samples: disable CONFIG_SAMPLES for UML

2018-10-10T17:15:46Z

Some samples require headers installation, so commit 3fca1700c4c3 ("kbuild: make samples really depend on headers_install") added such dependency in the top Makefile. However, UML fails to build with CONFIG_SAMPLES=y because UML does not support headers_install.

arch: remove blackfin port

2018-03-16T09:55:47Z

The Analog Devices Blackfin port was added in 2007 and was rather active for a while, but all work on it has come to a standstill over time, as Analog have changed their product line-up. Aaron Wu confirmed that the architecture port is no longer relevant, and multiple people suggested removing blackfin independently because of some of its oddities like a non-working SMP port, and the amount of duplication between the chip variants, which cause extra work when doing cross-architecture changes.

samples: Introduce Qualcomm QMI sample client

The spawned clients implements the interface for encoding "ping" and "data" requests and decode the responses from the remote. Acked-By: Chris Lew Signed-off-by: Bjorn Andersson

livepatch: introduce shadow variable API

2017-09-14T21:06:12Z

Add exported API for livepatch modules: klp_shadow_get() klp_shadow_alloc() klp_shadow_get_or_alloc() klp_shadow_free() klp_shadow_free_all() that implement "shadow" variables, which allow callers to associate new shadow fields to existing data structures. This is intended to be used by livepatch modules seeking to emulate additions to data structure definitions. See Documentation/livepatch/shadow-vars.txt for a summary of the new shadow variable API, including a few common use cases. See samples/livepatch/livepatch-shadow-* for example modules that demonstrate shadow variables.
