the separate .o for libc_pic.a. This prevents rtld from making the

baf28b69f4 - According to specification, SI_USER code should only be generated by
standard kill(). On other systems, SI_LWP is generated by lwp_kill().
  This will allow conforming applications to differentiate between
  signals generated by standard events and those generated by other
  implementation events in a manner compatible with existing practice.

b57429d082 Create a checklist and call one of the *printw() functions from the
selected() callback. When the dialog first appears, you will not see
the printed statement on the dialog, if you move down one, you will,
move up again and it now appears. I am assuming that you call a
*printw() function on a line in the dialog box of course.

The fix, from the pr:
	This is a hack at best, I looked at the redraw code in
	dialog_checklist() and took the minimal amount of it out to do
	a simple "refresh" right after the items are drawn. This
	doesn't hurt anything and makes the library work like it
	should. There is probably a better way however =).

0c898ccd30 Mark the following static variables as __used__ instead of __unused__:
o force_to_data
o __CTOR_LIST__
o __do_global_dtors_aux_fini_array_entry
o __frame_dummy_init_array_entry

This is necessary because Clang is smart enough to optimize out these
variables was they were marked as __unused__ (and they are also static).
The end result was programs segfaulting because these symbols weren't
present.

This follows the upstream revision 159228 and the author of that
revision (Jan Hubicka <jh at suse.de>) allowed us to backport this to our
GPLv2 GCC.

9ae11bbaa6 Implement basic WOL support. Note, not all xl(4) controllers

ac68109179 Move xl_reset() to xl_init_locked(). This will make driver
initialize controller from a known good state. Previously driver
used to issue controller reset while TX/RX DMA are in progress.
I guess resetting controller in active TX/RX DMA cycle is to ensure
stopping I/Os in xl_shutdown(). I remember some buggy controllers
didn't respond with stop command if controller is under high
network load at the time of shutdown so resetting controller was
the only safe way to stop the I/Os. However, from my experiments,
controller always responded with stop command under high network
load so I think it's okay to remove the xl_reset() in
device_shutdown handler.
Resetting controller also will clear configured RX filter which
in turn will make WOL support hard because driver have to reprogram
RX filter in WOL handler as well as setting station address.

ea246b6369 On shared object unload, in __cxa_finalize, call and clear all installed
atexit and __cxa_atexit handlers that are either installed by unloaded
dso, or points to the functions provided by the dso.

Use _rtld_addr_phdr to locate segment information from the address of
private variable belonging to the dso, supplied by crtstuff.c. Provide
utility function __elf_phdr_match_addr to do the match of address against
dso executable segment.

Call back into libthr from __cxa_finalize using weak
__pthread_cxa_finalize symbol to remove any atfork handler which
function points into unloaded object.

The rtld needs private __pthread_cxa_finalize symbol to not require
resolution of the weak undefined symbol at initialization time. This
cannot work, since rtld is relocated before sym_zero is set up.

c09808d0d6 MFtbemd:
Use MACHINE_CPUARCH in preference to MACHINE_ARCH.  The former is the

we're tesitng for a specific target.  The isn't even moot for

b817ddc741 Document tunable dev.rl.%unit.prefer_iomap 2010-08-22 21:32:48 +00:00
Pyun YongHyeon
c6a3d2bb77 It seems some newer RTL8139 controllers provides only memory space
register mapping. I'm not sure whether it comes from the fact that
controllers live behind certain PCI brdge(PLX PCI 6152 33BC) and
the bridge has some issues in handling I/O space register mapping.
Unfortunately it's not possible to narrow down to an exact
controller that shows this issue because RealTek used the same PCI
device/revision id again. In theory, it's possible to check parent
PCI bridge device and change rl(4) to use memory space register
mapping if the parent PCI bridge is PLX PCI 6152. But I didn't try
to do that and we wouldn't get much benefit with added complexity.

Blindly switching to use memory space register mapping for rl(4)
may make most old controllers not to work. At least, I don't want
to take potential risk from such change. So use I/O space register
mapping by default but give users chance to override it via a
tunable. The tunable to use memory space register mapping would be
given by adding the following line to /boot/loader.conf file.

dev.rl.%d.prefer_iomap="0"

This change makes P811B quad-port work with this tunable.
