| 2019-01-22 | mips: kernel: no need to check return value of debugfs_create functions | Greg Kroah-Hartman | 1 | -12/+3 | |
| 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.

| 2016-07-28 | MIPS: Print segment physical address when EU=1 | James Hogan | 1 | -5/+8 | |
| Currently the debugfs interface to print the segment configuration refuses to print the physical address of mapped segments. However if the EU bit is set these become unmapped at error level (when CP0_Status.ERL=1), so the physical address is still relevant. Update the logic to print the physical address of mapped segments when the EU bit is set, while still hiding the Cache Coherency Attribute (since EU overrides that to uncached when ERL=1 too).

| 2015-10-26 | MIPS: Declare mips_debugfs_dir in a header | Paul Burton | 1 | -1/+1 | |
| We have many extern declarations of mips_debugfs_dir through arch/mips/ in various C files. Unify them by declaring mips_debugfs_dir in a header, including it in each affected C file & removing the duplicate declarations.
