Hi, I need to compile my own kernels to carry out some tests on Replicant devices to document the issues with USB WiFi on them.
So while at it, I did a HOWTO since Tiberiu-Cezar was interested in the same thing. I had to do some minor patching to make crespo kernel compile. The patches are attached and will be sent to gitlab once I get an account. Denis.

Subject: [PATCH 1/3] gpu: pvr: Fix compilation with gcc 4.8.2
Without that fix, with gcc 4.8.2 we have:
drivers/gpu/pvr/sgx/mmu.c: In function 'MMU_Alloc':
drivers/gpu/pvr/sgx/mmu.c:1176:11: error: 'sDevPAddr.uiAddr' may be used uninitialized in this function [-Werror=maybe-uninitialized]
| SGX_MMU_PDE_VALID;
^
drivers/gpu/pvr/sgx/mmu.c:1116:20: note: 'sDevPAddr.uiAddr' was declared here
IMG_DEV_PHYADDR sDevPAddr;
^
