* Freezer: Fix buggy resume test for tasks frozen with cgroup freezerMatt Helsley2010-03-263-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the cgroup freezer is used to freeze tasks we do not want to thaw those tasks during resume. Currently we test the cgroup freezer state of the resuming tasks to see if the cgroup is FROZEN. If so then we don't thaw the task. However, the FREEZING state also indicates that the task should remain frozen. This also avoids a problem pointed out by Oren Ladaan: the freezer state transition from FREEZING to FROZEN is updated lazily when userspace reads or writes the freezer.state file in the cgroup filesystem. This means that resume will thaw tasks in cgroups which should be in the FROZEN state if there is no read/write of the freezer.state file to trigger this transition before suspend. NOTE: Another "simple" solution would be to always update the cgroup freezer state during resume. However it's a bad choice for several reasons: Updating the cgroup freezer state is somewhat expensive because it requires walking all the tasks in the cgroup and checking if they are each frozen. Worse, this could easily make resume run in N^2 time where N is the number of tasks in the cgroup. Finally, updating the freezer state from this code path requires trickier locking because of the way locks must be ordered. Instead of updating the freezer state we rely on the fact that lazy updates only manage the transition from FREEZING to FROZEN. We know that a cgroup with the FREEZING state may actually be FROZEN so test for that state too. This makes sense in the resume path even for partially-frozen cgroups -- those that really are FREEZING but not FROZEN.

* Freezer: Only show the state of tasks refusing to freezeXiaotian Feng2010-03-261-2/+1

* NOMMU: Fix __get_user_pages() to pin last page on offset buffersDavid Howells2010-03-251-1/+1
| | | | | | | | | | | | | | Fix __get_user_pages() to make it pin the last page on a buffer that doesn't begin at the start of a page, but is a multiple of PAGE_SIZE in size. The problem is that __get_user_pages() advances the pointer too much when it iterates to the next page if the page it's currently looking at isn't used from the first byte. This can cause the end of a short VMA to be reached prematurely, resulting in the last page being lost. Signed-off-by: Steven J.

| | | | | | | | | | | | | | | | | | | | Revert the following patch: commit c08c6e1f54c85fc299cf9f88cf330d6dd28a9a1d Author: Steven J. Magnani <steve@digidescorp.com> Date: Fri Mar 5 13:42:24 2010 -0800 nommu: get_user_pages(): pin last page on non-page-aligned start As it assumes that the mappings begin at the start of pages - something that isn't necessarily true on NOMMU systems. On NOMMU systems, it is possible for a mapping to only occupy part of the page, and not necessarily touch either end of it; in fact it's also possible for multiple non-overlapping mappings to coexist on one page (consider direct mappings of ROMFS files, for example).

This entire function is guarded with a spin_lock_irqsave at the start of the function and a spin_unlock_irqrestore at the end. As each byte is transferred, the i2c ACK from the DAC is checked. Currently, if the ACK is missing the function simply returns without the unlock. It also leaves the i2c bus in an invalid state since the last byte transferred did not have a "stop" condition and leave the bus idle. Fix this by adding an exit path using goto.

To correctly access these registers LOCOMO_SPI must always be included in the address calculation. There are two places in locomo.c where this is not done. The first one, in locomo_suspend, actually results in a write to LOCOMO_ST instead of LOCOMO_SPICT. The second is in __locomo_probe and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE. Fix these by including LOCOMO_SPI in the calculation. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
