Dear RT Folks,
I'm pleased to announce the 3.4.75-rt93 stable release.
This release is just an update to the new stable 3.4.75 version
and no RT specific changes have been made.
You can get this release via the git tree at:

branch: v3.4-rt
Head SHA1: 9d111c9c3814158097723d27029a9d214a8cd20e
Or to build 3.4.75-rt93 directly, the following patches should be applied:
http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.4.tar.xz
http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.4.75.xz

Hello,
I updated from 3.4.69-rt86 to 3.4.75-rt93 on an iMX.537 ARM platform.
Basically the kernel works but I get the following error messages during
boot:
Mount-cache hash table entries: 512
CPU: Testing write buffer coherency: ok
ftrace: allocating 13405 entries in 40 pages

Strange, it tried to convert ftrace_swap_recs, but that should not have
been even in the table to modify, as ftrace_swap_recs is in ftrace.c,
which disables all -pg added in the compile.
Try a make clean and build again. Something may have been screwed up in
the compile.
