      arm64: vdso: use $(LD) instead of $(CC) to link VDSO · 691efbed
      Masahiro Yamada authored
      We use $(LD) to link vmlinux, modules, decompressors, etc.
      
      VDSO is the only exceptional case where $(CC) is used as the linker
      driver, but I do not know why we need to do so. VDSO uses a special
      linker script, and does not link standard libraries at all.
      
      I changed the Makefile to use $(LD) rather than $(CC). I tested this,
      and VDSO worked for me.
      
      Users will be able to use their favorite linker (e.g. lld instead of
      of bfd) by passing LD= from the command line.
      
      My plan is to rewrite all VDSO Makefiles to use $(LD), then delete
      cc-ldoption.

      arm64: compat: Reduce address limit · d2631193
      Vincenzo Frascino authored
      Currently, compat tasks running on arm64 can allocate memory up to
      TASK_SIZE_32 (UL(0x100000000)).
      
      This means that mmap() allocations, if we treat them as returning an
      array, are not compliant with the sections 6.5.8 of the C standard
      (C99) which states that: "If the expression P points to an element of
      an array object and the expression Q points to the last element of the
      same array object, the pointer expression Q+1 compares greater than P".
      
      Redefine TASK_SIZE_32 to address the issue.
