Subject: squashfs: fix breakage when pagesize > blocksize
From: Doug Chapman <doug.chapman@xxxxxx>
Squashfs is broken on any system where the pageszie is larger than either
the block size of the squashfs image or larger than the metadata size
(8192). This is easily fixed by ensuring cache->pages is always > 0.
