[PATCH] silence unused pgdat warning from alloc_bootmem_node and friends
x86 NUMA systems only define bootmem for node 0. alloc_bootmem_node() and
friends therefore ignore the passed pgdat and use NODE_DATA(0) in all
cases. This leads to the following warnings as we are not using the passed
parameter:
.../mm/page_alloc.c: In function 'zone_wait_table_init':
.../mm/page_alloc.c:2259: warning: unused variable 'pgdat'
One option would be to define all variables used with these macros
__attribute__ ((unused)), but this would leave us exposed should these
become genuinely unused.
The key here is that we _are_ using the value, we ignore it but that is a
deliberate action. This patch adds a nested local variable within the
alloc_bootmem_node helper to which the pgdat parameter is assigned making
it 'used'. The nested local is marked __attribute__ ((unused)) to silence
this same warning for it.
