[PATCH RT 0/3] Linux 3.2.83-rt121-rc1

[PATCH RT 0/3] Linux 3.2.83-rt121-rc1

[Steven Rostedt]

Dear RT Folks,

This is the RT stable review cycle of patch 3.2.83-rt121-rc1.

Please scream at me if I messed something up. Please test the patches too.

The -rc release will be uploaded to kernel.org and will be deleted when
the final release is out. This is just a review release (or release candidate).

The pre-releases will not be pushed to the git repository, only the
final release is.

If all goes well, this patch will be converted to the next main release
on 11/2/2016.

Enjoy,

-- Steve

[PATCH RT 1/3] genirq: Fix pointer cast warning for randomness on 32-bit architectures

3.2.83-rt121-rc1 stable review patch.

From: Ben Hutchings <ben@decadent.org.uk>

gcc warns about casting directly from a 32-bit pointer to u64.  In the
current rt patch series we cast to unsigned long to avoid the warning,
but this fix hasn't been backported to all versions.
