Subject: [PATCH 24/43] tracehook_signal_handler: Remove sig, info, ka and regs

From: Richard Weinberger <[email protected]>

These parameters are nowhere used, so we can remove them.

Subject: [PATCH 12/43] microblaze: Use get_signal() signal_setup_done()

2014-07-21 14:15:31

by Richard Weinberger

[permalink] [raw]

Subject: [PATCH 09/43] ia64: Use get_signal() signal_setup_done()

From: Richard Weinberger <[email protected]>

Use the more generic functions get_signal() signal_setup_done()
for signal delivery.
This inverts also the return codes of force_sigsegv_info()
and setup_frame() to follow the kernel convention.

Added from today. But I would prefer a more generic branch name if it
ever changes.

Thanks for adding your subsystem tree as a participant of linux-next. As
you may know, this is not a judgment of your code. The purpose of
linux-next is for integration testing and to lower the impact of
conflicts between subsystems in the next merge window.

You will need to ensure that the patches/commits in your tree/series have
been:
* submitted under GPL v2 (or later) and include the Contributor's
Signed-off-by,
* posted to the relevant mailing list,
* reviewed by you (or another maintainer of your subsystem tree),
* successfully unit tested, and
* destined for the current or next Linux merge window.

Basically, this should be just what you would send to Linus (or ask him
to fetch). It is allowed to be rebased if you deem it necessary.
