Subject2.5.5-dj2 compile failures
First the good news - it built the ALSA modules correctly this time around.

And I suspect these are trivial fixes:
USB storage fails by trying to reference "address" member of a
scatterlist, which has a vdma_address (MIPS) or a dma_address (x86)
(didn't check others).
USB Mass Storage is modular, all sub drivers selected.

This affects datafab.c and jumpshot.c.

Some FSs seem to have trouble with dparent_lock - fatfs.o, at least,
caused depmod to say "undefined symbol."
I believe the following patch fixes it.

/* Right now the dcache depends on the kernel lock */
#define check_lock() if (!kernel_locked()) BUG()
