2019-01-22mips: mm: no need to check return value of debugfs_create functionsGreg Kroah-Hartman
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

2017-11-03Update MIPS email addressesPaul Burton
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.

2016-08-01MIPS: Modify error handlingAmitoj Kaur Chawla
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 <amitoj1606@gmail.com> 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 <ralf@linux-mips.org>
2015-10-26MIPS: Allow L2 prefetch to be configured via debugfsPaul Burton
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 <paul.burton@imgtec.com> Cc: Maciej W.
