The PPPIOCDETACH ioctl effectively tries to "close" the given ppp file
before f_count has reached 0, which is fundamentally a bad idea. It
does check 'f_count < 2', which excludes concurrent operations on the
file since they would only be possible with a shared fd table, in wh

Hi Robert,
Please refer to the attached patch instead of the one I sent earlier. I
missed to also remove the platform_get_resource(IORESOURCE_DMA) call.
Thanks,
Daniel

Hi all,
I bisected the n900 LCD issue to commit 24aac6011f70 ("drm: omapdrm:
sdi: Allocate the sdi private data structure dynamically"). Reverting
this patch makes LCD work for me again on n900.
Any ideas?

Tony

H. Peter,
It was reported [0] that compiling the Linux kernel with Clang +
CC_STACKPROTECTOR_STRONG was causing a crash in native_save_fl(), due to
how GCC does not emit a stack guard for static inline functions (see
Alistair's excellent report in [1]) but Clang does.

Every once in a while, we should update the examples
to reflect more recent kernel versions.
Update the tables describing kernel releases, the merge window,
and current longterm maintained kernel, from 2.6-era kernels
to 4.x.
