I wouldn'tYes patch created against stock code .bless it as an alternative because it moves code and comments unnecessarily - all you should really have to do is to move the 190 mfc0 v1, CP0_STATUS 191 LONG_S $2, PT_R2(sp) to be just after the #endif /* CONFIG_MIPS_MT_SMTC */ at around line 201.Actually I just moved code under CONFIG_MIPS_MT_SMTC to previous block of code ( which store $0 ) . git diff did the rest on behalf of me :)If moving the save of zero to PT_R0(sp) actually makes a difference, it's evidence that you've got problems in your toolchain (or, heaven forbid, your pipeline)!In previous version of patch usage of V0 was creating issue. I have verified this with previous version of code ( working code before David's instruction rearrangement patch.) .
Argh. It's not very clearly commented, but it looks as if the system call trap handler has an implicit assumption that v0 has never been changed by SAVE_SOME, TRACE_IRQS_ON_RELOAD, or STI. So yeah, moving the code around to fix the v1 conflict ends up being better than using v0 - otherwise, we'd need to add a LONG_L v0, PT_R2(sp) somewhere after the LONG_S v0, PT_TCSTATUS(sp) of the original patch.
