Revert "kernel: Use <caution> for make defconfig and..." 
This reverts commit d0a9bda4e6.

"Don't change anything enabled by defconfig" seems too strong.

Revert "Suggest make localmodconfig for kernel" 
This reverts commit de679165f9.

localmodconfig does not work very well.  It can only *un*select things
already enabled as modules if the module is not loaded by the host.  It
won't select anything new, nor unselect unneeded things already set to
"y" instead of "m".

Maybe you think we can copy .config from a "mainstream" distro
(producing a highly modular kernel) and use "make localmodconfig", but
when we tested it with a Debian host kernel config, the resulted kernel
refuses to boot.

"make allmodconfig && make localmodconfig" does not work well either:
"allmodconfig" selects many things as y (these thing are not available
as a module) but "localmodconfig" fails to unselect them.

de679165f9 Suggest make localmodconfig for kernel 
This is less generic than defconfig, and you can then tell
not to tweak options...

Yes, I messed them up and shot my own foot.

kernel: Recommend to disable CONFIG_EXPERT 
Let's not encourage users to try tricky things and shoot their own foot.

For systemd, if CONFIG_EXPERT is disable, CONFIG_FHANDLE will be enabled
automatically.  So there is no need to enable CONFIG_EXPERT and then set
CONFIG_FHANDLE manually.

kernel: adjust the instruction for mounting /boot 
LFS and the host may use different /boot configuration, so do not assume
they'll share a /boot partition (two different /boot partition or only one
with separate /boot are possible).

linux kernel: enable CONFIG_X86_X2APIC 
It's recommended for CVE-2022-21233 mitigation.  And, if the BIOS has
enabled x2APIC but CONFIG_X86_X2APIC=n, the kernel will panic on boot.

If x2APIC is disabled or not available, the kernel with
CONFIG_X86_X2APIC=y can still boot normally.

No need to tag anything again because interrupt handling cannot affect
userspace.

kernel: disable CONFIG_WERROR 
The help of this options says:

"However, if you have a new compiler with ..., you may need to disable
this config option in order to successfully build the kernel."

As we are having state-of-art GCC-12, and Linux-5.18 release candidate
FTBFS with GCC-12 and CONFIG_WERROR=y [1], and <rant>the kernel developers
are making stupid and meaningless discussion instead of fixing the building
failure</rant> [2], I don't think enabling this option makes any sense
building LFS.
