d2: now with valid gpios!

I'm not sure this matters, but this has bothered me since I did the
apexq bring-up. d2 has been importing a Nokia gpio file instead of the
MSM one.

mm: remove compressed copy from zram in-memory

Swap subsystem does lazy swap slot free with expecting the page would be
swapped out again so we can avoid unnecessary write.

But the problem in in-memory swap(ex, zram) is that it consumes memory
space until vm_swap_full(ie, used half of all of swap device) condition
meet.  It could be bad if we use multiple swap device, small in-memory
swap and big storage swap or in-memory swap alone.

This patch makes swap subsystem free swap slot as soon as swap-read is
completed and make the swapcache page dirty so the page should be
written out the swap device to reclaim it.  It means we never lose it.

I tested this patch with kernel compile workload.

1. before

   compile time : 9882.42
   zram max wasted space by fragmentation: 13471881 byte
   memory space consumed by zram: 174227456 byte
   the number of slot free notify: 206684

2. after

   compile time : 9653.90
   zram max wasted space by fragmentation: 11805932 byte
   memory space consumed by zram: 154001408 byte
   the number of slot free notify: 426972

lib/lzo: Update LZO compression to current upstream version

This commit updates the kernel LZO code to the current upsteam version
which features a significant speed improvement - benchmarking the
Calgary
and Silesia test corpora typically shows a doubled performance in
both compression and decompression on modern i386/x86_64/powerpc
machines.

msm: msm_fb: wait for VSYNC instead of DMA_P for commit completion.

In the current implementation, we are waiting for DMA_P interrupt
in commit call to signal completion. This can cause 2 commits happening
in the same vsync period due to which IOMMU page faults can happen when
vsync comes while second commit is programming resgisters. To avoid this,
wait for DMA_P is replaced by wait for VSYNC.
