[PATCH RT 0/3] Linux 3.10.104-rt117-rc1

[Steven Rostedt]

Dear RT Folks,

This is the RT stable review cycle of patch 3.10.104-rt117-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 2/3] kbuild: add -fno-PIE

[Steven Rostedt]

[-- Attachment #1: 0002-kbuild-add-fno-PIE.patch --]
[-- Type: text/plain, Size: 988 bytes --]

3.10.104-rt117-rc1 stable review patch.
If anyone has any objections, please let me know.

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

Debian started to build the gcc with -fPIE by default so the kernel
build ends before it starts properly with:
|kernel/bounds.c:1:0: error: code model kernel does not support PIC mode
