Hi, Investigating the MMU fault corruption issue I found a lot of areas of improvements of the exception handling code.
Moreover, even though the obvious memory corruption is fixed on kernel side, there are still some rare cases where corruption in user-space might be possible if some buffers are still mapped. This came up in a discussion with Fernando Lugo, and we both agreed on a fix (patch #7). The rest is mostly reorganization. (This is basically the same as the old one, but rebased to staging tree) Felipe Contreras (13): staging: ti dspbridge: deh: trivial cleanups staging: ti dspbridge: mmufault: trivial cleanups staging: ti dspbridge: deh: free dummy page immediately staging: ti dspbridge: remove unused code staging: ti dspbridge: mmu: add hw_mmu_tlb_flush_all() staging: ti dspbridge: deh: ensure only tlb #0 is enabled staging: ti dspbridge: deh: refactor in mmu_fault_print_stack() staging: ti dspbridge: deh: remove get_info staging: ti dspbridge: deh: remove err_info staging: ti dspbridge: access deh directly staging: ti dspbridge: move mmufault to deh staging: ti dspbridge: deh: tidying up staging: ti dspbridge: deh: update copyright notice drivers/staging/tidspbridge/Makefile | 2 +- drivers/staging/tidspbridge/core/_deh.h | 2 +- drivers/staging/tidspbridge/core/_tiomap.h | 6 +- drivers/staging/tidspbridge/core/mmu_fault.c | 139 -------- drivers/staging/tidspbridge/core/mmu_fault.h | 36 -- drivers/staging/tidspbridge/core/tiomap3430.c | 17 +- drivers/staging/tidspbridge/core/ue_deh.c | 336 +++++++++----------- drivers/staging/tidspbridge/hw/hw_mmu.c | 6 + drivers/staging/tidspbridge/hw/hw_mmu.h | 2 + .../staging/tidspbridge/include/dspbridge/dbdefs.h | 1 - .../tidspbridge/include/dspbridge/dspdefs.h | 75 ----- .../staging/tidspbridge/include/dspbridge/dspdeh.h | 20 +- drivers/staging/tidspbridge/pmgr/dev.c | 17 +- drivers/staging/tidspbridge/rmgr/node.c | 5 +- drivers/staging/tidspbridge/rmgr/proc.c | 29 +-- 15 files changed, 184 insertions(+), 509 deletions(-) delete mode 100644 drivers/staging/tidspbridge/core/mmu_fault.c delete mode 100644 drivers/staging/tidspbridge/core/mmu_fault.h -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
