KVM_COMPAT apparently enables 32-bit compability syscalls for KVM, and
as such can be enabled only on a 64-bit system.

IKCONFIG must be enabled so IKCONFIG_PROC can be set. On x86 IKCONFIG
gets implicitly enabled by kernelAutoModules in platforms.nix. But ARM
doesn't use kernelAutoModules, so IKCONFIG_PROC won't get enabled
without this patch.
Commit 159fed47bc (nixos/grub: Fix video display on efi) changed BIOS
systems to start in non-text mode as well. Enable FB_VESA to get a
framebuffer console on BIOS systems. Change FRAMEBUFFER_CONSOLE to 'y'
instead of the default 'm' to so the user doesn't need to manually load
the fbcon module anymore.
Other distros have similar defaults, at least on Arch:
CONFIG_FB_VESA=y
CONFIG_FRAMEBUFFER_CONSOLE=y
and on Ubuntu (12.04):
CONFIG_FB_VESA=m
CONFIG_FRAMEBUFFER_CONSOLE=y
Fixes#8139
Also build the performance governor into the kernel so there is a sane
default. Note that cpufreq.service will still load "ondemand" on
non-pstate systems.
The option has been removed in torvalds/linux@6cd176a and thus we
shouldn't try to set it for kernel version 4.

Using linux-testing for a bunch of machines, I'd actually expect it to
be more recent than the latest stable, but until now it actually was
behind.
Since torvalds/linux@464ed18ebd, the option
PM_RUNTIME doesn't exist anymore, so we need to remove it from our
common config.

We don't really need this anymore, except that our docs say that you
can put firmware in /root/test-firmware, which doesn't work via
/sys/module/firmware_class/parameters/path.
This should only be temporary, but there's a bug in the 3.17 rc1 and rc2 that leads to cyclic module dependencies and a segfault during the build process.
I'm only enabling for kernels >= 3.11 to be conservative, because clients and
servers automatically negotiate and use the highest mutually supported version
by default, but only in kernel 3.11 server NFSv4.1 support actually became RFC
compliant.
I'm also adding support for swap on NFS, which is enabled by default on
Ubuntu kernels.
