EDAC: Raise the maximum number of memory controllers
[ Upstream commit 6b58859419554fb824e09cfdd73151a195473cbc ]
We observe an oops in the skx_edac module during boot:
EDAC MC0: Giving out device to module skx_edac controller Skylake Socket#0 IMC#0
EDAC MC1: Giving out device to module skx_edac controller Skylake Socket#0 IMC#1
EDAC MC2: Giving out device to module skx_edac controller Skylake Socket#1 IMC#0
...
EDAC MC13: Giving out device to module skx_edac controller Skylake Socket#0 IMC#1
EDAC MC14: Giving out device to module skx_edac controller Skylake Socket#1 IMC#0
EDAC MC15: Giving out device to module skx_edac controller Skylake Socket#1 IMC#1
Too many memory controllers: 16
EDAC MC: Removed device 0 for skx_edac Skylake Socket#0 IMC#0
We observe there are two memory controllers per socket, with a limit
of 16. Raise the maximum number of memory controllers from 16 to 2 *
MAX_NUMNODES (1024).
[ bp: This is just a band-aid fix until we've sorted out the whole issue
with the bus_type association and handling in EDAC and can get rid of
this arbitrary limit. ]
