2010-05-05raid6: fix recovery performance regressionDan Williams
The raid6 recovery code should immediately drop back to the optimized synchronous path when a p+q dma resource is not available. Otherwise we run the non-optimized/multi-pass async code in sync mode. Verified with raid6test (NDISKS=255) Applies to kernels >= 2.6.32. Cc: <stable@kernel.org> Acked-by: NeilBrown <neilb@suse.de> Reported-by: H.

2010-05-05KEYS: Fix RCU handling in key_gc_keyring()David Howells
key_gc_keyring() needs to either hold the RCU read lock or hold the keyring semaphore if it's going to scan the keyring's list. Given that it only needs to read the key list, and it's doing so under a spinlock, the RCU read lock is the thing to use. Furthermore, the RCU check added in e7b0a61b7929632d36cf052d9e2820ef0a9c1bfe is incorrect as holding the spinlock on key_serial_lock is not grounds for assuming a keyring's pointer list can be read safely. Instead, a simple rcu_dereference() inside of the previously mentioned RCU read lock is what we want. Reported-by: Serge E.

2010-05-04i2c: Fix probing of FSC hardware monitoring chipsJean Delvare
Some FSC hardware monitoring chips (Syleus at least) doesn't like quick writes we typically use to probe for I2C chips. Use a regular byte read instead for the address they live at (0x73). These are the only known chips living at this address on PC systems. For clarity, this fix should not be needed for kernels 2.6.30 and later, as we started instantiating the hwmon devices explicitly based on DMI data. Still, this fix is valuable in the following two cases: * Support for recent FSC chips on older kernels. The DMI-based device instantiation is more difficult to backport than the device support itself. * Case where the DMI-based device instantiation fails, whatever the reason. We fall back to probing in that case, so it should work.

If a rename operation is resent to the MDS following an MDS restart, the client does not get a full reply (containing the resulting metadata) back. In that case, a ceph_rename() needs to compensate by doing anything useful that fill_inode() would have, like d_move().

2010-04-30MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jumpWu Zhangjin
The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.

2010-04-30MIPS: Loongson: Add CPU_LOONGSON2F_WORKAROUNDSWu Zhangjin
As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds in the kernel and binutils. This issue has been rectified in Loongson 2F series 2F03 so no workarounds needed. Now that the workarounds [1] adding the the -mfix-loongson2f-nop and -mfix-loongson2f-jump options have been comitted to the binutils the CVS repository), we can add the workarounds in the kernel. The workarounds have no significant side effect on the system but may decrease performance so we control them through a a new CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable it as necessary.

In some cases the mdio bus is not enabled at the time of probing. This prevents anything from working, so we will enable it before trying to use it, and disable it when the driver is removed.

2010-04-30MIPS: Loongson: Fix LOONGSON_ADDRWIN_CFG macro.Arnaud Patard
There's a typo in the LOONGSON_ADDRWIN_CFG macro. The cpu window mmap register address should contain the destination parameters not the source one. This has not been noticed because the code is only using source = destination.
