commit f90c4fff00bee5f654ad93afd0f74b99050960de
Author: Hao Wu <hao.a.wu@xxxxxxxxx>

    IntelFrameworkModulePkg/IdeBusDxe: Fix undefined behavior in signed left 
shift
    
    In function AtapiReadCapacity(), the following expression:
    IdeDev->BlkIo.Media->LastBlock = (Data.LastLba3 << 24) |
      (Data.LastLba2 << 16) |
      (Data.LastLba1 << 8) |
      Data.LastLba0;
    
    (There is also a similar case in this function.)
    
    will involve undefined behavior in signed left shift operations.
    
    Since Data.LastLbaX is of type UINT8, and
    IdeDev->BlkIo.Media->LastBlock is of type UINT64. Therefore,
    Data.LastLbaX will be promoted to int (32 bits, signed) first,
    and then perform the left shift operation.
    
    According to the C11 spec, Section 6.5.7:
    4 The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated
      bits are filled with zeros. If E1 has an unsigned type, the value
      of the result is E1 * 2^E2 , reduced modulo one more than the
      maximum value representable in the result type. If E1 has a signed
      type and nonnegative value, and E1 * 2^E2 is representable in the
      result type, then that is the resulting value; otherwise, the
      behavior is undefined.
    
    So if bit 7 of Data.LastLba3 is 1, (Data.LastLba3 << 24) will be out of
    the range within int type. The undefined behavior of the signed left shift
    will lead to a potential of setting the high 32 bits of
    IdeDev->BlkIo.Media->LastBlock to 1 during the cast from type int to type
    UINT64.
    
    This commit will add an explicit UINT32 type cast for Data.LastLba3 to
    resolve this issue.

    (There is also a similar case in function PeiUsbReadFormattedCapacity().)
    
    will involve undefined behavior in signed left shift operations.
    
    Since Data.LastLbaX is of type UINT8, they will be promoted to int (32
    bits, signed) first, and then perform the left shift operation.
