TRIG_ROUND_NEAREST is 0, so a bit-and with it is always false.  The
value TRIG_ROUND_MASK covers the bits of the TRIG_ROUND constants, so
first pick those bits and then make the test using ==.

The same is done for TRIG_ROUND_UP for symmetry, even though bit-and would
be sufficient in this case.

This code is used by some combination of the CONFIG_COMEDI_DAS08_CS,
CONFIG_COMEDI_DAS08_ISA, and CONFIG_COMEDI_DAS08_PCI and contains a lot
of conditional compilation.

Remove most of the conditional compilation, relying on the compiler to
optimize out unused static functions and data.  Use the '__maybe_unused'
tag for those functions that cause compiler warnings as a result of
this.

Also change the DO_COMEDI_DRIVER_REGISTER macro from a conditionally
defined macro to a manifest constant macro to allow it to be tested
outside the preprocessor (although this is not currently needed).

xvmalloc can't handle PAGE_SIZE page so that zram have to
handle it specially but zsmalloc can do it so let's remove
unnecessary special handling code.

Quote from Nitin
"I think page vs handle distinction was added since xvmalloc could not
handle full page allocation. Now that zsmalloc allows full page
allocation, we can just use it for both cases. This would also allow
removing the ZRAM_UNCOMPRESSED flag. The only downside will be slightly
slower code path for full page allocation but this event is anyways
supposed to be rare, so should be fine."

1. This patch reduces code very much.

2. change pages_expand with bad_compress so it can count
   bad compression(above 75%) ratio.

3. remove zobj_header which is for back-reference for defragmentation
   because firstly, it's not used at the moment and zsmalloc can't handle
   bigger size than PAGE_SIZE so zram can't do it any more without redesign.

fd1a30de makes a bug that it uses (struct page *) as zsmalloc's handle
although it's a uncompressed page so that it can access random page,
return random data or even crashed by get_first_page in zs_map_object.

We should use unsigned long as handle instead of void * to avoid any
confusion. Without this, users may just treat zs_malloc return value as
a pointer and try to deference it.

This patch passed compile test(zram, zcache and ramster) and zram is
tested on qemu.

These two places seem like they should be using bitwise OR instead of
bitwise AND.  The first one is a noop which is equivalent to:

	imr |= (0x0100 & 0x0004 & 0x0001);

The second is sets lcr2 to zero instead of just clearing the high bits.

	lcr2 &= (0x00F0 & 0x000F);
