Subject[PATCHv2 1/2] x86/MCE/AMD: Export smca_get_bank_type symbol
Date
Export smca_get_bank_type for use in the AMD GPU
driver to determine MCA bank while handling correctable
and uncorrectable errors in GPU UMC.

v1->v2:
- Drop the function is_smca_umc_v2().
- Drop the patch to introduce a new MCE priority (MCE_PRIO_ACEL)
for GPU/accelarator cards.
