Support for stack protector has been added for ppc, so we enable that.

* Use Westwood+ as default TCP cc algo, instead of CUBIC.
* Ensure JFS and XFS are =y.
* Allow all users to read dmesg.
* Enable ALi PATA controller on pmmx.

This is an attempt at syncing the kernel configs of our different
arches. So far, only the 'Networking support/Networking options',
'Filesystems', 'Security Options' and 'Cryptographic API' sections have
been handled, since those require much less knowledge about some of the
more exotic hardware we support than some of the other sections.
Some notable changes:
Network
* Enable IPsec, miscellaneous tunnels, and the diag interfaces for all
socket families.
* Enable policy routing (for wireguard).
* Make the CUBIC TCP congestion control algorithm the default
everywhere, provide a few other common choices.
* Support FQ_CODEL. We may want to support further QoS features.
* Disable support for PF_KEY sockets, which shouldn't be required by our
IPsec userland tools.
* Enable most netfilter features, except for arptables/ebtables/nfacct/
nfqueue/ipset, whose userland tools we don't provide yet, and a few
other very specialized options.
Filesystems
* Build everything except for ext4, iso9660, vfat and squashfs as
modules.
* Use the ext4 driver for ext2 filesystems.
* Disable the kernel automounter, which is currently only enabled on
ppc32 and aarch64.
Security
* Only grant root access to dmesg by default; this can be overriden via
a sysctl.
* Support Yama; it doesn't do anything unless explicitly enabled by a
sysctl, and may be useful to some users.
* Disable AppAarmor, which is currently only enabled on pmmx and x86_64.
Crypto
* Disable a lot of uncommon ciphers which are unlikely to be used by
anything.
* Build all crypto code as modules (where possible); this means users
with a dm-crypt-encrypted root filesystem now need to provide the
appropriate kernel modules in their initramfs images on all arches.
* Disable support for dedicated cryptographic coprocessors; we are not
in a position to evaluate their security and performance benefits or
disadvantages.
Other
* Allow serial consoles to be used as the kernel console on all arches;
this is important for VMs.

The SKCIPHER and HASH components are required for cryptsetup/dm-crypt,
and there's no reason not to enable RNG and AEAD as well.
