Ard Biesheuvel 91231b55d5 ArmPlatformPkg/ArmPlatformStackLib: use callee preserved registers ... The entry code in ArmPlatformStackSet () is a 1:1 transliteration of the ARM version, which uses the callee preserved registers r3 - r7 (*) to preserve the function arguments and the link register across a call to ArmPlatformIsPrimaryCore (). However, x3 - x7 are not callee preserved on AARCH64, and so we should use registers >= x19 instead. While we're at it, drop an unnecessary preserve of the link register, and simplify/deobfuscate the calculation of the secondary stack position. (*) Note that r3 is not actually a callee saved register even on ARM.
