Add cpufreq driver for Freescale e500mc, e5500 and e6500 SoCs
which are capable of changing the frequency of CPU dynamically

v3:
- change sizeof(struct name).. to sizeof(*p)
- remove the struct cpufreq_
The size might be 64 bit, so use ilog2() instead of __ilog2() or
__ilog2_u64().
ilog2() can select 32bit or 64bit funciton automatically.

Yes yes, Kcalloc is okay... I have misread that part earlier when i
suggested kzalloc.
In last mail i was referring to sizeof() only.

You are correct that it should not be freed with kfree(). But the
correct solution is that it does not need to be freed (explicitly) at
all. That's the whole

The 'perf' tool has some built-in test cases and one of them checks to
see if the symbols in vmlinux match those in /proc/kallsyms.
This test is failing on Power for several reasons. I fixed a couple of
them (described briefly at the end of the mail) and these fixes take
the test further.

Added the following domain attributes for the FSL PAMU driver:
1. Added new iommu stash attribute, which allows setting of the
LIODN specific stash id parameter through IOMMU API.
2. Added an attribute for enabling/disabling DMA to a particular
memory window.
3. Added domain attribute to chec
Each iommu window can have access permissions associated with it. Extended the
window_enable API to incorporate window access permissions.
In case of PAMU each window can have its specific set of permissions.

drivers/iommu/i
Add an iommu domain pointer to device (powerpc) archdata. Devices
are attached to iommu domains and this pointer provides a mechanism
to correlate between a device and the associated iommu domain. This
field is set when a device is attached to a domain.

This is required in case of PAMU, as it can support a window size of up
to 64G (even on 32bit).

This patchset provides the Freescale PAMU (Peripheral Access Management Unit)
driver
and the corresponding IOMMU API implementation. PAMU is the IOMMU present on
Freescale
QorIQ platforms. PAMU can authorize memory access, remap the memory address,
and remap
the I/O transaction type.

Hi all,
We're running into an problem with a (somewhat complicated) 32-bit powerpc
binary.
When we try to run it, it hits the null-terminated interpreter test in the
kernel and
bails out with ENOEXEC.
Looking at the binary with readelf, the program headers contain the following:
