Simple fix is below.
But things still aren't very good.
initramfs-support-initramfs-that-is-more-than-2g.patch switches
avail_in and avail_out from uint to ulong but failed to fix up a whole
bunch of code which expects to handle 32-bit quantities.
eg:
static int zlib_compress_update(struct crypto_pcomp *tfm,
struct comp_request *req)
{
int ret;
...
ret = req->avail_out - stream->avail_out;
This is at least sloppy and is quite possibly buggy.
