[PATCH 0/3] x86: stack alignment for boot code and clang

From: Matthias Kaehlcke
Date: Mon Jun 12 2017 - 20:56:06 EST


This series fixes an issue with the stack of the x86 boot code not
being aligned as intended. Further it adapts the Makefile to account
for the fact that clang uses a different option to configure the
stack alignment than gcc (-mstack-alignment=N vs
-mpreferred-stack-boundary=N)

Matthias Kaehlcke (3):
kbuild: Add cc-option-no-kbuild macro
x86/build: Use cc-option-no-kbuild for boot code compiler options
x86/build: Specify stack alignment for clang
