Summary:                    [patch] ztdynamic unable to support large numbers of
channels
Description: 
The use of kmalloc in allocating z->chans (ztdynamic.c:559) prevents the
allocation of large numbers of channels. This is a major bug because even
96 channels (one 4-span T1 card) cannot be supported. The fix is to replace
kmalloc and kfree calls with vmalloc and vfree. A patch is attached.
