InitializeCpuExceptionHandlers() expects caller allocates IDT while InitializeCpuInterruptHandlers() allocates 256 IDT entries itself. InitializeCpuExceptionHandlers() fills max 32 IDT entries allocated by caller. If caller allocates 10 entries, the API just fills 10 IDT entries. The inconsistency between the two APIs makes code hard to unerstand and hard to share. Because there is only one caller (CpuDxe) for InitializeCpuInterruptHandler(), this patch updates CpuDxe driver to allocates 256 IDT entries then call InitializeCpuExceptionHandlers(). This is also a backward compatible change. With this change, InitializeCpuInterruptHandlers() is removed completely. And InitializeCpuExceptionHandlers() fills max 32 entries for PEI and SMM instance, max 256 entries for DXE instance. Such behavior matches to the original one.
