Virtualization does not always need KVM capabilities so drop the dependency. The KVM symbol already depends on HAVE_KVM.

During the pruning of the device tree octeon_fdt_pip_iface() is called for each PIP interface and every port up to the port count is removed from the device tree. However, the count was set to the return value of cvmx_helper_interface_enumerate() which doesn't actually return the count but just returns zero on success. This effectively removed *all* ports from the tree. Use cvmx_helper_ports_on_interface() instead to fix this. This successfully restores the 3 ports of my ERLite-3 and fixes the "kernel assigns random MAC addresses" issue.

Make KVM_GUEST depend on BROKEN_ON_SMP so that it cannot be enabled with SMP. SMP kernels use ll/sc instructions for an atomic section in the tlb fill handler, with a tlbp instruction contained in the middle. This cannot be emulated with trap & emulate KVM because the tlbp instruction traps and the eret to return to the guest code clears the LLbit which makes the sc instruction always fail.

Commit 4df715aa ["MIPS: BMIPS: support booting from physical CPU other than 0"] introduced a thinko which will prevents slave CPUs from being released from reset on systems where we boot from TP0. The problem is that we are checking whether the slave CPU logical CPU map is 0, which is never true for systems booting from TP0, so we do not release the slave TP from reset and we are just stuck. Fix this by properly checking that the CPU we intend to boot really is the physical slave CPU (logical and physical value being 1).

commit 3747069b25e419f6b51395f48127e9812abc3596 upstream. The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. Here, we remove all the MIPS __cpuinit from C code and __CPUINIT from asm files. MIPS is interesting in this respect, because there are also uasm users hiding behind their own renamed versions of the __cpuinit macros.

Original posting: http://lkml.kernel.org/r/20121214184202.F54094D9@kernel.stglabs.ibm.com Several architectures have similar stack debugging config options. They all pretty much do the same thing, some with slightly differing help text. This patch changes the architectures to instead enable a Kconfig boolean, and then use that boolean in the generic Kconfig.debug to present the actual menu option.

BMIPS43xx CPUs have two hardware threads, and on some SoCs such as 3368, the bootloader has configured the system to boot from TP1 instead of the more usual TP0. Create the physical to logical CPU mapping to cope with that, do not remap the software interrupts to be cross CPUs such that we do not have to do use the logical CPU mapping further down the code, and finally, reset the slave TP1 only if booted from TP0.

As Jonas Gorske said in his patch: Disable cpu_has_mmips for everything but SEAD3 and MALTA. Most of these platforms are from before the micromips introduction, so they are very unlikely to implement it. Reduces an -Os compiled, uncompressed kernel image by 8KiB for BCM63XX. This patch taks a different approach than his, we gate the runtime test for microMIPS by the config symbol SYS_SUPPORTS_MICROMIPS.

There is an infinite loop in gic_set_affinity. When irq_set_affinity gets called on gic controller, it blocks forever. Signed-off-by: NTony Wu <tung7970@gmail.com> Cc: Steven J.
