This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.
This reduces the attack surface on such systems and should also save
some memory.

perf/core: Rename CONFIG_[UK]PROBE_EVENT to CONFIG_[UK]PROBE_EVENTS
We have uses of CONFIG_UPROBE_EVENT and CONFIG_KPROBE_EVENT as
well as CONFIG_UPROBE_EVENTS and CONFIG_KPROBE_EVENTS.
Consistently use the plurals.
So I'm changing it to this plural option in order to make kconfig happy
and stop asking about it if kernel is compiled with verbose logging:
Enable uprobes-based dynamic events (UPROBE_EVENTS) [Y/n/?] (NEW)

Currently it's not possible to use perf on ath79 due to genirq flags
mismatch happening on static virtual IRQ 13 which is used for
performance counters hardware IRQ 5.

This problem is happening, because currently statically assigned virtual
IRQ 13 for performance counters is not claimed during the initialization
of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that
this interrupt isn't available for further use.
So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.

Please note that modified code isn't currently being compiled with

This applies to ar8216 and ar8236. QCA's newer U-boot will enable
the switch mdio master for FE switches which makes phy inaccessible
from CPU mdio. (e.g. on TP-Link TL-WR941N v7 Chinese version which
uses QCA9558+AR8236.) For these devices PHY probing is broken and
mdio device probing is a must. We also need to disable switch mdio
master in driver for later PHY initialization.
Do a soft reset during hw_init so that mdio master can be disabled
and expose PHYs to CPU mdio for later PHY accessing.

Partially reverts commit eff3549c58.
AR7240 and AR9341 have buggy hardware switch LED trigger. The AR7240
one doesn't blink and the blinking of port0/port5 is reversed on
AR9341 if we swap PHY0 and PHY4. (Only blinking is reversed, which
means LED for PHY0 will lit when PHY0 is link up and will blink when
PHY4 has active link and vice versa.) On these two chips a software
swconfig LED trigger is required.
This commit adds swconfig port stats back but:
1. move checking of mib_t/rxb_id into ar8xxx_chip since we can't
distinguish ar7240sw and ar8216 using only chip id.
2. don't update mib counter in get_port_stat. This function is called
every 0.01s and this capturing procedure will take up a lot of CPU.
We already have a mib_work_func updating mib counters every 2s so
return the saved counter instead of fetching new data. The blinking
rate will be weird but it should solve the previously mentioned CPU
time problem.

This builtin switch is a bugless ar8216 with different mib counters
and gigabit cpu port.
Atheros uses the same device ID and it's impossible to distinguish
the standalone one and the builtin one. So we add support to mdio
device probe only.
This switch doesn't have buggy vlan tag so it's not needed to enable
atheros header. This commit changed ar8216_setup_port so that it can
be reused for this switch.

Atheros FE switches have a builtin mdio master available for PHY
accessing and on ar724x/ar933x builtin switches this mdio master
is the only way of accessing PHYs.
After this patch if there is phy_read/phy_write method available
in ar8xxx_chip we register a separated mdio bus for accessing PHYs.
Still adds support for mdio device probing only since this isn't
needed for those switches registered using PHY probing.

ar8229 is the builtin switch in ar934x and later chips. There is
also a standalone version available and their registers/functions
are the same.
This commit added support for the builtin ar8229. The only thing
missing for standalone ar8229 should be phy modes. Since I don't
have a router using that, this commit doesn't add support for
other phy modes.
Only add its support for mdio-device probing method because the
current PHY probing can't return 1G speed when it's a FE switch.
