      m68k: Disable Amiga serial console support if modular · d1a35e4d
      Geert Uytterhoeven authored 
      If CONFIG_AMIGA_BUILTIN_SERIAL=m, I get the following warnings:

| drivers/char/amiserial.c: At top level:
| drivers/char/amiserial.c:2138: warning: data definition has no type or storage class
| drivers/char/amiserial.c:2138: warning: type defaults to 'int' in declaration of 'console_initcall'
| drivers/char/amiserial.c:2138: warning: parameter names (without types) in function declaration
| drivers/char/amiserial.c:2134: warning: 'amiserial_console_init' defined but not used

because console_initcall() is not defined (nor really sensible) in the
modular case.

So disable serial console support if the driver is modular.

      epoll: avoid double-inserts in case of EFAULT · 9ce209d6
      Davide Libenzi authored 
      In commit f337b9c5 ("epoll: drop
unnecessary test") Thomas found that there is an unnecessary (always
true) test in ep_send_events().  The callback never inserts into
->rdllink while the send loop is performed, and also does the
~EP_PRIVATE_BITS test.  Given we're holding the mutex during this time,
the conditions tested inside the loop are always true.

HOWEVER.

The test "!ep_is_linked(&epi->rdllink)" wasn't there because we insert
into ->rdllink, but because the send-events loop might terminate before
the whole list is scanned (-EFAULT).

In such cases, when the loop terminates early, and when a (leftover)
file received an event while we're performing the lockless loop, we need
such test to avoid to double insert the epoll items.  The list_splice()
done a few steps below, will correctly re-insert the ones that were left
on "txlist".

This should fix the kenrel.org bugzilla entry 11831.

      select: deal with math overflow from borderline valid userland data · 4d36a9e6
      Arjan van de Ven authored 
      Some userland apps seem to pass in a "0" for the seconds, and several
seconds worth of usecs to select().  The old kernels accepted this just
fine, so the new kernels must too.

However, due to the upscaling of the microseconds to nanoseconds we had
some cases where we got math overflow, and depending on the GCC version
(due to inlining decisions) that actually resulted in an -EINVAL return.

This patch fixes this by adding the excess microseconds to the seconds
field.

Also with thanks to Marcin Slusarz for spotting some implementation bugs
in the diagnostics patches.

      wireless: fix regression caused by regulatory config option · 44a504c4
      Arjan van de Ven authored 
      The default for the regulatory compatibility option is wrong;
if you picked the default you ended up with a non-functional wifi
system (at least I did on Fedora 9 with iwl4965).
I don't think even the October 2008 releases of the various distros
has the new userland so clearly the default is wrong, and also
we can't just go about deleting this in 2.6.29...

Change the default to "y" and also adjust the config text a little to
reflect this.

This patch fixes regression #11859

With thanks to Johannes Berg for the diagnostics

      r8169: revert "read MAC address from EEPROM on init" · e383d564
      Francois Romieu authored 
      This reverts commit 7bf6bf48.

The code has both a short existence and an increasing track of failures
despite some work to amend it for -rc1.  It is not just a matter of
reading the eeprom: sometimes the eeprom is read correctly, then the mac
address is not written correctly back into the mac registers.

Some chipsets seem to work reliably but it is not clear at this point if
the code can simply be made to work on a per-chipset basis and post -rc1
is not the place where I want to experiment these things.

      a) semicolon before the function body is a bad idea
b) it's const struct foo, not struct const foo
c) incidentally, it's ecard_remove_driver(), not ecard_unregister_driver()
d) compiling is occasionally useful.

      fix allmodconfig breakage · ce97e13e
      Al Viro authored 
      If you use KCONFIG_ALLCONFIG (even with empty file) you get broken
allmodconfig/allyesconfig; CONFIG_MODULES gets turned off, with obvious
massive fallout.

Breakage had been introduced when conf_set_all_new_symbols() got used
for allmodconfig et.al.

What happens is that sym_calc_value(modules_sym) done in
conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES.
When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER]
on everything, but it has no effect on sym->curr for the symbols that
already have SYMBOL_VALID - these are stuck.

Solution: use sym_clear_all_valid() in there.  Note that it makes
reevaluation of modules_sym redundant - sym_clear_all_valid() will do
that itself.

[ Fixes http://bugzilla.kernel.org/show_bug.cgi?id=11512, says Alexey ]
