2015-04-30MdePkg/BaseLib: Preserve EBX register and fix stack offset to LinearAddress ↵Michael Kinney
in AsmFlushCacheLine() The value of EBX must be preserved to follow IA32 cdecl calling convention in the assembly implementation of AsmFlushCacheLine(). The CPUID instruction modifies the EBX register. The EBX register value is saved onto the stack before CPUID and restored from the stack after CPUID. The update to the inline assembly implementation of AsmFlushCacheLine() changed the location of the LinearAddress parameter value on the stack. The hardcoded lookup using [esp + 4] is not correct. Use the parameter name LinearAddress instead of the hard coded [esp + 4] stack location to prevent this issue from occurring again if there are changes to the inline assembly in the future.

2014-09-01MdePkg BaseLib NASM Thunk16: Initialize _16GdtrBase to 0Jordan Justen
Previously we were setting it to the start of the GDT in the UEFI driver's copy of BaseLib. This address is irrelavent, since the C code will initialize it to the cooresponding address after the Thunk16 code has been placed in low memory. Additionally, initializing this was causing a link error for the XCLANG toolchain.
