2012-06-20T21:39:35+00:00

Cleanups:
  - Include ,

xtensa: use "test -e" instead of bashism "test -a"

2012-06-20T21:39:35+00:00

On Ubuntu, /bin/sh is a symlink to dash, which does not support "test -a".
This causes messages like

    test: 1: -a: unexpected operator
    test: 1: -a: unexpected operator

and link failures like

    (.init.text+0x132): undefined reference to `platform_init'

due to the appropriate platform code not being compiled.

xtensa: replace xtensa-specific _f{data,text} by _s{data,text}

2012-06-20T21:39:35+00:00

commit a2d063ac216c161 ("extable, core_kernel_data(): Make sure all archs
define _sdata") missed xtensa.  Xtensa does have a start of data marker,
but calls it _fdata, causing

    kernel/built-in.o:(.text+0x964): undefined reference to `_sdata'

_stext was already defined, but it was duplicated by _fdata.

fixups for signal breakage

new helper: signal_delivered()

2012-06-01T16:58:52+00:00

Does block_sigmask() + tracehook_signal_handler();  called when
sigframe has been successfully built.  All architectures converted
to it; block_sigmask() itself is gone now (merged into this one).

I'm still not too happy with the signature, but that's a separate
story (IMO we need a structure that would contain signal number +
siginfo + k_sigaction, so that get_signal_to_deliver() would fill one,
signal_delivered(), handle_signal() and probably setup...frame() -
take one).

most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from set

2012-06-01T16:58:51+00:00

Only 3 out of 63 do not.  Renamed the current variant to __set_current_blocked(),
added set_current_blocked() that will exclude unblockable signals, switched
open-coded instances to it.

don't call try_to_freeze() from do_signal()

get_signal_to_deliver() will handle it itself

new helper: sigmask_to_save()

2012-06-01T16:58:48+00:00

replace boilerplate "should we use ->saved_sigmask or ->blocked?"
with calls of obvious inlined helper...
