[edk2-devel] [PATCH v1 1/2] ArmPkg/Drivers/CpuDxe: Explicitly cast table entry

["Michael Kubacki" <mikuback@linux.microsoft.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

GetNextEntryAttribute() assigns a 64-bit integer to 32-bit integers.

This change explicitly casts the assigned value as UINT32 to prevent
the following Visual Studio compiler warning:

  '=': conversion from 'UINT64' to 'UINT32', possible loss of data
