Patch for unlocking all Intel flash that has instant locking on power up. The patch has been tested on Intel M18, P30 and J3D Strata Flash. 1. The automatic unlocking can be disabled for a particular partition in the map or the command line. a. For the bit mask in the map it should look like: .mask_flags = MTD_POWERUP_LOCK, b. For the command line parsing it should look like: mtdparts=0x80000(bootloader)lk 2. This will only unlock parts with instant individual block locking. Intel parts with legacy unlocking will not be unlocked. Signed-off-by:Justin Treon <justin_treon@yahoo.com> Signed-off-by:

Frederik Himpe reported an unkillable and un-straceable pan process. Zero length iovecs can go into an infinite loop in writev, because the iovec iterator does not always advance over them. The sequence required to trigger this is not trivial. I think it requires that a zero-length iovec be followed by a non-zero-length iovec which causes a pagefault in the atomic usercopy. This causes the writev code to drop back into single-segment copy mode, which then tries to copy the 0 bytes of the zero-length iovec; a zero length copy looks like a failure though, so it loops. Put a test into iov_iter_advance to catch zero-length iovecs. We could just put the test in the fallback path, but I feel it is more robust to skip over zero-length iovecs throughout the code (iovec iterator may be used in filesystems too, so it should be robust).

All those 2-byte values denoting the different capabilities are being written to the local copy of the caps buffer without being converted to big endian for simplicity of usage and shorter code later. Also, we add some comments stating which are the fields of the caps page in question in order to alleviate the cryptic pointer casting exercises as in e.g. idetape_get_mode_sense_results(). There should be no functional changes resulting from this patch. Bart: - remove two needless "!!" Signed-off-by:
