Subject: [PATCH v2 0/8] clean up vdso-layout.lds.S

The handling of various sections in the VDSO linker script
looks pretty haphazard. This patch series cleans it up in
these regards:

 - improve the coding style
 - remove superfluous sections
 - issue a linker error if a section is encountered which
   is known not to work
 - check that the .got section is empty, except for the
   three entries defined by the ABI
 - discard sections which are not useful to user-space

Petr Tesarik (8):
  x86: Adjust the coding style of vdso-layout.lds.S
  x86: Remove .sdata from the vDSO linker script
  x86: Remove .dynbss from the vDSO linker script
  x86: add .broken section to the vDSO linker script
  x86: mark altinstr-related sections in vDSO as broken
  x86: mark some standard sections as broken in a vDSO
  x86: check the size of GOT in vDSO
  x86: remove unneeded section from the vDSO
