 - 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

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.

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

led_class: fix typo in blink API

When I added led_blink_set I had a typo: the return value of the hw
offload is a regular error code that is zero when succesful, and in that
case software emulation should not be used, rather than the other way
around.

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.

The difference is due to vmstat only counting scanning of the inactive

[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.

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

13 years agoarch/tile: handle rt_sigreturn() more cleanly
Chris Metcalf [Tue, 14 Dec 2010 21:07:25 +0000 (16:07 -0500)]
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.

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.
