* More fixes to problems noted by cppcheck. Some are kind of risky; some are ↵Gregory Nutt2014-11-252-3/+3
| | | | real bugs.
* If the INTR granule allocator mode is enabled, there is noGregory Nutt2014-11-121-0/+2
| | | | semaphore to destroy. From Lorenz Meier.
* Fix a typo in a Kconfig fileGregory Nutt2014-09-271-1/+1

* Move include/nuttx/gran.h to include/nuttx/mm/gran.hGregory Nutt2014-09-2411-11/+11
|
* Completes the implemenation of the core shared memory logic: shmget(), ↵Gregory Nutt2014-09-232-21/+223
| | | | shmctl(), shmat(), and shmdt(). This is still some unfinish platform-specific code that needs to be done before we can begin testing.
* Remove executable modeGregory Nutt2014-09-233-0/+0
|
* Add interfaces to support un-initializing a granule allocator.Gregory Nutt2014-09-231-2/+2
|
* Add support for a per-process virtual page allocator. This is a new member ↵Gregory Nutt2014-09-231-0/+69
| | | | of the task_group_s structure. The allocaor must be initialized when a new user process is started and uninitialize when the process group is finally destroyed. It is used by shmat() and shmdt() to pick the virtual address onto which to map the shared physical memory.

* Restructuring of build to allow use of use-space allocators by kernel logic ↵Gregory Nutt2014-09-022-4/+6

* Space at the beginning of the process data space is now reserved for user ↵Gregory Nutt2014-09-0213-62/+243
