The event group view feature is to see related events together. To use
the group view, events should be recorded as a group with a dedicated
syntax of surrounding events by braces (-e '{ evt1, evt2, ... }').
Also 'perf report' also requires the --group option to enable it.
However it's almost always beneficial to use the group view to see the
group events as it's more expressive. And I think it's more natural to
see events together if they are recorded as a group.
Thus this patch changes the default value to enable it. If users don't
want to see like it and keep the original behavior, they can set the
report.group config variable to false and/or use --no-group option in
the 'perf report' command line.

Since msleep() may sleep longer than intended time for values less
than 20ms, this patch allows the use of usleep_range for waits less
that 20ms. usleep_range is a finer precision implementation of
msleep and is designed to be a drop-in replacement for udelay
where a precise sleep/busy-wait is unnecessary.

Add a defconfig covering all known pxa board, ie. all selectable machine

- aggregation of all known defconfigs by cat
am200epdkit_defconfig
cm_x2xx_defconfig
cm_x300_defconfig
colibri_pxa270_defconfig
colibri_pxa300_defconfig

pxa255-idp_defconfig
pxa3xx_defconfig
raumfeld_defconfig
spitz_defconfig
trizeps4_defconfig
viper_defconfig
xcep_defconfig
zeus_defconfig
- manual make menuconfig to ensure :
- all pxa implementation were selected
- all drivers were transformed into modules rather than builtin
=> as a consequence this single kernel will rely on an initramfs
=> as kernel size matters on pxa, each machine can take the subset
of modules required for it to work
- all missed configurations are selected verified by :
=> grep -i pxa .config | grep "is not set"
=> this should only show the left on purpose options (either not
selectable or sharpsl exception below)
- CONFIG_PXA_SHARPSL was disabled
This breaks the boot very early on any non Sharp platform, see
head-sharpsl.S
This defconfig was tested as booting up to the login phase on :
- lubbock (pxa25x)
- mainstone (pxa27x)
- zylonite (pxa3xx)
The completion of this work will require to :
- parse manually all the arch/arm/mach-pxa/*c files, look for all
platform devices added, and verify they are all in pxa_defconfig
- do the same to ensure all pxa specific drivers (leds, gpio, ...) are
included

This is the i40e equivalent of commit c762dff24c ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").
As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.
In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.
The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.
