Great work !

some build feedback (trying to do complete x86-64/x86-kvm/x86-generic):
1. Missing configure symbols (since a min. config was built):
- some might be part of package/kernel/linux/modules/*.mk - if the CONFIG symbol is there then its not in generic afaics
Example: DM_MQ_DEFAULT, DM_LOG_WRITES
- some are arch specific (X86_VSYSCALL_EMULATION)

The two points above shouldnt be integrated in this patchset BUT

- some missing symbols appear after module/config selection 
Example: SND_SOC_WM8804_I2C, LIVEPATCH

are missing - I have atm (some of these are missing in 3.18 or 4.0 too - just consult lkddb):

+# CONFIG_CM3323 is not set
+# CONFIG_FB_SM750 is not set

2. any(?) mac80211 does not built

Error: include/net/cfg80211.h:3249:25: error: 'struct wiphy' has no member named '_net'
  return read_pnet(&wiphy->_net);

I did try to use the v4.1-rc1 Backports package as drop-in (only some OpenWrt specific driver series patches were not applied) 
since it should deal with that error, (

but I get compile errors with that too:
include/net/cfg80211.h:3253:2: error: implicit declaration of function 'possible_write_pnet'
include/net/cfg80211.h:3248:2: error: implicit declaration of function 'possible_read_pnet'
(introduced by https://git.kernel.org/cgit/linux/kernel/git/backports/backports.git/tree/patches/collateral-evolutions/network/0053-possible_net_t.patch )

3. Other issues with packages:

- xtables-addons : error: 'BRNF_BRIDGED' undeclared 
possible reason: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=40451fd013878b005ccae767dfebc07dfecf85d9
- batman-adv fails to build
