2012-12-05m68knommu: add clock creation support macro for other ColdFire CPUsGreg Ungerer1-1/+8
The clock support code for ColdFire CPUs currently supports those that have the clock control register PPMCR. Expose the struct clk for all CPU types and add a definition for all other ColdFire CPU types. With this we will be able to define simple clock trees for all ColdFire CPU types, even though they will not be able to be enabled or disabled. They will be able to report the clock rate.

2012-12-05m68k: fix unused variable warning in mempcy.cGreg Ungerer1-1/+2
When compiling for original 68000 or ColdFire targets you will get the following warning when compiling arch/m68k/lib/memcpy.c: CC arch/m68k/lib/memcpy.o arch/m68k/lib/memcpy.c: In function ‘__builtin_memcpy’: arch/m68k/lib/memcpy.c:13:15: warning: unused variable ‘temp1’ This is easily fixed by moving the definition of temp1 into the code block where it is used.

2012-12-05m68knommu: make non-MMU page_to_virt() return a void *Greg Ungerer1-1/+1
The page_to_virt() macro for m68knommu is currently effectively returning an int type. But the equivilent m68k macro returns a void * virtual address. Modify the non-MMU macro to return a void * as well (using the __va macro). This change will remove compiler warnings in common m68k code that use this macro.

2012-12-05m68knommu: merge ColdFire 5249 and 525x definitionsGreg Ungerer5-282/+124
The ColdFire 5249 and 525x family of SoCs are very similar. Most of the internals are the same, and are mapped the same. We can use a single set of peripheral definitions for all of them. So merge the current m5249sim.h and m525xsim.h definitions into a single file. The 5249 is now obsolete, and the 525x parts are current, so I have chosen to move everything into the existing m525xsim.h file. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2012-11-30x86, fpu: Avoid FPU lazy restore after suspendVincent Palatin2-6/+14
When a cpu enters S3 state, the FPU state is lost. After resuming for S3, if we try to lazy restore the FPU for a process running on the same CPU, this will result in a corrupted FPU context. Ensure that "fpu_owner_task" is properly invalided when (re-)initializing a CPU, so nobody will try to lazy restore a state which doesn't exist in the hardware. Tested with a 64-bit kernel on a 4-core Ivybridge CPU with eagerfpu=off, by doing thousands of suspend/resume cycles with 4 processes doing FPU operations running. Without the patch, a process is killed after a few hundreds cycles by a SIGFPE.

2012-11-28ARM: 7586/1: sp804: set cpumask to cpu_possible_mask for clock event deviceWill Deacon1-1/+1
The SP804 driver statically initialises the cpumask of the clock event device to be cpu_all_mask, which is derived from the compile-time constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt controller handling the sp804 doesn't have the irq_set_affinity callback on the irq_chip, because the common timer code fails to identify the device as cpu-local and ends up treating it as a broadcast device instead. This patch fixes the problem by using cpu_possible_mask at runtime, which will correctly represent the possible CPUs when SMP_ON_UP is being used.

2012-11-27x86-32: Unbreak booting on some 486 clonesH. Peter Anvin1-2/+7
There appear to have been some 486 clones, including the "enhanced" version of Am486, which have CPUID but not CR4. These 486 clones had only the FPU flag, if any, unlike the Intel 486s with CPUID, which also had VME and therefore needed CR4. Therefore, look at the basic CPUID flags and require at least one bit other than bit 0 before we modify CR4. Thanks to Christian Ludloff of sandpile.org for confirming this as a problem.

2012-11-23of/address: sparc: Declare of_iomap as an extern function for sparc againAndreas Larsson1-1/+4
This bug-fix makes sure that of_iomap is defined extern for sparc so that the sparc-specific implementation of_iomap is once again used when including include/linux/of_address.h in a sparc context. OF_GPIO that is now available for sparc relies on this. The bug was inadvertently introduced in a850a75, "of/address: add empty static inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c. This fix takes the same approach as 0bce04b that solved the equivalent problem for of_address_to_resource.

2012-11-23MIPS: Fix crash that occurs when function tracing is enabledAl Cooper1-4/+4
A recent patch changed some irq routines from inlines to functions. These routines are called by the tracer code. Now that they're functions, if they are compiled for function tracing they will call the tracer and crash the system due to infinite recursion. The fix disables tracing in these functions by using "notrace" in the function definition.

2012-11-23MIPS: Merge overlapping bootmem rangesRalf Baechle1-6/+20
Without this, we may end up with something like this in /proc/iomem: 01100000-014fffff : System RAM 01100000-013bf48f : Kernel code 013bf490-0149e01f : Kernel data 01500000-0c0fffff : System RAM but the two System RAM ranges should be one single range. This particular case will result in kexec failure on Octeon systems if the kernel being loaded by kexec is bigger than the already running kernel. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-11-23ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and aboveDave Martin1-1/+13
Modern GCC can generate code which makes use of the CPU's native unaligned memory access capabilities. This is useful for the C decompressor implementations used for unpacking compressed kernels. This patch disables alignment faults and enables the v6 unaligned access model on CPUs which support these features (i.e., v6 and later), allowing full unaligned access support for C code in the decompressor. The decompressor C code must not be built to assume that unaligned access works if support for v5 or older platforms is included in the kernel. For correct code generation, C decompressor code must always use the get_unaligned and put_unaligned accessors when dealing with unaligned pointers, regardless of this patch.
