mm: dont clear PG_uptodate on truncate/invalidate
Brian Wang reported that a FUSE filesystem exported through NFS could
return I/O errors on read. This was traced to splice_direct_to_actor()
returning a short or zero count when racing with page invalidation.
However this is not FUSE or NFSD specific, other filesystems (notably
NFS) also call invalidate_inode_pages2() to purge stale data from the
cache.
If this happens while such pages are sitting in a pipe buffer, then
splice(2) from the pipe can return zero, and read(2) from the pipe can
return ENODATA.
The zero return is especially bad, since it implies end-of-file or
disconnected pipe/socket, and is documented as such for splice. But
returning an error for read() is also nasty, when in fact there was no
error (data becoming stale is not an error).
The same problems can be triggered by "hole punching" with
madvise(MADV_REMOVE).
Fix this by not clearing the PG_uptodate flag on truncation and
invalidation.

PNP: fix formatting of dbg_pnp_show_resources() output
Each resource should be printed on its own line, so start snprintf'ing
at the beginning of the buffer every time through the loop.
Also, use scnprintf() rather than snprintf() when building up the
buffer to print. scnprintf() returns the number of characters actually
written into the buffer (not including the trailing NULL).
snprintf() returns the number of characters that *would be* written,
assuming everything would fit in the buffer. That's nice if we want to
resize the buffer to make sure everything fits, but in this case, I
just want to keep from overflowing the buffer, and it's OK if the
output is truncated.
Using snprintf() meant that my "len" could grow to be more than the
the buffer size, which makes "sizeof(buf) - len" negative, which causes
this alarming WARN_ON:

rtl8187: Fix lockups due to concurrent access to config routine
Some users of the RTL8187B have experienced difficulties since commit 49292d56352a6ab90d04c3448dd8b6106dfef2d6 that introduced the power
management wext hooks. This difficulty has not made much sense until
it was realized that it was possible for mac80211 to make a call to the
config routine while that routine was already being executed. On this
device, it is necessary to loopback the TX when changing channels. Unless
this is properly restored, the device will lockup. A mutex now protects
the device state, and the private data in several places.
The problem was found by Herton Ronaldo Krzesinski <herton@mandriva.com.br>,
who also suggested this type of fix.

I believe that there is a problem with that patch --- it
(inadvertantly) removes an extra line of code, that used to set the
DATABYTE_COUNT field.
This patch reinstates that line, and with it my card works again.

The sequence counter can be accessed in IRQ context,

rt2x00: rt61pci needs another millisecond after firmware upload
After the hardware has indicated the firmware upload has completed
and the device is ready, we should wait another millisecond to
make sure the device is really ready to continue.
Without this timout, bringing the interface down and up again will
fail due to incorrect register initialization.

rt2x00: Fix partial antenna configuration
The if-statement to determine the new TX/RX antenna
configuration was incomplete. It lacks the general
else-clause when the antenna wasn't changed.
This is a correct event, since it can occur when only
one of the antenna's has been changed or when the new
configuration is being forced (like when the interface
has just been added).

rt2x00: Fix access permissions on debugfs files
Although most rt2x00 debugfs files don't contain

it is better to set the access permissions to root only.
This will be required when HW crypto is implemented,
because it could be possible to read the HW key from
the registers.

rfkill: query EV_SW states when rfkill-input (re)?connects to a input device
Every time a new input device that is capable of one of the
rfkill EV_SW events (currently only SW_RFKILL_ALL) is connected to
rfkill-input, we must check the states of the input EV_SW switches
and take action. Otherwise, we will ignore the initial switch state.
We also need to re-check the states of the EV_SW switches after
a device that was under an exclusive grab is released back to us,
since we got no input events from that device while it was grabbed.
