Hello all,
I'm not sure if this is the correct place to post this. Please let me know.
I am seeing a lot of sparse warnings when compiling the linux kernel that look like this:
arch/x86/kernel/cpu/mcheck/mce_intel.c:25:8: warning: symbol 'mce_banks_owned' was not declared. Should it be static?
This line in the code is:
static DEFINE_PER_CPU(mce_banks_t, mce_banks_owned);
I'm not really sure what the DEFINE_PER_CPU macro expands to so I'm not sure if the 'static' in front is actually getting used or if sparse is just confused.
Is this an actual problem in the linux kernel or is sparse just getting tripped up by the DEFINE_PER_CPU macro?
Thanks, Hartley
