      rename thread_info to stack · f7e4217b
      由 Roman Zippel 提交于 
      This finally renames the thread_info field in task structure to stack, so that
the assumptions about this field are gone and archs have more freedom about
placing the thread_info structure.

Nonbroken archs which have a proper thread pointer can do the access to both
current thread and task structure via a single pointer.

It'll allow for a few more cleanups of the fork code, from which e.g.  ia64
could benefit.

      [PATCH] x86: PARAVIRT: add hooks to intercept mm creation and destruction · d6dd61c8
      由 Jeremy Fitzhardinge 提交于 
      Add hooks to allow a paravirt implementation to track the lifetime of
an mm.  Paravirtualization requires three hooks, but only two are
needed in common code.  They are:

arch_dup_mmap, which is called when a new mmap is created at fork

arch_exit_mmap, which is called when the last process reference to an
  mm is dropped, which typically happens on exit and exec.

The third hook is activate_mm, which is called from the arch-specific
activate_mm() macro/function, and so doesn't need stub versions for
other architectures.  It's called when an mm is first used.

      [PATCH] consolidate line discipline number definitions · 4564f9e5
      由 Tilman Schmidt 提交于 
      The line discipline numbers N_* are currently defined for each architecture
individually, but (except for a seeming mistake) identically, in
asm/termios.h.  There is no obvious reason why these numbers should be
architecture specific, nor any apparent relationship with the termios
structure.  The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway.  So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.

Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.

      [PATCH] m68k: work around binutils tokenizer change · 38135614
      由 Al Viro 提交于 
      Recent as(1) doesn't think that .  terminates a macro name, so getuser.l is
_not_ treated as invoking getuser with .l as the first argument.
arch/m68k/math-emu relies on old behaviour, so it gets a lot of undefined
macros with more or less current binutils.

Note that this behaviour remains in all recent versions and is unrelated to
another binutils problems we used to have for a while (having (%a0)+ parsed
as two arguments).  This one is there to stay; it's an intentional and
documented change.

.irp <identifier> <words>
[text]
.endr
expands to a copy of text per each word, with \<identifier> replaced with
corresponding word.  Again, what happens depends on whether gas_ident.x
is treated as one or as two tokens; in the former case we'll get old_gas
incremented once, in the latter - twice.  The rest is obvious.

Unlike .macro argument list _anything_ is explicitly allowed after
.irp <identifier>; here we are on very safe ground.  And yes, it does
work with all gas variants I've got here (including vanilla 2.15, 2.16,
2.16.1 and 2.17, plus debian and FC binutils).

      [PATCH] tty: preparatory structures for termios revamp · be90038a
      由 Alan Cox 提交于 
      In order to sort out our struct termios and add proper speed control we need
to separate the kernel and user termios structures.  Glibc is fine but the
other libraries rely on the kernel exported struct termios and we need to
extend this without breaking the ABI/API

To do so we add a struct ktermios which is the kernel view of a termios
structure and overlaps the struct termios with extra fields on the end for
now.  (That limitation will go away in later patches).  Some platforms (eg
alpha) planned ahead and thus use the same struct for both, others did not.

This just adds the structures but does not use them, it seems a sensible
splitting point for bisect if there are compile failures (not that I expect
them)

      [PATCH] m68k pt_regs fixes · 2850bc27
      由 Al Viro 提交于 
      m68k_handle_int() split in two functions: __m68k_handle_int() takes
pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs
*.

Places where we used to call m68k_handle_int() recursively with the same
pt_regs have simply lost the second argument, the rest is switched to
__m68k_handle_int().

The rest of patch is just dropping pt_regs * where needed.
