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. These apply on top of the MMU fault fix patch.
