frv: Remove signal translation and exec_domain

2015-04-12T18:58:24+00:00

As execution domain support is gone we can remove signal translation from the signal code and remove exec_domain from thread_info. Signed-off-by: Richard Weinberger

all arches, signal: move restart_block to struct task_struct

2015-02-13T02:54:12+00:00

If an attacker can cause a controlled kernel stack overflow, overwriting the restart block is a very juicy exploit target. This is because the restart_block is held in the same memory allocation as the kernel stack. Moving the restart block to struct task_struct prevents this exploit by making the restart_block harder to locate. Note that there are other fields in thread_info that are also easy targets, at least on some architectures. It's also a decent simplification, since the restart code is more or less identical on all architectures.

[PATCH] FRV: Introduce asm-offsets for FRV arch

2006-07-10T20:24:22+00:00

Introduce the use of asm-offsets into the FRV architecture. Signed-off-by: David Howells Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kbuild: frv,m32r,sparc64 introduce fake asm-offsets.h file

Needed to get them to build. And a hint to avoid hardcoding to many constants in assembler. Signed-off-by: Sam Ravnborg
