Will Deacon [Wed, 23 Apr 2014 16:52:52 +0000 (17:52 +0100)]
word-at-a-time: avoid undefined behaviour in zero_bytemask macro
The asm-generic, big-endian version of zero_bytemask creates a mask of
bytes preceding the first zero-byte by left shifting ~0ul based on the
position of the first zero byte.
Unfortunately, if the first (top) byte is zero, the output of
prep_zero_mask has only the top bit set, resulting in undefined C
behaviour as we shift left by an amount equal to the width of the type.
As it happens, GCC doesn't manage to spot this through the call to fls(),
but the issue remains if architectures choose to implement their shift
instructions differently.
An example would be arch/arm/ (AArch32), where LSL Rd, Rn, #32 results
in Rd == 0x0, whilst on arch/arm64 (AArch64) LSL Xd, Xn, #64 results in
Xd == Xn.
Rather than check explicitly for the problematic shift, this patch adds
an extra shift by 1, replacing fls with __fls. Since zero_bytemask is
never called with a zero argument (has_zero() is used to check the data
first), we don't need to worry about calling __fls(0), which is
undefined.

This merges the patch to fix possible loss of dirty bit on munmap() or

have the unmapped/unneeded page in their TLBs, their writes to the page
could possibly get lost if a third CPU raced with the TLB flush and did

Admittedly, if you unmap() or madvice(DONTNEED) an area _while_ another

"A slighlty large fix for a subtle issue in the CPU hotplug code of

Setting interrupt affinity to a not online cpu is prohibited and
therefor the timer interrupt ends up on the wrong cpu, which leads to
nasty complications.
The SoC folks tried to hack around that in the SoC code in some more
than nasty ways. The proper solution is to have a way to enforce the
affinity setting to a not online cpu. The core patch to the genirq
code provides that facility and the follow up patches make use of it
in the GIC interrupt controller and the exynos timer driver.
The change to the core code has no implications to existing users,

staging/lustre/clio: replace semaphore with mutex
According https://www.kernel.org/doc/Documentation/mutex-design.txt:
- the mutex subsystem is slightly faster and has better scalability
for contended workloads. In terms of 'ops per CPU cycle', the
semaphore kernel performed 551 ops/sec per 1% of CPU time used,
while the mutex kernel performed 3825 ops/sec per 1% of CPU time
used - it was 6.9 times more efficient.
- there are no fastpath tradeoffs, the mutex fastpath is just as
tight as the semaphore fastpath. On x86, the locking fastpath is
2 instructions.
- 'struct mutex' semantics are well-defined and are enforced if
CONFIG_DEBUG_MUTEXES is turned on. Semaphores on the other hand
have virtually no debugging code or instrumentation.
One more benefit of mutex is optimistic spinning. It try to spin for
acquisition when there are no pending waiters and the lock owner is
currently running on a (different) CPU. The rationale is that if the
lock owner is running, it is likely to release the lock soon.
This significantly reduce amount of context switches when locked
region is small and we have high contention.

stagaing/lustre: Improve statahead debug messages
The statahead debug messages include the pid of the current

lustre log messages contain the pid), and sometimes downright
misleading. For instance the messages would say something like
"stopping statahead thread 3446". One would probably think
that 3446 is the pid of the process that is being stopped,
but in fact it was the pid of the caller issuing the stop signal.
We remove all superfluous pids from the messages.
Next we have the ll_statahead_thread() and the ll_agl_thread() record
their respective pids in their respective ptlrpc_thread structures.
This allows to print the pid of the thread that we are trying to
stop (which is actually useful info) from other threads, such as those

stop signal will now have been lost. Deadlock ensues.
We also partly improve the sai reference counting, because a race exists
where the ll_stop_statahead thread can drop the default reference, and
the statahead thread can exit and drop its reference as well. With no
references on the sai, the final put will poison and free the buffer. The
original do_statahead_enter() function may then continue to access
the buffer after it is freed because it did not take a reference of its

staging/lustre: Limit reply buffer size
When allocating a reply buffer for the striping information don't
assume the unlikely worst case. Instead, assume the common case
and size the buffer based on the observed default ea/cookie size.
The default size is initialized to a single stripe and allowed to
grow up to an entire page if needed. This means that for smallish
filesystems (less than ~21 OSTs) where the worst case striping
information can fit in a single page there is effectively no
change. Only for larger filesystem will the default be less than
the maximum. This has a number of advantages.
* By limiting the default reply buffer size we avoid always
vmalloc()'ing the buffer because it exceeds four pages in size
and instead kmalloc() it. This prevents the client from
thrashing on the global vmalloc() spin lock.
* A reply buffer of exactly the right size (no larger) is allocated
in the overflow case. These larger reply buffers are still
unlikely to exceed the 16k limit where a vmalloc() will occur.
* Saves memory in the common case. Wide striped files exceeded
the default are expected to be the exception.
The reason this patch works is because the ptlrpc layer is smart
enough to reallocate the reply buffer when an overflow occurs.
Therefore the client doesn't have to drop the incoming reply and
send a new request with a larger reply buffer.
It's also worth mentioning that the reply buffer always contains
a significant amount of extra padding because they are rounded up
to the nearest power of two. This means that even files striped
wider than the default have a good chance of fitting in the
allocated reply buffer.
Also remove client eadatasize check in mdt xattr packing because
as said above client can handle -EOVERFLOW.

staging/lustre: restore __GFP_WAIT flag to memalloc calls
In Lustre 2.4, the flags passed to the memory allocation functions are
translated from CFS enumeration values types to the kernel GFP
values by calling cfs_alloc_flags_to_gfp(). This function adds
__GFP_WAIT to all flags except CFS_ALLOC_ATOMIC. In 2.5, when
the cfs wrappers were dropped, cfs_alloc_flags_to_gfp() was
removed and the CFS_ALLOC_xxxx was simply replaced with __GFP_xxxx.
This means that most memory allocation calls are missing the
__GFP_WAIT flag. The result is that Lustre experiences more ENOMEM
errors, many of which the higher levels of Lustre do not handle
robustly.
Notes GFP_NOFS = __GFP_WAIT | __GFP_IO. So the patch replaces
__GFP_IO with GFP_NOFS.
Patch does not add __GFP_WAIT to GFP_IOFS. GFP_IOFS was not used in
Lustre 2.4 so it has never been used with __GFP_WAIT.

staging/lustre/ptlrpc: don't try to recover no_recov connection
If a connection has been stopped with ptlrpc_pinger_del_import() and
marked obd_no_recov, don't reconnect in ptlrpc_disconnect_import() if
the import is already disconnected. Otherwise, without the pinger it
will just wait there indefinitely for the reconnection that will never
happen.
Put the obd_no_recov check inside ptlrpc_import_in_recovery() so that
any threads waiting on the connection to recover would also be broken
out of their sleep if obd_no_recov is set.

Merge tag 'pm+acpi-3.15-rc3' of git://git./linux/kernel/git/rafael/linux-pm
Pull ACPI and power management fixes from Rafael Wysocki:
"These include a fix for a recent ACPI regression related to device
notifications, intel_idle fix related to IvyTown support, fix for a
buffer size issue in ACPICA, PM core fix related to the "freeze" sleep
state, four fixes for various types of breakage in cpufreq drivers, a
PNP workaround for a wrong memory region size in ACPI tables, and a
fix and cleanup for the ACPI tools Makefile.
Specifics:
- Fix for broken ACPI notifications on some systems caused by a
recent ACPI hotplug commit that blocked the propagation of unknown
type notifications to device drivers inadvertently.
- intel_idle fix to make the IvyTown C-states handling (added
recently) work as intended which now is broken due to missing
braces. From Christoph Jaeger.
- ACPICA fix to make it allocate buffers of the right sizes for the
Generic Serial Bus operation region access. From Lv Zheng.
- PM core fix unblocking cpuidle before entering the "freeze" sleep
state which causes that state to be able to actually save more
energy than runtime idle.
- Configuration and build fixes for the highbank and powernv cpufreq
drivers from Kefeng Wang and Srivatsa S Bhat.
- Coccinelle warning fix related to error pointers for the unicore32
cpufreq driver from Duan Jiong.
- Integer overflow fix for the ppc-corenet cpufreq driver from Geert
Uytterhoeven.
- Workaround for BIOSes that don't report the entire Intel MCH area
in their ACPI tables from Bjorn Helgaas.
- ACPI tools Makefile fix and cleanup from Thomas Renninger"
