Hi all:
I solved the problem from Steve deRosier's help. And my method as below:
Step 1: linux-next check out to latest version, backports also
checkout to master and apply ccm patch.
Step 2: generate tree by ./gentree.py --verbose --clean ~/linux-next/
~/backports-output
Step 3: modify DECLARE_EWMA(signal, 10, 8) to DECLARE_EWMA(signal,
1024, 8) in ../mac80211/sta_info.h of backports-output
Step 4: modify "skb=idr_remove(...);" to "skb=idr_find(...); if (skb)
idr_remove(...);" in ../mac80211/status.h of backports-output
Step 5: Target linux kernel (the lower version or your specific
version ) need to be compiled first.
Step 6: export KLIB_BUILD="path/to/your_lower_linux_kernel"
Step 7: export KLIB="path/to/your/build/object" (I am about to get
*.ko, thus i point the directory to backports-output)
Step 8: make defconfig-your_choice (I am using defconfig-ath10k)
Step 9: make the backports-output and wait to compile.
My compile environment is Ubuntu16.04 with kernel 4.4 and I am porting
ath10k in linux kernel 4.11 back to linux 4.2.
