      arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0 · 51b563fc
      Sam Ravnborg 提交于
      Albin Tonnerre <albin.tonnerre@free-electrons.com> reported:
      
          Bash 4 filters out variables which contain a dot in them.
          This happends to be the case of CPPFLAGS_vmlinux.lds.
          This is rather unfortunate, as it now causes
          build failures when using SHELL=/bin/bash to compile,
          or when bash happens to be used by make (eg when it's /bin/sh)
      
      Remove the common definition of CPPFLAGS_vmlinux.lds by
      pushing relevant stuff to either Makefile.build or the
      arch specific kernel/Makefile where we build the linker script.
      
      This is also nice cleanup as we move the information out where
      it is used.
      
      Notes for the different architectures touched:
      
      arm - we use an already exported symbol
      cris - we use a config symbol aleady available
             [Not build tested]
      mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
             Added a few variables to CPPFLAGS - they are only used by
             the linker script.
             [Not build tested]
      powerpc - removed assignment that is not needed
                [not build tested]
      sparc - simplified it using $(BITS)
      um - introduced a few new exported variables to deal with this
      xtensa - added options to CPP invocation
               [not build tested]

      [UML] fix gcc ICEs and unresolved externs · 4f81c535
      Jeff Dike 提交于
      There are various constraints on the use of unit-at-a-time:
       - i386 uses no-unit-at-a-time for pre-4.0 (not 4.3)
       - x86_64 uses unit-at-a-time always
      
      Uli reported a crash on x86_64 with gcc 4.1.2 with unit-at-a-time,
      resulting in commit c0a18111
      
      Ingo reported a gcc internal error with gcc 4.3 with no-unit-at-a-timem,
      resulting in 22eecde2
      
      Benny Halevy is seeing extern inlines not resolved with gcc 4.3 with
      no-unit-at-a-time
      
      This patch reintroduces unit-at-a-time for gcc >= 4.0, bringing back the
      possibility of Uli's crash.  If that happens, we'll debug it.
      
      I started seeing both the internal compiler errors and unresolved
      inlines on Fedora 9.  This patch fixes both problems, without so far
      reintroducing the crash reported by Uli.

      uml: runtime host VMSPLIT detection · 536788fe
      Jeff Dike 提交于
      Calculate TASK_SIZE at run-time by figuring out the host's VMSPLIT - this is
      needed on i386 if UML is to run on hosts with varying VMSPLITs without
      recompilation.
      
      TASK_SIZE is now defined in terms of a variable, task_size.  This gets rid of
      an include of pgtable.h from processor.h, which can cause include loops.
      
      On i386, task_size is calculated early in boot by probing the address space in
      a binary search to figure out where the boundary between usable and non-usable
      memory is.  This tries to make sure that a page that is considered to be in
      userspace is, or can be made, read-write.  I'm concerned about a system-global
      VDSO page in kernel memory being hit and considered to be a userspace page.
      
      On x86_64, task_size is just the old value of CONFIG_TOP_ADDR.
      
      A bunch of config variable are gone now.  CONFIG_TOP_ADDR is directly replaced
      by TASK_SIZE.  NEST_LEVEL is gone since the relocation of the stubs makes it
      irrelevant.  All the HOST_VMSPLIT stuff is gone.  All references to these in
      arch/um/Makefile are also gone.
      
      I noticed and fixed a missing extern in os.h when adding os_get_task_size.
      
      Note: This has been revised to fix the 32-bit UML on 64-bit host bug that
      Miklos ran into.

      uml: throw out CONFIG_MODE_TT · 42fda663
      Jeff Dike 提交于
      This patchset throws out tt mode, which has been non-functional for a while.
      
      This is done in phases, interspersed with code cleanups on the affected files.
      
      The removal is done as follows:
      	remove all code, config options, and files which depend on
      CONFIG_MODE_TT
      	get rid of the CHOOSE_MODE macro, which decided whether to
      call tt-mode or skas-mode code, and replace invocations with their
      skas portions
      	replace all now-trivial procedures with their skas equivalents
      
      There are now a bunch of now-redundant pieces of data structures, including
      mode-specific pieces of the thread structure, pt_regs, and mm_context.  These
      are all replaced with their skas-specific contents.
      
      As part of the ongoing style compliance project, I made a style pass over all
      files that were changed.  There are three such patches, one for each phase,
      covering the files affected by that phase but no later ones.
      
      I noticed that we weren't freeing the LDT state associated with a process when
      it exited, so that's fixed in one of the later patches.
      
      The last patch is a tidying patch which I've had for a while, but which caused
      inexplicable crashes under tt mode.  Since that is no longer a problem, this
      can now go in.
      
      This patch:
      
      Start getting rid of tt mode support.
      
      This patch throws out CONFIG_MODE_TT and all config options, code, and files
      which depend on it.
      
      CONFIG_MODE_SKAS is gone and everything that depends on it is included
      unconditionally.
      
      The few changed lines are in re-written Kconfig help, lines which needed
      something skas-related removed from them, and a few more which weren't
      strictly deletions.

      uml: fix an IPV6 libc vs kernel symbol clash · 818f6ef4
      Jeff Dike 提交于
      On some systems, with IPV6 configured, there is a clash between the kernel's
      in6addr_any and the one in libc.
      
      This is handled in the usual (gross) way of defining the kernel symbol out of
      the way on the gcc command line.

      One usecase is when trying to find gcc bugs but other
      use cases has been requested too.

      alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k
      
      Test was simple to do a defconfig build, apply the patch and check

      minimal build fixes for uml (fallout from x86 merge) · 2b8232ce
      Al Viro 提交于
       a) include/asm-um/arch can't just point to include/asm-$(SUBARCH) now
       b) arch/{i386,x86_64}/crypto are merged now
       c) subarch-obj needed changes
       d) cpufeature_64.h should pull "cpufeature_32.h", not <asm/cpufeature_32.h>
          since it can be included from asm-um/cpufeature.h
       e) in case of uml-i386 we need CONFIG_X86_32 for make and gcc, but not
          for Kconfig
       f) sysctl.c shouldn't do vdso_enabled for uml-i386 (actually, that one
          should be registered from corresponding arch/*/kernel/*, with ifdef
          going away; that's a separate patch, though).
      
      With that and with Stephen's patch ("[PATCH net-2.6] uml: hard_header fix")
      we have uml allmodconfig building both on i386 and amd64.
