      [JFFS2] Fix printk format in some error messages. · 184f5652
      由 Andrew Morton 提交于 
      fs/jffs2/nodelist.c: In function `check_node_data':
fs/jffs2/nodelist.c:441: warning: unsigned int format, different type arg (arg 4)
fs/jffs2/nodelist.c:464: warning: int format, different type arg (arg 5)

Modified from Andrew's original fix because while his terminal may indeed
only have eighty columns, mine only has _TWENTYFOUR_ lines. So the
cosmetic fluff is perfectly OK out past column 80 where it was -- the
casual reader doesn't _care_ about anything more than the fact that it
goes 'if (foo) JFFS2_WARNING...', and there's no point wasting a whole
line to display the tail end of the printk which nobody actually cares
about.

      [JFFS2] Don't pack on-medium structures, because GCC emits crappy code · 3e68fbb5
      由 David Woodhouse 提交于 
      If we use __attribute__((packed)), GCC will _also_ assume that the
structures aren't sensibly aligned, and it'll emit code to cope with
that instead of straight word load/save. This can be _very_ suboptimal
on architectures like ARM.

Ideally, we want an attribute which just tells GCC not to do any
padding, without the alignment side-effects. In the absense of that,
we'll just drop the 'packed' attribute and hope that everything stays as
it was (which to be fair is fairly much what we expect). And add some
paranoia checks in the initialisation code, which should be optimised
away completely in the normal case.

      [MTD] Convert physmap to platform driver · 73566edf
      由 Lennert Buytenhek 提交于 
      After dwmw2 let me know it ought to be done, I rewrote the physmap map
driver to be a platform driver.  I know zilch about the driver model,
so I probably botched it in some way, but I've done some tests on an
ixp23xx board which uses physmap, and it all seems to work.

In order to not break existing physmap users, I've added some compat
code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN
is defined and != 0.  Also, I've changed the default value for
CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently
compile in physmap (or new, platform-style, users of physmap) don't get
burned.

This works pretty well -- the new physmap driver is a drop-in replacement
for the old one, and works on said ixp23xx board without any code changes
needed.  (This should hold as long as users don't touch 'physmap_map'
directly.)

Once all physmap users have been converted to instantiate their own
platform devices, the compat code can go.  (Or we decide that we can
change all the in-tree users at the same time, and never merge the
compat code.)
