As the function itself says it is caller's responsibility to call the
of_node_put(). So, remove it on success to keep the reference count
correct.

The crypto node now contains a new property 'fsl,sec-era'.
This is required so that applications can retrieve era info without
having to be able to read SEC's register space.

In perf_ip_adjust() we potentially use the MMCRA[SLOT] field to adjust
the reported IP of a sampled instruction.
Currently the logic is written so that if the backend does NOT have
the PPMU_ALT_SIPR flag set then we assume MMCRA[SLOT] exists.
This is wrong on power7, where we have SIPR in the "al

When the fadump is enabled, we have /sys/kernel/fadump_enabled assigned 1.
But sometimes we need to restart the fadump service by 'service kdump restart',
in case the kdump script has added the fadump detect/support already.
In current implementation, we cannot re-assign 1 to /sys/kernel/fadump_en

Hi Scott,
I added load instruction handler for the skipped instruction.
For now most common load instructions are handled in this patch.
Any advice for this?
Thanks.

MPIC version is useful information for both mpic_alloc() and mpic_init().
The patch provide an API to get MPIC version for reusing the code.
Also, some other IP block may need MPIC version for their own use.
The API for external use is also provided.

Call of_node_put() only when the out_args is NULL on success,
or the node's reference count will not be correct because the caller
will call of_node_put() again.

__remove_pages() is only necessary for CONFIG_MEMORY_HOTREMOVE. PowerPC
pseries will return -EOPNOTSUPP if unsupported.
Adding an #ifdef causes several other functions it depends on to also
become unnecessary, which saves in .text when disabled (it's disabled in
most defconfigs besides powerpc, i
