The first 4k region of CCSR space is well defined for local access
windows, CCSRBAR, etc.  The second 4k region is well defined as
register for configuring and getting errors for the ECM coherency

Linus Torvalds [Sat, 16 May 2009 20:41:28 +0000]
Fix caller information for warn_slowpath_null

Ian Campbell noticed that since "Eliminate thousands of warnings with
gcc 3.2 build" (commit 57adc4d2dbf968fdbe516359688094eef4d46581) all
WARN_ON()'s currently appear to come from warn_slowpath_null(), eg:

  WARNING: at kernel/softirq.c:143 warn_slowpath_null+0x1c/0x20()

because now that warn_slowpath_null() is in the call path, the
__builtin_return_address(0) returns that, rather than the place that
caused the warning.

Fix this by splitting up the warn_slowpath_null/fmt cases differently,
using a common helper function, and getting the return address in the
right place.  This also happens to avoid the unnecessary stack usage for
the non-stdargs case, and just generally cleans things up.

Make the function name printout use %pS while at it.

Processor idle power states C2 and C3 stop the TSC on many machines.
Linux recognizes this situation and marks the TSC as unstable:

Marking TSC unstable due to TSC halts in idle

when filling out the READ CAPACITY(16) response.

This patch is based upon code from Matthew Wilcox' 4KB ATA tree.  I
fixed the bug I reported a while back caused by ATA and SCSI using
different approaches to describing the alignment.

devpts: correctly set default options

devpts_get_sb() calls memset(0) to clear mount options and calls
parse_mount_options() if user specified any mount options.

The memset(0) is bogus since the 'mode' and 'ptmxmode' options are
non-zero by default.  parse_mount_options() restores options to default
anyway and can properly deal with NULL mount options.

So in devpts_get_sb() remove memset(0) and call parse_mount_options() even
for NULL mount options.

ext4: Fix race in ext4_inode_info.i_cached_extent

If two CPU's simultaneously call ext4_ext_get_blocks() at the same
time, there is nothing protecting the i_cached_extent structure from
being used and updated at the same time.  This could potentially cause
the wrong location on disk to be read or written to, including
potentially causing the corruption of the block group descriptors
and/or inode table.

This bug has been in the ext4 code since almost the very beginning of
ext4's development.  Fortunately once the data is stored in the page
cache cache, ext4_get_blocks() doesn't need to be called, so trying to
replicate this problem to the point where we could identify its root
cause was *extremely* difficult.  Many thanks to Kevin Shanahan for
working over several months to be able to reproduce this easily so we
could finally nail down the cause of the corruption.

10 years agopowerpc: Fix PCI ROM access
Benjamin Herrenschmidt [Thu, 14 May 2009 20:16:47 +0000]
powerpc: Fix PCI ROM access

A couple of issues crept in since about 2.6.27 related to accessing PCI
device ROMs on various powerpc machines.

First, historically, we don't allocate the ROM resource in the resource
tree. I'm not entirely certain of why, I susepct they often contained
garbage on x86 but it's hard to tell. This causes the current generic
code to always call pci_assign_resource() when trying to access the said
ROM from sysfs, which will try to re-assign some new address regardless
of what the ROM BAR was already set to at boot time. This can be a
problem on hypervisor platforms like pSeries where we aren't supposed
to move PCI devices around (and in fact probably can't).

Second, our code that generates the PCI tree from the OF device-tree
(instead of doing config space probing) which we mostly use on pseries
at the moment, didn't set the (new) flag IORESOURCE_SIZEALIGN on any
resource. That means that any attempt at re-assigning such a resource
with pci_assign_resource() would fail due to resource_alignment()
returning 0.

This fixes this by doing these two things:

 - The code that calculates resource flags based on the OF device-node
is improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at
it also set IORESOURCE_READONLY for ROMs since we were lacking that too

 - We now allocate ROM resources as part of the resource tree. However
to limit the chances of nasty conflicts due to busted firmwares, we
only do it on the second pass of our two-passes allocation scheme,
so that all valid and enabled BARs get precedence.

This brings pSeries back the ability to access PCI ROMs via sysfs (and
thus initialize various video cards from X etc...).

powerpc/cell: Make ptcal more reliable

There have been a series of checkstops on QS21 related to
ptcal being set up incorrectly. On systems that only
have memory on a single node, ptcal fails when it gets
a pointer to memory on the remote node.

Moreover, agressive prefetching in memcpy and other
functions may accidentally touch the first cache line
of the page that we reserve for ptcal, which causes
an ECC checkstop.

We now allocate pages only from the specified node, moves the
ptcal area into the middle of the allocated page to avoid
potential prefetch problems and prints the address of the

powerpc/mpic: Fix incorrect allocation of interrupt rev-map

Before when we were setting up the irq host map for mpic we passed in
just isu_size for the size of the linear map.  However, for a number of
mpic implementations we have no isu (thus pass in 0) and will end up
with a no linear map (size = 0).  This causes us to always call
irq_find_mapping() from mpic_get_irq().

By moving the allocation of the host map to after we've determined the
number of sources we can actually benefit from having a linear map for
the non-isu users that covers all the interrupt sources.

events (i.e., "PM_MRK_<event-name>").  In processors prior to POWER6, the MMCRA
register contained "slot information" that the oprofile kernel driver used to
adjust the value latched in the SIAR at the time of a PMU interrupt.  But as of
POWER6, these slot bits in MMCRA are no longer necessary for oprofile to use,
since the SIAR itself holds the accurate sampled instruction address.  With
POWER6, these MMCRA slot bits were zero'ed out by hardware so oprofile's use of
these slot bits was, in effect, a NOP.  But with POWER7, these bits are no
longer zero'ed out; however, they serve some other purpose rather than slot
information.  Thus, using these bits on POWER7 to adjust the SIAR value results
in samples being attributed to the wrong instructions.  The attached patch
changes the oprofile kernel driver to ignore these slot bits on all newer
processors starting with POWER6.

powerpc/iseries: Fix pci breakage due to bad dma_data initialization

Commit 4fc665b88a79a45bae8bbf3a05563c27c7337c3d "powerpc: Merge 32 and
64-bit dma code" made changes to the PCI initialisation code that added
an assignment to archdata.dma_data but only for 32 bit code.  Commit
7eef440a545c7f812ed10b49d4a10a351df9cad6 "powerpc/pci: Cosmetic cleanups
of pci-common.c" removed the conditional compilation.  Unfortunately,
the iSeries code setup the archdata.dma_data before that assignment was
done - effectively overwriting the dma_data with NULL.

Fix this up by moving the iSeries setup of dma_data into a
pci_dma_dev_setup callback.

drm/i915: ignore LVDS on intel graphics systems that lie about having it

There are a number of small form factor desktop systems with Intel mobile
graphics chips that lie and say they have an LVDS. With kernel mode-setting,
this becomes a problem, and makes native resolution boot go haywire -- for
example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to
have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080
display uses only the top left 1024x768, and auto-configured X will end
up only 1024x768 as well. With this change, graphical boot and X
both do 1920x1080 as expected.

Note that we're simply embracing and extending the early bail-out code
in place for the Mac Mini here. The xorg intel driver uses pci subsystem
device and vendor id for matching, while we're using dmi lookups here.

drm/i915: sanity check IER at wait_request time

We might sleep here anyway so I hope an extra uncached read is ok to
add.

In #20896 we found that vbetool clobbers the IER.  In KMS mode this is
particularly bad since we don't set the interrupt regs late (in
EnterVT), so we'd fail to get *any* interrupts at all after X started
(since some distros have scripts that call vbetool at X startup
apparently).

So this patch checks IER at wait_request time, and re-enables
interrupts if it's been clobbered.  In a proper config this check
should never be triggered.

This is really a distro issue, but having a sanity check is nice, as
long as it doesn't have a real performance hit.

ext4: Clear the unwritten buffer_head flag after the extent is initialized

The BH_Unwritten flag indicates that the buffer is allocated on disk
but has not been written; that is, the disk was part of a persistent
preallocation area.  That flag should only be set when a get_blocks()
function is looking up a inode's logical to physical block mapping.

When ext4_get_blocks_wrap() is called with create=1, the uninitialized
extent is converted into an initialized one, so the BH_Unwritten flag
is no longer appropriate.  Hence, we need to make sure the
BH_Unwritten is not left set, since the combination of BH_Mapped and
BH_Unwritten is not allowed; among other things, it will result ext4's

Alan Jenkins [Mon, 27 Apr 2009 07:23:39 +0000]
eeepc-laptop: Work around rfkill firmware bug

1) Buggy firmware can change the RFKILL state by itself. This is easily
   detected.  The RFKILL API states that in such cases, we should call
   rfkill_force_state() to notify the core.

   I have reported the bug to Asus. I believe this is the right thing
   to do for robustness, even if this particular firmware bug is fixed.

2) The same bug causes the wireless toggle key to be reported as 0x11
   instead of 0x10.  0x11 is otherwise unused, so it should be safe to
   add this as a new keycode.

The bug is triggered by removing the laptop battery while hibernated.

On resume, the wireless toggle key causes the firmware to toggle the
wireless state itself.  (Also, the key is reported as 0x11 when the
current wireless state is OFF).

This is very poor behaviour because the OS can't predict whether the
firmware is controlling the RFKILL state.

Without this workaround, the bug means users have to press the wireless
toggle key twice to enable, due to the OS/firmware conflict.  (Assuming
rfkill-input or equivalent is being used).  The workaround avoids this.

I believe that acpid scripts which toggle the value of the sysfs state file
when the toggle key is pressed will be rendered ineffective by the bug,
regardless of this workaround.  If they simply toggle the state, when the
firmware has already toggled it, then you will never see a state change.

Tested on "EEEPC 4G" only.

eeepc-laptop: report brightness control events via the input layer

This maps the brightness control events to one of two keys, either
KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP, as needed.

Some mapping has to be done due to the fact that the BIOS reports them as
<base value> + <current brightness index>; the selection is done according to
the sign of the change in brightness (if this is 0, no keypress is reported).

10 years agoeeepc-laptop: fix wlan rfkill state change during init
Alan Jenkins [Mon, 27 Apr 2009 07:23:37 +0000]
eeepc-laptop: fix wlan rfkill state change during init

When an rfkill device is registered, the rfkill core will change its
state to the system default. So we need to prepare for state changes
*before* we register it. That means installing the eeepc-specific ACPI
callback which handles the hotplug of the wireless network adaptor.

This problem doesn't occur during normal operation.  You have to

1) Boot with wireless enabled. eeepc-laptop should load automatically.
2) modprobe -r eeepc-laptop
3) modprobe eeepc-laptop

On boot, the default rfkill state will be set to enabled.
With the current core code, step 2) will disable the wireless.
Therefore in step 3), the wireless will change state during registration,
from disabled to enabled.  But without this fix, the PCI device for the
wireless adaptor will not appear.

MIPS: Use force_sig when handling address errors.

When init is started it is SIGNAL_UNKILLABLE.  If it were to get an
address error, we would try to send it SIGBUS, but it would be ignored
and the faulting instruction restarted.  This results in an endless
loop.

We need to use force_sig() instead so it will actually die and give us
some useful information.
