The config symbol was introduced in drivers, but not added to
generic kernel config files. This will halt build asking for the
value.
Fix it by adding the value (setting it to disabled).

Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
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.

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.:

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.

Enabling KERNEL_TRANSPARENT_HUGEPAGE exposes 2 missing symbols:
* CONFIG_READ_ONLY_THP_FOR_FS

* 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.

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:
