Two changes are necessary to enable proper operation of the DM9000 device with
the Colibri PXA 270 board: firstly, the IRQ type needs to be configured for
rising edge interrupts, and secondly this configuration needs to be

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.This patch changes the DNS323 and Kurobox Pro support code to always
use nr_controllers == 2.Signed-off-by: Lennert Buytenhek

The CPU's dma_flush_range() operation needs to clean+invalidate the
given memory area if the cache is in writeback mode, or do just the
invalidate part if the cache is in writethrough mode, but the current
proc-arm{925,926,940,946} (incorrectly) do a cache clean in the
latter case. This patch fixes that.Signed-off-by: Lennert Buytenhek

x86: disable mwait for AMD family 10H/11H CPUs
x86: fix crash on cpu hotplug on pat-incapable machines
x86: remove mwait capability C-state check -
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
Family 10)Re-add the AMD families 10H/11H check and disable the mwait usage for
those.Signed-off-by: Thomas Gleixner

pat_disable() is __init, which means it goes away after booting is complete.
Unfortunately it is used by the hotplug code if the machine is not
pat-capable, causing a crash.Fix by marking pat_disable() as __cpuinit.

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.

Everybody wants to pass it a function pointer, and in fact, that is what
you _must_ pass it for it to make sense (since it knows that ia64 and
ppc64 use descriptors for function pointers and fetches the actual
address from there).So don't make the argument be a 'unsigned long' and force everybody to
add a cast.Signed-off-by: Linus Torvalds
