2014-01-22Check null pointers for sysfs callsStefan Agner
When grepping through sysfs, grep tries to read all sysfs files which are available. Some of them lead to error due to null pointers. Therefor check for null pointers before using them.

This adds an ADC driver for the STMPE device using the industrial input/output interface. The driver supports raw reading of values. The driver depends on the MFD stmpe driver. If the touchscreen block is enabled too, only for of the 8 ADC channels are available.

2012-07-24android: logger: Allow a UID to read it's own log entriesNick Kralevich
Modify the kernel logger to record the UID associated with the log entries. Always allow the same UID which generated a log message to read the log message. Allow anyone in the logs group, or anyone with CAP_SYSLOG, to read all log entries. In addition, allow the client to upgrade log formats, so they can get additional information from the kernel.

2011-11-30lowmemorykiller: don't unregister notifier from atomic contextRabin Vincent
The lowmemorykiller registers an atomic notifier for notfication of when the task is freed. From this atomic notifier callback, it removes the atomic notifier via task_free_unregister(). This is incorrect because atomic_notifier_chain_unregister() calls syncronize_rcu(), which can sleep, which shouldn't be done from an atomic notifier. Fix this by registering the notifier during init, and only unregister it if the lowmemorykiller is unloaded.

2011-11-30binder: Fix memory corruption via page aliasingChristopher Lais
binder_deferred_release was not unmapping the page from the buffer before freeing it, causing memory corruption. This only happened when page(s) had not been freed by binder_update_page_range, which properly unmaps the pages. This only happens on architectures with VIPT aliasing. To reproduce, create a program which opens, mmaps, munmaps, then closes the binder very quickly. This should leave a page allocated when the binder is released. When binder_deferrred_release is called on the close, the page will remain mapped to the address in the linear proc->buffer. Later, we may map the same physical page to a different virtual address that has different coloring, and this may cause aliasing to occur. PAGE_POISONING will greatly increase your chances of noticing any problems. Change-Id: I6941bf212881b8bf846bdfda43d3609c7ae4892e Signed-off-by: Christopher Lais <chris+android@zenthought.org>

2011-11-30lowmemorykiller: Don't try to kill the same pid over and overSan Mehat
Under certain circumstances, a process can take awhile to handle a sig-kill (especially if it's in a scheduler group with a very low share ratio). When this occurs, lowmemkiller returns to vmscan indicating the process memory has been freed - even though the process is still waiting to die. Since the memory hasn't actually freed, lowmemkiller is called again shortly after, and picks the same process to die; regardless of the fact that it has already been 'scheduled' to die and the memory has already been reported to vmscan as having been freed. Solution is to check fatal_signal_pending() on the selected task, and if it's already pending destruction return; indicating to vmscan that no resources were freed on this pass.
