Hi Ingo, I saw you picked up Arvind's other series into x86/boot. Would you mind please including this, as well? Our CI is quite red for x86... EOM On Sat, Aug 15, 2020 at 8:49 AM Sedat Dilek wrote: > > On Wed, Aug 12, 2020 at 2:43 AM Arvind Sankar wrote: > > > > The x86-64 psABI [0]

[PATCH v2] x86/boot/compressed: Disable relocation relaxation

2020-08-11 Thread Arvind Sankar
The x86-64 psABI [0] specifies special relocation types (R_X86_64_[REX_]GOTPCRELX) for indirection through the Global Offset Table, semantically equivalent to R_X86_64_GOTPCREL, which the linker can take advantage of for optimization (relaxation) at link time. This is supported by LLD and binutils
