a7fd58c4db Squashed commit of the following: 
many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

b3f0aab00a Squashed commit of the following: 
sched/wqueue/kwork_notifier.c:  Redesign some data structures.  struct works_s must appear at the beginning of the notifier entry structure.  That is because it contains the work queue indices.  This solves a harfault issue.

    net/tcp/tcp_netpoll.c:  tcp_iob_work() needs to free the allocated argument when it is finished.

    net/tcp/tcp_send_buffered.c:  Extend psock_tcp_cansend() so that it also requires that at least on IOB is also avaialble.

    mm/iob:  iob_navail() was returning the number of free IOB chain queue entries, not the number of free IOBs.  Completely misnamed.

    net/tcp/tcp_netpoll.c:  Add logic to receive notifications when IOBs are freed (Needs CONFIG_NET_TCP_WRITE_BUFFERS and CONFIG_IOB_NOTIFIER).  At present, does nothing because the logic in in psock_tcp_cansend() does not check for the availability of IOBs.  That will change.

kinetis:i2c On faild reset re-init i2c and clocking

If a reset fails, we still must reinitializes the
  i2c block so that subsequent transfers will not
  cause a hardfault due to the clock being off.
  If that transfer fails it can try to reset
  again.

91aa26774b This patch prevent heap corruption as in below case. 
TASK A                        TASK B
                              malloc()
                              mm_takesemaphore()
                              heap holder is set to TASK B
                         <--- preempt
...
task_exit()
Set to current task to
  TASK B
Try to release tcb, and
  stack memory
free()
mm_takesemaphore()
  - Successfully obtain
    semaphore because current
    task and heap holder is
    same.
Free memory....
Heap corrupt.

This change forces all de-allocations via sched_kfree() and sched_ufree()
to be delayed.  Eliminating the immediate de-allocation prevents the
above problem with the the re-entrant semaphore because the deallocation
always occurs on the worker thread, never on TASK B.

There could be consequences in the timing of memory availability.  We
will see.

4cb61bd8c2 sched/wqueue: Notifier design cleanup. The original concept used pre-allocated notification data structures. However, the notification dat must persist for an indeterminate amount of time. So the design was modified to use dynamically allocted data structures. This commit simplifies the design by removed some residual 'machinery' that is no longer needed. 2018-09-10 06:29:51 -06:00

arch/arm/src/lpc43xx: Fix ethernet TX_EN pin definitions

TX_EN on LPC43xx can be routed via P0.1 and PC.4 in both
MII and RMII mode.

Before, P0.1 was hardcoded for MII and PC.4 was hardcoded for RMII.

Also, the definitions used inconsistent naming (TXEN vs. TX_EN).
