2011-12-01ARM: OMAP1: Remove unsafe clock values from omap1_defconfigJanusz Krzysztofik
DPLL1 reprogramming to a different rate is actually blocked inside omap1_select_table_rate(), resulting in the defalut rate of 60 MHz always used instead of the one selected in .config. OTOH, in omap1_defconfig we currently rely on Kconfig options for the supported MHz rates in case of boards which boot with dpll1 not set correctly by their boot loaders. This means that before we allow for reprogramming of dpll1 rate, we should remove all unsafe clock selections from omap1_defconfig, otherwise it will stop booting on boards with imperfect boot loaders, as it would always try to change to 216MHz. Keep only one safe clock rate per each supported xtal frequency, i.e. 60MHZ dpll1 for 12MHz xtal and 182MHz dpll1 for 13MHz xtal. BTW, this change goes into the direction of removing all OMAP1 clock rate options, planned for next merge window.

2011-12-01ARM: OMAP1: Fix reprogramming of DPLL1 for systems that boot at rates below ↵Tony Lindgren
60MHz Commit e9b7086b80c4d9e354f4edc9e280ae85a60df408 (ARM: OMAP: Fix reprogramming of dpll1 rate) fixed a regression for systems that did not rely on bootloader set rates. However, it also introduced a new problem where the rates selected in .config would not take affect as omap1_select_table_rate currently refuses to reprogram DPLL1 if it's already initialized. This was not a problem earlier, as the reprogramming was done earlier with ck_dpll1_p->rate uninitialized. Fix this by forcing the reprogramming on systems booting at rates below 60MHz. Note that the long term fix is to make the rates SoC specific later on. Thanks for Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> for figuring this one out.

2011-12-02fs: Make write(2) interruptible by a fatal signalJan Kara
Currently write(2) to a file is not interruptible by any signal. Sometimes this is desirable, e.g. when you want to quickly kill a process hogging your disk. Also, with commit 499d05ecf990 ("mm: Make task in balance_dirty_pages() killable"), it's necessary to abort the current write accordingly to avoid it quickly dirtying lots more pages at unthrottled rate. This patch makes write interruptible by SIGKILL. We do not allow write to be interruptible by any other signal because that has larger potential of screwing some badly written applications.

RED is useful for high throughput routers, I doubt many linux machines act as such devices. I was considering adding Adaptative RED (Sally Floyd, Ramakrishna Gummadi, Scott Shender), August 2001 In this version, maxp is dynamic (from 1% to 50%), and user only have to setup min_th (target average queue size) (max_th and wq (burst in linux RED) are automatically setup) By the way it seems we have a small bug in red_change() if (skb_queue_empty(&sch->q)) red_end_of_idle_period(&q->parms); First, if queue is empty, we should call red_start_of_idle_period(&q->parms); Second, since we dont use anymore sch->q, but q->qdisc, the test is meaningless. Oh well... [PATCH] sch_red: fix red_change() Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty, we start an idle period, not end it.

2011-12-01ocfs2: avoid unaligned access to dqc_bitmapAkinobu Mita
The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

2011-12-01bridge: master device stuck in no-carrier state forever when in user-stp modeVitalii Demianets
When in user-stp mode, bridge master do not follow state of its slaves, so after the following sequence of events it can stuck forever in no-carrier state: 1) turn stp off 2) put all slaves down - master device will follow their state and also go in no-carrier state 3) turn stp on with bridge-stp script returning 0 (go to the user-stp mode) Now bridge master won't follow slaves' state and will never reach running state. This patch solves the problem by making user-stp and kernel-stp behavior similar regarding master following slaves' states.

2011-12-01Revert "xHCI: reset-on-resume quirk for NEC uPD720200"Sarah Sharp
This reverts commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa. The commit added a reset-on-resume quirk because the NEC chipset stopped responding to commands about 30 minutes after a system resume from suspend. We thought it was a chipset issue, but it turns out that the xHCI driver was zeroing out the link TRB after a successful context restore during resume. The host controller would fall off the command ring sometime later, causing it to not respond to new commands. The link TRB issue has been fixed with commit 158886cd2cf4599e04f9b7e10cb767f5f39b14f1 "xHCI: fix bug in xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's not necessary.

2011-12-01xHCI: fix bug in xhci_clear_command_ring()Andiry Xu
When system enters suspend, xHCI driver clears command ring by writing zero to all the TRBs. However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.

2011-12-01Btrfs: fix meta data raid-repair merge problemJan Schmidt
Commit 4a54c8c16 introduced raid-repair, killing the individual readpage_io_failed_hook entries from inode.c and disk-io.c. Commit 4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to disk-io.c. The raid-repair commit had logic to disable raid-repair, if readpage_io_failed_hook is set. Thus, the readahead commit effectively disabled raid-repair for meta data. This commit changes the logic to always attempt raid-repair when needed and call the readpage_io_failed_hook in case raid-repair fails. This is much more straight forward and should have been like that from the beginning.

It turned out that this is not a good idea, it makes the behaviour of the debuggee dependent on the order of specific ptrace call, e.g. the REGSET_SYSTEM_CALL register set needs to be written last.

The of_irq_init() expects the callback passed by .data of of_device_id return 'int' instead of 'void'. This patch fixes it to have irq_init_cb() return the correct value, and in turn have the secondary interrupt controller (gpio in this case) initialized properly and also eliminate the error message 'of_irq_init: children remain, but no parents' which was overlooked before.

2011-11-30net/core: fix rollback handler in register_netdevice_notifierRongQing.Li

2011-11-30sch_red: fix red_calc_qavg_from_idle_timeEric Dumazet
Since commit a4a710c4a7490587 (pkt_sched: Change PSCHED_SHIFT from 10 to 6) it seems RED/GRED are broken. red_calc_qavg_from_idle_time() computes a delay in us units, but this delay is now 16 times bigger than real delay, so the final qavg result smaller than expected. Use standard kernel time services since there is no need to obfuscate them. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-30bonding: only use primary address for ARPHenrik Saavedra Persson
Only use the primary address of the bond device for master_ip. This will prevent changing the ARP source address in Active-Backup mode whenever a secondry address is added to the bond device.
