 3-ring headset on some Dell machines, the headset
mic can't be detected, after apply this patch, the headset mic
can work well on all those machines.

On the machine with the Subsytem ID 0x10280610, if we use
ALC269_FIXUP_DELL1_MIC_NO_PRESENCE, the headset mic can be
detected and work well, but the sound can't be outputed via
headphone anymore, use ALC269_FIXUP_DELL3_MIC_NO_PRESENCE
can fix this problem.

7479f3c9cf sched: Move SCHED_RESET_ON_FORK into attr::sched_flags
I noticed the new sched_{set,get}attr() calls didn't properly deal
with the SCHED_RESET_ON_FORK hack.

Instead of propagating the flags in high bits nonsense use the brand
spanking new attr::sched_flags field.

0bb040a443 sched: Fix up attr::sched_priority warning
Fengguang Wu reported the following build warning:

  > kernel/sched/core.c:3067 __sched_setscheduler() warn: unsigned 'attr->sched_priority' is never less than zero.

Since it doesn't make sense for attr::sched_priority to be negative,
remove the check, since we already test for an upper limit any actual
negative values passed in through the old param::sched_priority field
will still be detected.

39fd8fd22b sched: Fix up scheduler syscall LTP fails
Wu reported LTP failures:

  > ltp.sched_setparam02.1.TFAIL
  > ltp.sched_setparam02.2.TFAIL
  > ltp.sched_setparam02.3.TFAIL
  > ltp.sched_setparam03.1.TFAIL

There were 2 things wrong; firstly __setscheduler() failed on
sched_setparam()'s policy = -1, fix that by reading from p->policy in
that case.

Secondly, getparam() (and getattr()) would still report !0
sched_priority for !FIFO/RR tasks after having been such. So
unconditionally set p->rt_priority.
