Update MIPS email addresses

2017-11-03T16:02:30+00:00

MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.

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.

MIPS: Modify error handling

2016-08-01T20:54:48+00:00

debugfs_create_file returns NULL on error so an IS_ERR test is incorrect here and a NULL check is required. The Coccinelle semantic patch used to make this change is as follows: @@ expression e; @@ e = debugfs_create_file(...); if( - IS_ERR(e) + !e ) { <+... return - PTR_ERR(e) + -ENOMEM ; ...+> } Signed-off-by: Amitoj Kaur Chawla Cc: julia.lawall@lip6.fr Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/13834/ Signed-off-by: Ralf Baechle

MIPS: Allow L2 prefetch to be configured via debugfs

2015-10-26T08:49:42+00:00

When debugging or examining the performance of a system it can be useful to examine the effect of L2 prefetching. Provide an optional debugfs entry to allow a user to enable or disable L2 prefetching. Signed-off-by: Paul Burton Cc: Maciej W.
