Using a single list for all userspace devices leads to a dead lock on multiplexed buses in some circumstances (mux chip instantiated from userspace). This is solved by using a separate list for each bus segment. Signed-off-by:

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. This fixes kernel bug #15634: https://bugzilla.kernel.org/show_bug.cgi?id=15634Signed-off-by:

After discovering that a lot of i2c-drivers leave the pointer to their clientdata dangling, it was decided to let the core handle this issue. It is assumed that the core may access the private data after remove() as there are no guarantees for the lifetime of such pointers anyhow (see thread starting at http://lkml.org/lkml/2010/3/21/68) Signed-off-by:

It's useless, since our allocations are already a power of 2. And it was allocated per-instance (not globally), which caused a name collision when we tried to mount a second file system with auth_x enabled. Signed-off-by:Sage Weil <sage@newdream.net>

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(). It also needs to invalidate the dentry (to workaround the vfs_rename_dir() bug) and clear the dir complete flag, just like fill_trace(). Signed-off-by: -

The snap realm split was checking i_snap_realm, not the list_head, to determine if an inode belonged in the new realm. The check always failed, which meant we always moved the inode, corrupting the old realm's list and causing various crashes. Also wait to release old realm reference to avoid possibility of use after free. Signed-off-by: -

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.

With the "Fixups of Loongson2F" patch [1] having been applied to binutils for binutils 2.20.1 we now can use it's time to enable the options provided by the patch to compile the kernel. Without these fixups, the system may hang if the erratum is triggered. For more information on these fixups please refer to the following references.

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.

"MIPS: Calculate proper ebase value for 64-bit kernels" 9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp. f6be75d0 (kernel.org) broke some 64-bit MIPS systems. Before this we were using XKPHYS/cached as ebase and computed the uncached xphsys/unchached address for that area. After that commit ebase became a 32-bit compat address and convert does not work anymore. We now should use CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit. Signed-off-by:

For some combinations of PAGE_SIZE and vmbits, it is possible to have userspace access that are beyond what is covered by the PGD, but within vmbits. Such an access would cause the TLB refill handler to load garbage values for PMD and PTE potentially giving userspace access to parts of the physical address space to which it is not entitled. In the TLB refill hot path, we add a single dsrl instruction so we can check if any bits outside of the range covered by the PGD are set. In the vmalloc side we then separate the bad case from the normal vmalloc case and call tlb_do_page_fault_0 if warranted. This slows us down a bit, but has the benefit of yielding deterministic behavior.

The MIPS implementation of die() forgets to call notify_die() and thus notifiers registered via register_die_notifier() are not called. This results in kgdb not being activated on exceptions. The only subtlety is that notify_die declares its regs argument w/o const, so the const had to be removed from mips die() as well.

Same issues as SD card detection: One of both is always triggering and the handlers take care to shut it up and enable the other. To avoid messages about "unbalanced interrupt enable/disable" they must not be automatically enabled when initally requested. This was not an issue with the db1200_defconfig due to fortunate timings; on a build without network chip support the warnings appear. Signed-off-by:
