These upstream patches makes the RTL8366RB DSA switch work
properly with OpenWrt, the D-Link DIR-685 gets network and
can be used as a router, and the same should be applicable
for any other device that want to enable the RTL8366RB
through Device Tree.

The malta subtargets for mips64 and mips64el fail to start the init process
at boot, resulting in a boot loop. The issue was raised and analyzed within
FS#3277. Investigation suggested code near the [vdso] memory area of the
process was long jumping into a region inaccessible to the process, e.g.
init: - preinit -
init: Launched preinit instance, pid=522
do_page_fault(): sending SIGSEGV to init for invalid read access from 0000000000000360
epc = 0000000000000360 in init[aaab42b000+4000]
ra = 000000fffee385e0 in
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
Rebooting in 1 seconds..
Note the low-memory read access and epc are the same. Upstream kernel 5.6
included a relevant patch and discussion:
* d3f703c4359f ("mips: vdso: fix 'jalr t9' crash in vdso code")
Disassembly of the failing kernel's vdso.so confirmed presence of the
telltale long jumps, e.g.:
00000000000007c0 <__vdso_clock_getres@@LINUX_2.6>:
[...]
7dc: 0320f809 jalr t9

After those symbols have been removed from generic kernel config,
they were added to the target config during every kernel config
refresh. As that's not desirable, add them back to the generic
config.

In commit 87b35c16ad ("kernel: ubifs: create use file system format 4
by default") we changed the default UBIFS version used when the kernel
creates a new volume from 5 to 4. UBIFS v5 was added in kernel 4.10 and
only kernel 4.10 and later can read it.
We changed the kernel to create version 4 volumes also on more recent
kernel versions to make it possible to downgrade to an OpenWrt version
with kernel 4.9, the upgrade still works. This is probably not needed
any more and we can remove this patch.

This symbol is exposed on ARM64 with EFI enabled in the kernel config.
Currently this happens only on ipq807x, but as there might be new ARM64
targets with EFI in the future it is better to add the symbol to the
generic config.

Don't explicitely disable options in target/linux/generic/config-* if
they are already controlled in config/Config-kernel.in.
Add a bunch of new symbols and prepare defaults for using only unified
hierarchy (ie. cgroup2). Update symbol dependencies while at it

Kernel v5.1 included an eBPF JIT for MIPS32 kernels, but problems were
discovered [1] and the changes later reverted in kernel v5.5 with commits:
* f8fffebdea75 ("MIPS: BPF: Disable MIPS32 eBPF JIT")
* 36366e367ee9 ("MIPS: BPF: Restore MIPS32 cBPF JIT")
Only the first of these was backported to LTS kernel 5.4, leaving cBPF
programs without a JIT and introducing a performance regression for any
such users e.g. libpcap, tcpdump, etc.
Restore cBPF performance by backporting the second commit above:
* 070-v5.5-MIPS-BPF-Restore-MIPS32-cBPF-JIT.patch
