arch: remove frv port

2018-03-09T22:19:58+00:00

The Fujitsu FRV kernel port has been around for a long time, but has not seen regular updates in several years and instead was marked 'Orphaned' in 2016 by long-time maintainer David Howells. The SoC product line apparently is apparently still around in the form of the Socionext Milbeaut image processor, but this one no longer uses the FRV CPU cores. This removes all FRV specific files from the kernel. Link: http://www.socionext.com/en/products/assp/milbeaut/ Cc: David Howells Signed-off-by: Arnd Bergmann

arch: remove unused macro/function thread_saved_pc()

2017-06-28T23:13:57+00:00

The only user of thread_saved_pc() in non-arch-specific code was removed in commit 8243d5597793 ("sched/core: Remove pointless printout in sched_show_task()"). Remove the implementations as well. Some architectures use thread_saved_pc() in their arch-specific code. Leave their thread_saved_pc() intact.

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:36+00:00

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

Replace with globally

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

FRV: Fix the new-style kernel_thread() stuff

2012-11-02T13:20:43+00:00

The kernel_thread() changes for FRV don't work, and FRV fails to boot, starting with: commit 02ce496f152df87be081a64796498942c433a2fd Author: Al Viro Date: Tue Sep 18 22:18:51 2012 -0400 Subject: frv: split ret_from_fork, simplify kernel_thread() a lot The problem is that the userspace registers are completely cleared when a kernel thread is created and all subsequent user threads are then copied from that. Unfortunately, however, the TBR and PSR registers are restored from the pt_regs and the values they should be set to are clobbered by the memset. Instead, copy across the old user registers as normal, and then merely alter GR8 and GR9 in it if we're going to execute a kernel thread. Signed-off-by: David Howells
