Muralidhara M K a9b9ea0e63 x86/MCE/AMD: Use an u64 for bank_map 
[ Upstream commit 4c1cdec319b9aadb65737c3eb1f5cb74bd6aa156 ]

Thee maximum number of MCA banks is 64 (MAX_NR_BANKS), see

  a0bc32b3ca ("x86/mce: Increase maximum number of banks to 64").

However, the bank_map which contains a bitfield of which banks to
initialize is of type unsigned int and that overflows when those bit
numbers are >= 32, leading to UBSAN complaining correctly:

  UBSAN: shift-out-of-bounds in arch/x86/kernel/cpu/mce/amd.c:1365:38
  shift exponent 32 is too large for 32-bit type 'int'

Change the bank_map to a u64 and use the proper BIT_ULL() macro when
modifying bits in there.

  [ bp: Rewrite commit message. ]

Fixes: a0bc32b3ca ("x86/mce: Increase maximum number of banks to 64")
