[PATCH 0/4] pc-bios/s390-ccw: Fixes and improvements for start.S

[Thomas Huth <thuth@redhat.com>]

Main motivation of this series was a bug that showed up when compiling
with Clang 16 and binutils 2.40 (which has been reported in Fedora ELN, see
https://bugzilla.redhat.com/show_bug.cgi?id=2216662). This is fixed in
the fourth patch.

While working on this issue, I came accross some other issues which I
address in the first three patches:

- Indentation is a mixture between tabs and spaces in start.S (patch 1)
- We do not set up a stack frame for the main() function, which could
  cause memory corruption (patch 2)
- The stack is declared in multiple places, though it's only needed
  in start.S (patch 3)

Thomas Huth (4):
  pc-bios/s390-ccw: Fix indentation in start.S
  pc-bios/s390-ccw: Provide space for initial stack frame in start.S
  pc-bios/s390-ccw: Move the stack array into start.S
  pc-bios/s390-ccw: Don't use __bss_start with the "larl" instruction
