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

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.

commit a0bc32b3ca upstream.
...because future AMD systems will support up to 64 MCA banks per CPU.
MAX_NR_BANKS is used to allocate a number of data structures, and it is
used as a ceiling for values read from MCG_CAP[Count]. Therefore, this
change will have no functional effect on existing systems with 32 or
fewer MCA banks per CPU.
However, this will increase the size of the following structures:
Global bitmaps:
- core.c / mce_banks_ce_disabled
- core.c / all_banks
- core.c / valid_banks
- core.c / toclear
- Total: 32 new bits * 4 bitmaps = 16 new bytes
Per-CPU bitmaps:
- core.c / mce_poll_banks
- intel.c / mce_banks_owned
- Total: 32 new bits * 2 bitmaps = 8 new bytes
The bitmaps are arrays of longs. So this change will only affect 32-bit
execution, since there will be one additional long used. There will be
no additional memory use on 64-bit execution, because the size of long
is 64 bits.
Global structs:
- amd.c / struct smca_bank smca_banks[]: 16 bytes per bank
- core.c / struct mce_bank_dev mce_bank_devs[]: 56 bytes per bank
- Total: 32 new banks * (16 + 56) bytes = 2304 new bytes
Per-CPU structs:
- core.c / struct mce_bank mce_banks_array[]: 16 bytes per bank
- Total: 32 new banks * 16 bytes = 512 new bytes
32-bit
Total global size increase: 2320 bytes
Total per-CPU size increase: 520 bytes
64-bit
Total global size increase: 2304 bytes
Total per-CPU size increase: 512 bytes
This additional memory should still fit within the existing .data
section of the kernel binary. However, in the case where it doesn't
fit, an additional page (4kB) of memory will be added to the binary to
accommodate the extra data which will be the maximum size increase of
vmlinux.
