Laszlo Ersek f98f5ec304 UefiCpuPkg: S3Resume2Pei: align return stacks explicitly 
S3RestoreConfig2() can optionally stack-switch to the SMM S3 Resume Entry
Point and ask it to transfer to S3ResumeExecuteBootScript().

Similarly, S3ResumeExecuteBootScript() stack-switches explicitly to the
boot script executor, and asks it to transfer to S3ResumeBootOs().

Currently the stack pointers specified for the SMM S3 Resume Entry Point
and the boot script executor to use for returning are derived from
addresses of the first local variables in S3RestoreConfig2() and
S3ResumeExecuteBootScript(), respectively.

Since (theoretically) the stack grows down as local variables are defined
and functions are called, the idea is presumably to allow the respective
callee to overwrite the caller's local variables. (The callees in
question can never return normally, only by explicit stack switching.)

Taking the address of "Status" is less portable than optimal however.
Compilers are free to juggle local variables at build time as they
please, including order and alignment on the stack. For example, when the
code is built for 64-bit PEI with gcc-4.8.2, the address of "Status"
trips up the alignment assertion in SwitchStack().

Let's align the address of "Status" down to CPU_STACK_ALIGNMENT
explicitly. If a compiler ensures such alignment and places "Status" at
the highest address automatically, then this change has no effect.
Otherwise, we'll prepare ReturnStackPointer values that (a) are correctly
aligned, (b) preserve the same amount or more (but never less) from the
caller's local variables than before, which should be safe.

Jordan Justen a63f2e2450 UefiCpuPkg/ResetVector/Vtf0: Move Page Table/CR3 setting to a new file 
Now, Transition32FlatTo64Flat calls SetCr3ForPageTables64
which is located in Ia32/PageTables64.asm.

This change is required so OVMF can replace the code in
Ia32/PageTables64.asm with code that generates page tables in
RAM.

Note: Since this change does not impact the functionality of the
current VTF0 binaries, they are not being updated. The resulting
new binaries were tested to verify there is no regression.

jljusten 557b970a2f UefiCpuPkg CpuDxe: Fix bug with CPU Arch RegisterInterruptHandler 
The change in r10765 introduced an issue where inherited interrupt
handlers would override the driver's RegisterInterruptHandler
functionality.

DUET installs a IDT with 256 entries early in it's boot.  Therefore,
no interrupt handlers could be installed with DUET while using
UefiCpuPkg/CpuDxe (instead of DuetPkg/CpuDxe).

This change forces the IDT to be modified when RegisterInterruptHandler
is called to ensure the UEFI handler will be installed properly.
