[ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI initialisation
Whereas most Orion 5x machine support code would initialise the PCI
subsystem with nr_controllers in their struct hw_pci set to 2, the
DNS323 and Kurobox Pro machine support code had nr_controllers set
to 1.
This was presumably done because on those two machines, the PCI(-X)
controller (nr == 1) isn't used, requiring initialisation of only
the PCIe controller (nr == 0.) However, not initialising the PCI(-X)
controller on boards that don't use it leads to a situation where
both the PCIe and the PCI(-X) controller think that their root bus is
zero, and it messes up IRQ assignment.

use nr_controllers == 2.

x86: disable mwait for AMD family 10H/11H CPUs
The previous revert of
0c07ee38c9d4eb081758f5ad14bbffa7197e1aec left
out the mwait disable condition for AMD family 10H/11H CPUs.
Andreas Herrman said:
It depends on the CPU. For AMD CPUs that support MWAIT this is wrong.
Family 0x10 and 0x11 CPUs will enter C1 on HLT. Powersavings then
depend on a clock divisor and current Pstate of the core.
If all cores of a processor are in halt state (C1) the processor can
enter the C1E (C1 enhanced) state. If mwait is used this will never
happen.
Thus HLT saves more power than MWAIT here.
It might be best to switch off the mwait flag for these AMD CPU
families like it was introduced with commit
f039b754714a422959027cb18bb33760eb8153f0 (x86: Don't use MWAIT on AMD

initcalls: Fix m68k build and possible buffer overflow
This patch fixes a build bug on m68k - gcc decides to emit a call to the
strlen library function, which we don't implement.
More importantly - my previous patch "init: don't lose initcall return
values" (commit
e662e1cfd434aa234b72fbc781f1d70211cb785b) had introduced
potential buffer overflow by wrong calculation of string accumulator
size.
Use strlcat() instead, fixing both bugs.
Many thanks Andreas Schwab and Geert Uytterhoeven for helping
to catch and fix the bug.
