e788e9bd87 treewide: enable the vDSO
The vDSO is used to accelerate some syscalls. It should work fine wherever it's
available, so enable it globally for all targets.

0f5b5cf730 kernel: clean up XATTR config symbols
Extended attributes are required for overlayfs and have hence been long
ago enabled for jffs2, but should be enabled unconditionally for all
other filesystems which may potentially serve as overlayfs' upper
directory. Previously it was inconsistently added in multiple targets.
Add symbols to generic kernel config and remove all *_XATTR symbols
from target configs.

bf2870c1d9 kernel: fix mtd partition erase < parent_erasesize writes
This bug applied where mtd partition end address,
or erase start address, was not cleanly divisible by parent mtd erasesize.

This error would cause the bits following the end of the partition
to the next erasesize block boundary to be erased,
and this partition-overflow data to be written to the partition erase
address (missing additional partition offset address)
of the mtd (top) parent device.

3f7047db7a kernel: mtdsplit: support ELF loader splitting
To parse the ELF kernel loader, a small ELF parser is used that can
handle both ELF32 or ELF64 class loaders. The splitter assumes that the
kernel is always located before the rootfs, whether it is embedded in
the loader or not. If the kernel is located after the rootfs on the
firmware partition, then the rootfs splitter will include it in the
dynamically created rootfs_data partition and the kernel will be
corrupted.

The kernel image is preferably embedded inside the ELF loader, so the
end of the loader equals the end of the kernel partition. This is due to
the way mtd_find_rootfs_from searches for the the rootfs:
- if the kernel image is embedded in the loader, the appended rootfs may
  follow the loader immediately, within the same erase block.
- if the kernel image is not embedded in the loader, but placed at some
  offset behind the loader (OKLI-style loader), the rootfs must be
  aligned to an erase-block after the loader and kernel image.

In case section header table is empty, determine the elf loader size by
finding the end of the last segment, as defined by the program header
table.

2932b4d05e kernel: mips: fix init crash/bootloop on 64-bit systems
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

In commit 87b35c16ad ("kernel: ubifs: create use file system format 4

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.

5c3e83fa88 kernel: fix missing TRANSPARENT_HUGEPAGE symbols
Enabling KERNEL_TRANSPARENT_HUGEPAGE exposes 2 missing symbols:
* CONFIG_READ_ONLY_THP_FOR_FS
* TRANSPARENT_HUGEPAGE_ALWAYS
* TRANSPARENT_HUGEPAGE_MADVISE

The first one was added in 5.4, and is marked experimental there so just
disable it in the generic config.

For the latter two, we should not force the user to use either of them,
so add them as build-configurable kernel options.

1bff9f5b78 kernel: add missing config symbol
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.

a4856dab0d kernel: mips: restore missing MIPS32 cBPF JIT
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
