This patch switches zcache and zram dependency to ZSMALLOC rather than X86. There is no net change since ZSMALLOC depends on X86, however, this prevent further changes to these files as zsmalloc dependencies change.

Pages written to these disks are compressed and stored in memory
|
|

It has several use cases, for example: /tmp storage, use as swap
|
|
disks and maybe many more.
