b0d98dc504 sh: Support PCI IO access of SH7780 base boards.
The IO access of PCI is not supported in R7780RP and the MS7780SE
board now. The support of the IO access mode of e100 and a lot of IDE
chips becomes possible by fixing the code.

d0a6895751 libertas: Don't set NETIF_F_IPV6_CSUM in dev->features
I'm not sure why it was doing this, and I'm not sure I _want_ to know
why. But calling it NETIF_F_DYNALLOC doesn't change the fact that the
kernel believes it to be NETIF_F_IPV6_CSUM, and that IPv6 communication
is hence buggered.

a10605e599 mac80211: free ifsta->extra_ie and clear IEEE80211_STA_PRIVACY_INVOKED
I'm not sure if this is best choice, someone might have better
solutions. But this patch fixed the connection problem when switching
from a WPA enabled AP (using wpa_supplicant) to an open AP (using
iwconfig). The root cause is when we connect to a WPA enabled AP,
wpa_supplicant sets the ifsta->extra_ie thru SIOCSIWGENIE. But if we
stop wpa_supplicant and connect to an open AP with iwconfig, there is
no way to clear the extra_ie so that mac80211 keeps connecting with that.

Someone could argue wpa_supplicant should clear the extra_ie during
its shutdown. But mac80211 should also handle the unexpected shutdown
case (ie. killall -9 wpa_supplicant).

f97b895495 x86/paravirt: revert exports to restore old behaviour
Subdividing the paravirt_ops structure caused a regression in certain
non-GPL modules which try to use mmu_ops and cpu_ops.  This restores the
old behaviour, and makes it consistent with the non-CONFIG_PARAVIRT case.

Takashi Iwai <tiwai@suse.de> adds:
> I took at this problem (as I have an nvidia card on one of my
> workstations), and found out that the following suffer from
> EXPORT_SYMBOL_GPL changes:

Christoph Hellwig objects to this patch on the grounds that modules
shouldn't be using these operations anyway.  I don't think this is a
particularly good reason to reject the patch, for several reasons:

1. These operations are still available to modules when not using
   CONFIG_PARAVIRT, since they are implicitly exported as inline
   functions via the kernel headers.  Exporting the same functionality as
   GPL-only symbols just adds a gratuitious difference between
   CONFIG_PARAVIRT and non-CONFIG_PARAVIRT configurations.  If we really
   think these operations are not for module use (or non-GPL module use),
   then we should solve the problem in a general way.

2. It's a regression from previous kernels, which would work these
   modules even with CONFIG_PARAVIRT enabled.

3. The operations in question seem pretty reasonable for modules to
   use.  The control registers/MSRs can be accessed directly anyway, so there's
   no benefit in preventing modules from using standard interfaces.  And it seems
   reasonable to allow a graphics driver to create its own mappings if it wants.

Therefore, I think this patch should go in for 2.6.24.  If people
really think that these operations should not be available to modules,
then we can address that separately.

fbb43ab03c ACPI: avoid references to impossible processors.
ACPI uses NR_CPUS in various loops and in some it accesses per cpu data of
processors that are not present(!) and that will never be present.

The pointers to per cpu data are typically not initialized for processors
that are not present.  So we seem to be reading something here from offset
0 in memory.

Make ACPI use nr_cpu_ids instead. That stops at the end of the possible
processors.

Convert one loop to NR_CPUS to use the cpu_possible map instead.  That way
ranges of processor that can never be brought online are skipped during the
loop.

e6ceb32aa2 wait_task_stopped(): pass correct exit_code to wait_noreap_copyout()
In wait_task_stopped() exit_code already contains the right value for the
si_status member of siginfo, and this is simply set in the non WNOWAIT
case.

If you call waitid() with a stopped or traced process, you'll get the signal
in siginfo.si_status as expected -- however if you call waitid(WNOWAIT) at the
same time, you'll get the signal << 8 | 0x7f

Pass it unchanged to wait_noreap_copyout(); we would only need to shift it
and add 0x7f if we were returning it in the user status field and that
isn't used for any function that permits WNOWAIT.

Arrange the sections in the FRV arch so that a BRA instruction with a
16-bit displacement can always reach from the trap table to entry.S,
tlb-miss.S and break.S.

The problem otherwise is that the linker can insert sufficient code between
the slots in the trap table and the targets of the branch instructions in
those slots that the displacement field in the instruction isn't
sufficiently large.  This is because the branch targets were in the .text
section along with most of the other code in the kernel.

7c83172b98 x86_64 EFI boot support: EFI frame buffer driver
This patch adds Graphics Output Protocol support to the kernel.  UEFI2.0 spec
deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output
Protocol (GOP) is produced.  Therefore, the boot loader needs to query the
UEFI firmware with appropriate Output Protocol and pass the video information
to the kernel.  As a result of GOP protocol, an EFI framebuffer driver is
needed for displaying console messages.  The patch adds a EFI framebuffer
driver.  The EFI frame buffer driver in this patch is based on the Intel Mac
framebuffer driver.

The ELILO bootloader takes care of passing the video information as
appropriate for EFI firmware.

The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI
platform.

f78ba15705 revert "keyspan: init termios properly"
Revert 7eea436433.

Lucy said:

  This patch will work with the 19HS but WILL BREAK all other Keyspan
  adapters.  It will take me a few days to get to looking at a correct fix but
  that keyspan_send_setup(port, 1) (and the '1' is the important part) must
  happen once when the port is first opened.  The cflag can just be set to
  whatever the normal default is for your serial environment.

So revert this again pending the proper fix.

364e3a3d8a uml: fix !NO_HZ busy-loop
With NO_HZ disabled, the UML idle loop effectively becomes a busy loop, as
it will sleep for no time.

The cause was forgetting to restart the tick after waking up from sleep.
It was disabled before sleeping, and the remaining time used as the
interval to sleep.  So, the tick needs to be restarted when nanosleep
finishes.

This is done by introducing after_sleep_interval, which is empty in the
NO_HZ case, but which sets the tick starting in the !NO_HZ case.

 Kernel panic - not syncing: Attempted to kill init!

The box has no HiSax card installed.

the reason for the crash is add_timer() done on an already running
timer. This happens because for some reason CARD_INIT is called twice.

this patch works this problem around by using mod_timer() - this gets
a booting system - but it would be nice to figure out why CARD_INIT
is done twice.
