[MTD] physmap.c: Add support for multiple resources
This patch extends the physmap mapping driver to support multiple
resources for non-identical NOR chips that will be concatenated together
when selected.
This is needed for example for Intel 48F4400 512MBit chips, since they
consist of 2 single different NOR chips with different geometries. The
first (lower) one has botton boot sectors and the 2nd (upper) has top
boot sectors. This currently isn't handled correctly by calling the
physmap driver once with only one resource covering both chips in one
memory region. The same geometrie is used for both chips.
With this patch the following resource structure can be used to
describe the 48F4400 chip correctly:
static struct resource board_nor_resource[] = {
[0] = {
.start = 0xf8000000,
.end = 0xfbffffff,
.flags = IORESOURCE_MEM,
},
[1] = {
.start = 0xfc000000,
.end = 0xffffffff,
.flags = IORESOURCE_MEM,
}
};

[MTD] Unlocking all Intel flash that is locked on power up.
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

fix writev regression: pan hanging unkillable and un-straceable
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).
