29c185e Paul Mundt 24 December 2010, 03:08:30 UTC nommu: Provide stubbed alloc/free_vm_area() implementation. Now that these have been introduced in to the vmalloc API, sync up the nommu side of things. At present we don't deal with VMAs as such, so for the time being these will simply BUG() out. In the future it should be possible to support this interface by layering on top of the vm_regions. Signed-off-by: Paul Mundt <lethal@linux-sh.org> 24 December 2010, 03:08:30 UTC

44658a1 Andres Salomon 21 December 2010, 21:04:52 UTC cs5535-gpio: handle GPIO regs where higher (clear) bits are set The default for non-READ_BACK GPIO regs is to have the clear bits set; this means that our original errata fix was too simplistic. This changes it to the following behavior: - when setting GPIOs, ignore the higher order bits (they're for clearing, we don't need to care about them). - when clearing GPIOs, keep all the bits, but unset (via XOR) the lower order bit that negates the clear bit that we care about. That is, if we're clearing GPIO 26 (val = 0x04000000), we first XOR what's currently in the register with 0x0400 (GPIO 26's SET bit), and then OR that with the GPIO 26's CLEAR bit.

4be2c95 Jeff Mahoney 22 December 2010, 01:24:30 UTC taskstats: pad taskstats netlink response for aligment issues on ia64 The taskstats structure is internally aligned on 8 byte boundaries but the layout of the aggregrate reply, with two NLA headers and the pid (each 4 bytes), actually force the entire structure to be unaligned. This causes the kernel to issue unaligned access warnings on some architectures like ia64. Unfortunately, some software out there doesn't properly unroll the NLA packet and assumes that the start of the taskstats structure will always be 20 bytes from the start of the netlink payload. Aligning the start of the taskstats structure breaks this software, which we don't want. So, for now the alignment only happens on architectures that require it and those users will have to update to fixed versions of those packages. Space is reserved in the packet only when needed. This ifdef should be removed in several years e.g. 2012 once we can be confident that fixed versions are installed on most systems. We add the padding before the aggregate since the aggregate is already a defined type. Commit 85893120 ("delayacct: align to 8 byte boundary on 64-bit systems") previously addressed the alignment issues by padding out the pid field. This was supposed to be a compatible change but the circumstances described above mean that it wasn't. This patch backs out that change, since it was a hack, and introduces a new NULL attribute type to provide the padding. Padding the response with 4 bytes avoids allocating an aligned taskstats structure and copying it back. Since the structure weighs in at 328 bytes, it's too big to do it on the stack.

4e06fd1 Will Newton 22 December 2010, 01:24:29 UTC include/linux/unaligned: pack the whole struct rather than just the field The current packed struct implementation of unaligned access adds the packed attribute only to the field within the unaligned struct rather than to the struct as a whole. This is not sufficient to enforce proper behaviour on architectures with a default struct alignment of more than one byte. For example, the current implementation of __get_unaligned_cpu16 when compiled for arm with gcc -O1 -mstructure-size-boundary=32 assumes the struct is on a 4 byte boundary so performs the load of the 16bit packed field as if it were on a 4 byte boundary: __get_unaligned_cpu16: ldrh r0, [r0, #0] bx lr Moving the packed attribute to the struct rather than the field causes the proper unaligned access code to be generated: __get_unaligned_cpu16: ldrb r3, [r0, #0] @ zero_extendqisi2 ldrb r0, [r0, #1] @ zero_extendqisi2 orr r0, r3, r0, asl #8 bx lr Signed-off-by: Will Newton <will.newton@gmail.com> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 23 December 2010, 03:43:34 UTC

f06328d Prasad Joshi 22 December 2010, 01:24:20 UTC logfs: fix "Kernel BUG at readwrite.c:1193" This happens when __logfs_create() tries to write a new inode to the disk which is full. __logfs_create() associates the transaction pointer with inode. During the logfs_write_inode() function call chain this transaction pointer is moved from inode to page->private using function move_inode_to_page (do_write_inode() -> inode_to_page() -> move_inode_to_page) When the write inode fails, the transaction is aborted and iput is called on the failed inode. During delete_inode the same transaction pointer associated with the page is getting used. Thus causing kernel BUG. The patch checks for error in write_inode() and restores the page->private to NULL.

Both values were "right" depending on how you look at it. The difference is due to vmstat only counting scanning of the inactive list towards pages scanned. The analysis script for the tracepoint counts active and inactive list yielding a far higher value than vmstat. The resulting scanning/reclaim ratio looks much worse.

d8cc7fd Jarod Wilson 15 December 2010, 22:20:55 UTC [media] mceusb: fix inverted mask inversion logic As it turns out, somewhere along the way, we managed to invert the meaning of the tx_mask_inverted flag. Looking back over the old lirc driver, tx_mask_inverted was set to 0 if the device was in tx_mask_list. Now we have a tx_mask_inverted flag set to 1 for all the devices that were in the list, and set tx_mask_inverted to that flag value, which is actually the opposite of what we used to set, causing set_tx_mask to use the wrong mask setting option. Since there seem to be more devices with inverted masks than not (using the original device as the baseline for inverted vs. normal), lets just call the ones currently marked as inverted normal instead, and flip the if/else actions that key off of the inverted flag. Note: the problem only cropped up if a call to set_tx_mask was made, if no mask was set, the device would work just fine, which is why this managed to slip though w/o getting noticed until now. Tested successfully by myself and Dennis Gilmore.

The leak if we try to read an invalid length is the main concern because it could be triggered over and over. If the copy_to_user() failed, then the original code returned the number of bytes remaining. read() is supposed to be the opposite way, where we return the number of bytes copied. I changed it to just return -EFAULT on errors. Also I changed the debug output from "-EFAULT" to just "<fail>" because it isn't -EFAULT necessarily. And since we go though that path if the length is invalid now, there was another debug print that I removed.

Rather it creates it as virtual device. As a result, udev cannot use the USB device information to create persistent device names for event and lirc devices associated with the rc device. Not having persistent device names makes it more difficult to make use of the devices in userspace as their names can change.

2ee95db Jarod Wilson 12 November 2010, 22:49:04 UTC [media] mceusb: fix keybouce issue after parser simplification Something I failed to notice while testing the mceusb RLE buffer decoding simplification patches was that we were getting an extra event from the previously pressed key. As was pointed out to me on irc by Maxim, this is actually due to using ir_raw_event_store_with_filter without having set up a timeout value. The hardware has a timeout value we're now reading and storing, which properly enables the transition to idle in the raw event storage process, and makes IR decode behave correctly w/o keybounce. Also remove no-longer-used ir_raw_event struct from mceusb_dev struct and add as-yet-unused enable flags for carrier reports and learning mode, which I'll hopefully start wiring up sooner than later. While looking into that, found evidence that 0x9f 0x15 responses are only non-zero when the short-range learning sensor is used, so correct the debug spew message, and then suppress it when using the standard long-range sensor.

1cd50f2 Jarod Wilson 09 November 2010, 21:41:03 UTC [media] mceusb: fix up reporting of trailing space We were storing a bunch of spaces at the end of each signal, rather than a single long space. The in-kernel decoders were actually okay with this, but lirc isn't. As suggested by David Härdeman, switch to storing samples using ir_raw_event_store_with_filter, which auto-merges the consecutive space samples for us. This also allows us to bypass having to store rawir samples in our device struct, further simplifying the buffer parsing state machine. Both in-kernel decoders and lirc are happy again with this change. Also included in this patch is proper parsing of 0x9f 0x01 commands, the removal of some magic number usage and some printk spew fixups.

81711ce Chris Metcalf 14 December 2010, 21:07:25 UTC arch/tile: handle rt_sigreturn() more cleanly The current tile rt_sigreturn() syscall pattern uses the common idiom of loading up pt_regs with all the saved registers from the time of the signal, then anticipating the fact that we will clobber the ABI "return value" register (r0) as we return from the syscall by setting the rt_sigreturn return value to whatever random value was in the pt_regs for r0. However, this breaks in our 64-bit kernel when running "compat" tasks, since we always sign-extend the "return value" register to properly handle returned pointers that are in the upper 2GB of the 32-bit compat address space. Doing this to the sigreturn path then causes occasional random corruption of the 64-bit r0 register. Instead, we stop doing the crazy "load the return-value register" hack in sigreturn. We already have some sigreturn-specific assembly code that we use to pass the pt_regs pointer to C code. We extend that code to also set the link register to point to a spot a few instructions after the usual syscall return address so we don't clobber the saved r0. Now it no longer matters what the rt_sigreturn syscall returns, and the pt_regs structure can be cleanly and completely reloaded.

bc4cf2b Chris Metcalf 14 December 2010, 20:57:49 UTC arch/tile: handle CLONE_SETTLS in copy_thread(), not user space Previously we were just setting up the "tp" register in the new task as started by clone() in libc. However, this is not quite right, since in principle a signal might be delivered to the new task before it had its TLS set up. (Of course, this race window still exists for resetting the libc getpid() cached value in the new task, in principle. But in any case, we are now doing this exactly the way all other architectures do it.) This change is important for 2.6.37 since the tile glibc we will be submitting upstream will not set TLS in user space any more, so it will only work on a kernel that has this fix. It should also be taken for 2.6.36.x in the stable tree if possible. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Cc: stable <stable@kernel.org> 17 December 2010, 21:56:50 UTC
