Steven Whitehouse [Fri, 6 Nov 2009 11:06:37 +0000]
GFS2: Remove dirent_first() function

This function only had one caller left, and that caller only
called it for leaf blocks, hence one branch of the "if" was
never taken. In addition the call to get_left had already
verified the metadata type, so the function can be reduced
to a single line of code in its caller.

GFS2: Improve statfs and quota usability

GFS2 now has three new mount options, statfs_quantum, quota_quantum and
statfs_percent.  statfs_quantum and quota_quantum simply allow you to
set the tunables of the same name.  Setting setting statfs_quantum to 0
will also turn on the statfs_slow tunable.  statfs_percent accepts an
integer between 0 and 100.  Numbers between 1 and 100 will cause GFS2 to
do any early sync when the local number of blocks free changes by at
least statfs_percent from the totoal number of blocks free.  Setting
statfs_percent to 0 disables this.

GFS2: Fix -o meta mounts for subsequent mounts (i.e. all but the first one)

We have a long term plan to use the "-o meta" flag to GFS2 mounts to
access the alternate root which is used to store metadata for a GFS2
filesystem. This will allow us to eventually remove support for the
gfs2meta filesystem type (which is in any case just a "front end" to
the gfs2 filesystem type with the meta/master root).

Currently the "-o meta" option is only taken into account on the
initial mount of the filesystem. Subsequent mounts of the same
filesystem (i.e. on the same device) result in basically the same
as bind mounting the root of the original mount.

This patch changes that by using what is more or less a copy
of get_sb_bdev() and extending it so that it will take into
account the alternate root in all cases. The main difference
is that we have to parse the mount options a bit earlier. We can
then use them to select the appropriate root towards the end of
the function.

In addition this also fixes a bug where it was possible (but certainly
not desirable) to set different ro/rw options for the meta root
when mounted via the gfs2meta fs compared with the original mount.

Helge Deller [Wed, 2 Dec 2009 23:29:15 +0000]
modules: don't export section names of empty sections via sysfs

On the parisc architecture we face for each and every loaded kernel module
this kernel "badness warning":
  sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text'
  Badness at fs/sysfs/dir.c:487

Reason for that is, that on parisc all kernel modules do have multiple
.text sections due to the usage of the -ffunction-sections compiler flag
which is needed to reach all jump targets on this platform.

An objdump on such a kernel module gives:
Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .note.gnu.build-id 00000024  00000000  00000000  00000034  2**2
                  CONTENTS, ALLOC, LOAD, READONLY, DATA
  1 .text         00000000  00000000  00000000  00000058  2**0

  2 .text.ac97_bus_match 0000001c  00000000  00000000  00000058  2**2

                  CONTENTS, ALLOC, LOAD, READONLY, CODE
...
Since the .text sections are empty (size of 0 bytes) and won't be
loaded by the kernel module loader anyway, I don't see a reason
why such sections need to be listed under
/sys/module/<module_name>/sections/<section_name> either.

The attached patch does solve this issue by not exporting section
names which are empty.

  [ARM] pxamci: call mmc_remove_host() before freeing resources

9 years ago[ARM] pxamci: call mmc_remove_host() before freeing resources
Daniel Mack [Tue, 1 Dec 2009 17:17:18 +0000]
[ARM] pxamci: call mmc_remove_host() before freeing resources

mmc_remove_host() will cause the mmc core to switch off the bus power by
eventually calling pxamci_set_ios(). This function uses the regulator or
the GPIO which have been freed already.

This causes the following Oops on module unload.

9 years agortc-x1205: reset clock to sane state after power failure
Johannes Weiner [Tue, 1 Dec 2009 21:17:49 +0000]
rtc-x1205: reset clock to sane state after power failure

When detecting power failure, the probe function would reset the clock
time to defined state.

However, the clock's _date_ might still be bogus and a subsequent probe
fails when sanity-checking these values.

Change the power-failure fixup code to do a full setting of rtc_time,
including a valid date.

9 years agortc-x1205: fix rtc_time to y2k register value conversion
Johannes Weiner [Tue, 1 Dec 2009 21:17:48 +0000]
rtc-x1205: fix rtc_time to y2k register value conversion

The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
tm_year is in years since 1900.

The function translating rtc_time to register values assumes tm_year to be
years since first christmas, though, and we end up storing 0 or 1 in the
CCR_Y2K register, which the hardware does not refuse to do.

A subsequent probing of the clock fails due to the invalid value range in
the register, though.

[ And if it didn't, reading the clock would yield a bogus year because
  the function translating registers to tm_year is assuming a register
  value of 19 or 20. ]

This fixes the conversion from years since 1900 in tm_year to the
corresponding CCR_Y2K value of 19 or 20.

MIPS: Loongson: Switch from flatmem to sparsemem

With flatmem hibernation for Loongson will fail, and there are also some
other problems such as broken files when using NFS or CIFS / Samba.

The config help of sparsemem says:

"This option provides some potential performance benefits, along with
decreased code complexity."

So to avoid the potential problems of FLATMEM, we disable FLATMEM directly
and use SPARSEMEM instead.

Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on:

Kernel panic - not syncing: Attempted to kill init!

The possible reason is the cache aliases problem:

Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger
then 4kb. so, If using 4kb page size, there is cache aliases problem.
To avoid this kind of problem, extra cache flushing.  The 2nd possible
solution is 16kb page size which avoids cache aliases without the need for
extra cache flushes.  So we disable 4kB pages until the aliasing issue is
solved.

David Howells [Tue, 1 Dec 2009 13:52:08 +0000]
SLOW_WORK: Fix the CONFIG_MODULES=n case

Commits 3d7a641 ("SLOW_WORK: Wait for outstanding work items belonging to a
module to clear") introduced some code to make sure that all of a module's
slow-work items were complete before that module was removed, and commit
3bde31a ("SLOW_WORK: Allow a requeueable work item to sleep till the thread is
needed") further extended that, breaking it in the process if CONFIG_MODULES=n:

CC kernel/slow-work.o
  kernel/slow-work.c: In function 'slow_work_execute':
  kernel/slow-work.c:313: error: 'slow_work_thread_processing' undeclared (first use in this function)
  kernel/slow-work.c:313: error: (Each undeclared identifier is reported only once
  kernel/slow-work.c:313: error: for each function it appears in.)

  make[1]: *** [kernel/slow-work.o] Error 1

Fix this by:

 (1) Extracting the bits of slow_work_execute() that are contingent on
     CONFIG_MODULES, and the bits that should be, into inline functions and
     placing them into the #ifdef'd section that defines the relevant variables
     and adding stubs for moduleless kernels.  This allows the removal of some
     #ifdefs.

 (2) #ifdef'ing out the contents of slow_work_wait_for_items() in moduleless
     kernels.

The four functions related to handling module unloading synchronisation (and
their associated variables) could be offloaded into a separate .c file, but
each function is only used once and three of them are tiny, so doing so would
prevent them from being inlined.

9 years agomd: revert incorrect fix for read error handling in raid1.
NeilBrown [Tue, 1 Dec 2009 06:30:59 +0000]
md: revert incorrect fix for read error handling in raid1.

commit 4706b349f was a forward port of a fix that was needed
for SLES10.  But in fact it is not needed in mainline because
the earlier commit dd00a99e7a fixes the same problem in a
better way.
Further, this commit introduces a bug in the way it interacts with
the automatic read-error-correction.  If, after a read error is
successfully corrected, the same disk is chosen to re-read - the
re-read won't be attempted but an error will be returned instead.

After reverting that commit, there is the possibility that a
read error on a read-only array (where read errors cannot
be corrected as that requires a write) will repeatedly read the same
device and continue to get an error.
So in the "Array is readonly" case, fail the drive immediately on
a read error.

The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b54249b
"remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect

"KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]"

USB: musb: Fix CPPI IRQs not being signaled

On tx channel abort a cppi interrupt is generated for a short time by
setting the lowest bit of the TCPPICOMPPTR register. It is then reset
immediately by clearing the bit. When the interrupt handler is run,
it does not detect an interrupt in the TCPPIMSKSR or RCPPIMSKSR
registers and thus exits early without writing the TCPPIEOIR register.
It appears that this inhibits further cppi interrupts until the handler
is called by chance, f.ex. from davinci_interrupt().

By moving the unmasking of the interrupt below the writes to
TCPPICOMPPTR, no interrupt is generated and no write to TCPPIEOIR is
necessary.

USB: musb_gadget: fix STALL handling

The driver incorrectly cancels the mass-storage device CSW request
(which leads to device reset) due to giving back URB at the head of
endpoint's queue after sending each STALL handshake; stop doing that
and start checking for the queue being non-empty before stalling an
endpoint and disallowing stall in such case in musb_gadget_set_halt()
like the other gadget drivers do.

Moreover, the driver starts Rx request despite of the endpoint being
halted -- fix this by moving the SendStall bit check from musb_g_rx()
to rxstate().  And we also sometimes get into rxstate() with DMA still
active after clearing an endpoint's halt (not clear why), so bail out
in this case, similarly to what txstate() does...

While at it, also do the following changes :

- in musb_gadget_set_halt(), remove pointless Tx FIFO flushing (the
  driver does not allow stalling with non-empty Tx FIFO anyway);

- in rxstate(), stop pointlessly zeroing the 'csr' variable;

- in musb_gadget_set_halt(), move the 'done' label to a more proper
  place;

- in musb_g_rx(), eliminate the 'done' label completely...

Alan Stern [Wed, 18 Nov 2009 16:37:15 +0000]
USB: EHCI: don't send Clear-TT-Buffer following a STALL

This patch (as1304) fixes a regression in ehci-hcd.  Evidently some
hubs don't handle Clear-TT-Buffer requests correctly, so we should
avoid sending them when they don't appear to be absolutely necessary.
The reported symptom is that output on a downstream audio device cuts
out because the hub stops relaying isochronous packets.

The patch prevents Clear-TT-Buffer requests from being sent following
a STALL handshake.  In theory a STALL indicates either that the
downstream device sent a STALL or that no matching TT buffer could be
found.  In either case, the transfer is completed and the TT buffer
does not remain busy, so it doesn't need to be cleared.

Also, the patch fixes a minor flaw in the code that actually sends the
Clear-TT-Buffer requests.  Although the pipe direction isn't really
used for control transfers, it should be a Send rather than a Receive.

Staging: hv: Fix vmbus event handler bug

The flag ENABLE_POLLING is always enabled in original Makefile, but
accidently removed during porting to mainline kernel. The patch fixes
this bug which can cause stalled network communication.  Credit needs to
go to Eric Sesterhenn <eric.sesterhenn@lsexperts.de> For pointing out a
typo in the original code as well.

tty/of_serial: add missing ns16550a id

Many boards have a bug-free ns16550 compatible serial port, which we should
register as PORT_16550A. This introduces a new value "ns16550a" for the
compatible property of of_serial to let a firmware choose that model instead
of using the crippled PORT_16550 mode.

Some drivers allow O_NDELAY of a dead port (eg for setserial to work). In that

powerpc: Fix DEBUG_HIGHMEM build break from d4515646699

Code was added to mm/higmem.c that depends on several
kmap types that powerpc does not support.  We add dummy
invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE.

According to list discussion, this fix should not be needed
anymore starting with 2.6.33.  The code is commented to this
effect so hopefully we will remember to remove this.
