powerpc: Rewrite sysfs processor cache info code

The current code for providing processor cache information in sysfs
has the following deficiencies:
- several complex functions that are hard to understand
- implicit recursion (cache_desc_release -> kobject_put -> cache_desc_release)
- explicit recursion (create_cache_index_info)
- use of two per-cpu arrays when one would suffice
- duplication of work on systems where CPUs share cache

Also, when I looked at implementing support for a shared_cpu_map
attribute, it was pretty much impossible to handle hotplug without
checking every single online CPU's cache_desc list and fixing things
up... not that this is a hot path, but it would have introduced
O(n^2)-ish behavior during boot.  Addressing this involved rethinking
the core data structures used, which didn't lend itself to an
incremental approach.

This implementation maintains a "forest" (potentially more than one
tree) of cache objects which reflects the system's cache topology.
Cache objects are instantiated as needed as CPUs come online.  A
per-cpu array is used mainly for sysfs-related bookkeeping; the
objects in the array just point to the appropriate points in the
forest.

This maintains compatibility with the existing code and includes some
enhancements:
- Implement the shared_cpu_map attribute, which is essential for
  enabling userspace to discover the system's overall cache topology.
- Use cache-block-size properties if cache-line-size is not available.

I chose to place this implementation in a new file since it would have
roughly doubled the size of sysfs.c, which is already kind of messy.

15 years agopowerpc/pci: Reserve legacy regions on PCI
Benjamin Herrenschmidt [Tue, 11 Nov 2008 17:45:52 +0000 (17:45 +0000)]
powerpc/pci: Reserve legacy regions on PCI

There's a problem on some embedded platforms when we re-assign
everything on PCI, such as 44x. The generic code tries to avoid
assigning devices to addresses overlapping the low legacy
addresses such as VGA hard decoded areas using constants that
are unfortunately no good for us, as they don't take into account
the address translation we do to access PCI busses.

Thus we end up allocating things like IO BARs to 0, which is
technically legal, but will shadow hard decoded ports for use
by things like VGA cards.

This works around it by attempting to reserve legacy regions
before we try to assign addresses.

NOTE: This may have nasty side effects in cases I haven't tested
yet:

 - We try to use FW mappings (ie. powermac) and the FW has allocated
a conflicting address over those legacy regions. This will typically
happen. I would expect the new code to just fail with an informative
message without harm but I haven't had a chance to test that scenario
yet.

 - A device with fixed BARs overlapping those legacy addresses such
as an IDE controller in legacy mode is in the system. I don't know
for sure yet what will happen there, I have to test :-)

Ideally, we should change PCIBIOS_MIN_IO/MIN_MEM accross the board
to take a bus pointer so they can provide appropriate per-bus translated
values to the generic code but that's a more invasive patch. I will
do that in the future, but in the meantime, this fixes the problem
locally

V4L/DVB (10191a): Update MAINTAINERS entries on media drivers

This patch updates the MAINTAINERS entries for the media drivers.

We are doing a few changes during 2009 to improve patch handling for
drivers/media stuff.

Currently, v4l-dvb-maintainer list at linuxtv.org were used to to be v4l/dvb
driver maintainers ML, in order to keep track of patch merge requests and to
receive bug fixes. This list allows posting for everybody, but, in order to
avoid spam, the user subscribe/unsubscribe at the ML is moderated. Other
development discussions and end-user forums happened on two separated ML (one
for V4L and another for DVB).

At the beginning of 2009, we've created linux-media@vger.kernel.org, meaning to
be the main upstream development mailing list for drivers/media, including V4L
and DVB core and drivers.

The choice for vger.kernel.org were due to the fact that most of upstream lists
are there. Also, its anti-spam filtering rules are better than what we
currently have at linuxtv.org.

For now, both video4linux-list and linux-dvb ML will remain active, but more
focused on end users. It is expected that those lists will gradually be
replaced also by linux-media@vger.kernel.org.

This patch reflect those changes at linux MAINTAINERS file.

Since the development and bug fix discussions will now happen at
linux-media@vger.kernel.org, this patch does the following changes

- replaces v4l-dvb-maintainer ML for the new
  linux-media@vger.kernel.org;

- replaces video4linux ML for the new linux-media@vger.kernel.org;

While here, it also:

- Fixes the existing -git tree entries for drivers/media (since the
          repository name changed);

- Adds the missing drivers/media -git tree entry on a few maintainers
          entries that don't point to a tree.

V4L/DVB (10190): cx88: Fix some Kbuild troubles

As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues:

drivers/built-in.o: In function `cx88_call_i2c_clients':
(.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend'
drivers/built-in.o: In function `cx8802_probe':
cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend'
cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends'

With those configs:

CONFIG_VIDEO_CX88=y
CONFIG_VIDEO_CX88_BLACKBIRD=y
CONFIG_VIDEO_CX88_DVB=m
CONFIG_DVB_CORE=m

After carefully examining the code, with the current code, several cx88 drivers
(cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module,
if one of them is marked as such. Just fixing Kconfig could create a very complex
set of rules. Also, this hides a problem with the current approach where the dvb
functionality weren't confined inside dvb module.

What happens is that:
- cx88-i2c (part of cx8800) has some special rules if DVB;
- cx88-mpeg (cx8802 module) has also part of DVB init code;
- cx88-dvb has the rest of the dvb code;
- cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not.

So, instead of doing some tricks at Kconfig and wait for a next breakage,
this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb.

Another problem is that cx8802 were being compiled, even without cx88-dvb
and cx88-blackbird modules.

While on this code, let's fix also a reported problem:
http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html

A solution for the issue were proposed here:

and solve the issues.

that text format. This is always done at make time anyways.

And this triggers the Makefile rules to update ihex2fw.

There were two solutions for this issue:
1) Move the list of firmware blobs to a separate file
2) Avoid ihex2fw rebuild by moving it to scripts

svc: Move kfree of deferral record to common code

The rqstp structure has a pointer to a svc_deferred_req record
that is allocated when requests are deferred. This record is common
to all transports and can be freed in common code.

Move the kfree of the rq_deferred to the common svc_xprt_release
function.

This also fixes a memory leak in the RDMA transport which does not
kfree the dr structure in it's version of the xpo_release_rqst callback.

CRED: Fix NFSD regression

Fix a regression in NFSD's permission checking introduced by the credentials
patches.  There are two parts to the problem, both in nfsd_setuser():

 (1) The return value of set_groups() is -ve if in error, not 0, and should be
     checked appropriately.  0 indicates success.

 (2) The UID to use for fs accesses is in new->fsuid, not new->uid (which is
     0).  This causes CAP_DAC_OVERRIDE to always be set, rather than being
     cleared if the UID is anything other than 0 after squashing.

nfsd: Ensure nfsv4 calls the underlying filesystem on LOCKT

Since nfsv4 allows LOCKT without an open, but the ->lock() method is a
file method, we fake up a struct file in the nfsv4 code with just the
fields we need initialized.  But we forgot to initialize the file
operations, with the result that LOCKT never results in a call to the
filesystem's ->lock() method (if it exists).

We could just add that one more initialization.  But this hack of faking
up a struct file with only some fields initialized seems the kind of
thing that might cause more problems in the future.  We should either do
an open and get a real struct file, or make lock-testing an inode (not a
file) method.

This patch does the former.

stop_machine/cpu hotplug: fix disable_nonboot_cpus

disable_nonboot_cpus calls _cpu_down. But _cpu_down requires that the
caller already created the stop_machine workqueue (like cpu_down does).
Otherwise a call to stop_machine will lead to accesses to random memory
regions.

When introducing this new interface (9ea09af3bd3090e8349ca2899ca2011bd94cda85

call site of _cpu_down.
So add the missing stop_machine_create/destroy calls to disable_nonboot_cpus
as well.

Still, we can make the default PM callbacks run for devices with
drivers using the new framework (ie. implement the pm object), since
there are no such drivers at the moment.

This also simplifies the code and makes it smaller.

PCI PM: Register power state of devices during initialization

Use the observation that the power state of a PCI device can be
loaded into its pci_dev structure as soon as pci_pm_init() is run for
it and make that happen.

PCI PM: Call pci_fixup_device from legacy routines

The size of drivers/pci/pci-driver.c can be reduced quite a bit
if pci_fixup_device() is called from the legacy PM callbacks, so make
it happen.

No functional changes should result from this.
