There is no reason to have the kernel to append commands when running under the simulator, the simulator is perfectly capable of supplying the necessary command line arguments. Furthermore, if the simulator needs something different than what is hard coded in the kernel, it cannot get it if the kernel overrides it. Fix/Simplify the whole thing by removing this bit.

__get_cpu_var() is used for multiple purposes in the kernel source. One of them is address calculation via the form &__get_cpu_var(x). This calculates the address for the instance of the percpu variable of the current processor based on an offset. Other use cases are for storing and retrieving data from the current processors percpu area. __get_cpu_var() can be used as an lvalue when writing data or on the right side of an assignment. __get_cpu_var() is defined as : #define __get_cpu_var(var) (*this_cpu_ptr(&(var))) __get_cpu_var() always only does an address determination. However, store and retrieve operations could use a segment prefix (or global register on other platforms) to avoid the address calculation. this_cpu_write() and this_cpu_read() can directly take an offset into a percpu area and use optimized assembly code to read and write per cpu variables. This patch converts __get_cpu_var into either an explicit address calculation using this_cpu_ptr() or into a use of this_cpu operations that use the offset. Thereby address calculations are avoided and less registers are used when code is generated. At the end of the patch set all uses of __get_cpu_var have been removed so the macro is removed too. The patch set includes passes over all arches as well. Once these operations are used throughout then specialized macros can be defined in non -x86 arches as well in order to optimize per cpu access by f.e. using a global register that may be set to the per cpu base. Transformations done to __get_cpu_var() 1. Determine the address of the percpu instance of the current processor. DEFINE_PER_CPU(int, y); int *x = &__get_cpu_var(y); Converts to int *x = this_cpu_ptr(&y); 2. Same as #1 but this time an array structure is involved. DEFINE_PER_CPU(int, y[20]); int *x = __get_cpu_var(y); Converts to int *x = this_cpu_ptr(y); 3. Retrieve the content of the current processors instance of a per cpu variable. DEFINE_PER_CPU(int, y); int x = __get_cpu_var(y) Converts to int x = __this_cpu_read(y); 4. Retrieve the content of a percpu struct DEFINE_PER_CPU(struct mystruct, y); struct mystruct x = __get_cpu_var(y); Converts to memcpy(&x, this_cpu_ptr(&y), sizeof(x)); 5. Assignment to a per cpu variable DEFINE_PER_CPU(int, y) __get_cpu_var(y) = x; Converts to __this_cpu_write(y, x); 6. Increment/Decrement etc of a per cpu variable DEFINE_PER_CPU(int, y); __get_cpu_var(y)++ Converts to __this_cpu_inc(y) Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: NChristoph Lameter <cl@linux.com> Signed-off-by: NTejun Heo <tj@kernel.org>

The current implementation of irq_set_affinity() refuses rightfully to route an interrupt to an offline cpu. But there is a special case, where this is actually desired. Some of the ARM SoCs have per cpu timers which require setting the affinity during cpu startup where the cpu is not yet in the online mask. If we can't do that, then the local timer interrupt for the about to become online cpu is routed to some random online cpu. The developers of the affected machines tried to work around that issue, but that results in a massive mess in that timer code. We have a yet unused argument in the set_affinity callbacks of the irq chips, which I added back then for a similar reason. It was never required so it got not used. But I'm happy that I never removed it. That allows us to implement a sane handling of the above scenario. So the affected SoC drivers can add the required force handling to their interrupt chip, switch the timer code to irq_force_affinity() and things just work. This does not affect any existing user of irq_set_affinity(). Tagged for stable to allow a simple fix of the affected SoC clock event drivers.

Fix I/O space setup, so that on non-PCI systems using inb()/outb() won't crash the system. Some drivers may try to probe I/O space and for that purpose we can just allocate some normal memory initially. Drivers trying to reserve a region will fail early as we set the size to 0. If a real I/O space is present, the PCI/PCIe support code will re-adjust the values accordingly. Tested with EdgeRouter Lite by enabling CONFIG_SERIO_I8042 that caused the originally reported crash.

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.

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.

Enable interfaces on EdgeRouter Lite. Tested with cavium_octeon_defconfig and busybox shell. DHCP & ping works with eth0, eth1 and eth2. The board type "UBNT_E100" is taken from the sources of the vendor kernel shipped with the product.

Following patch to use generic 8250 drivers will need proper clock information. So when using the internal device tree, populate the "clock-frequency" property with the correct value.

Commit abe77f90 (MIPS: Octeon: Add kexec and kdump support) added a bootmem region for the kernel image itself. The problem is that this is rounded up to a 0x100000 boundary, which is memory that may not be owned by the kernel. Depending on the kernel's configuration based size, this 'extra' memory may contain data passed from the bootloader to the kernel itself, which if clobbered makes the kernel crash in various ways. The fix: Quit rounding the size up, so that we only use memory assigned to the kernel.
