fix regression introduced in 8.3.3:
commit a9b17323f2875f5d9b132c2b476a750bf44b10c7
Author: Lars Ellenberg <lars.ellenberg@linbit.com>
Date: Wed Aug 12 15:18:33 2009 +0200
out-of-spinlock completion of master bio
: (bio_rw(bio) == READA)
? read_completed_with_error
: read_ahead_completed_with_error;
is obviously not what was intended.
No one noticed because of
* page-cache at work,
* local RAIDs
Impact:
Failed local READs are not retried remotely,
but errored to upper layers, causing filesystems
to remount read-only, or worse.

The only difference between FPU and SIMD exceptions is where the

the discrepency introduced by commit adf77bac, which fixed FPU
but not SIMD.

The cache flush denied error is an erratum on some AMD 486 clones. If an invd
instruction is executed in userspace, the processor calls exception 19 (13 hex)
instead of #GP (13 decimal). On cpus where XMM is not supported, redirect
exception 19 to do_general_protection(). Also, remove die_if_kernel(), since
this was the last user.

Since commit b2a731aa5c, dns323_init() is
setting the power led gpio direction with gpio_direction_output() but
doesn't request the gpio before (which is not permitted by the gpio
layer afaik). This behaviour is triggering a WARN() at boot time.

Frequently when using PPPoE with an interface MTU greater than 1500,
the skb is likely to be non-linear. If the skb needs to be passed to
pppd then the skb data must be read correctly.
The previous commit fixes an issue with accidentally sending skbs
to pppd based on an invalid read of the protocol type. When that
error occurred pppd was reading invalid skb data too.

In ppp_input(), PPP_PROTO(skb) may refer to invalid data in the skb.
If this happens and (proto >= 0xc000 || proto == PPP_CCPFRAG) then
the packet is passed directly to pppd.
This occurs frequently when using PPPoE with an interface MTU
greater than 1500 because the skb is more likely to be non-linear.
The next 2 bytes need to be pulled in ppp_input(). The pull of 2
bytes in ppp_receive_frame() has been removed as it is no longer
required.

When IBSS is fixed to a frequency, it can still
scan to try to find the right BSSID. This makes
sense if the BSSID isn't also fixed, but it need
not scan all channels -- just one is sufficient.
Make it do that by moving the scan setup code to
ieee80211_request_internal_scan() and include
a channel variable setting.
Note that this can be further improved to start
the IBSS right away if both frequency and BSSID
are fixed.

This allows enabling TX and disabling both TX and
RX aggregation sessions manually in debugfs. It is
very useful for debugging session initiation and
teardown problems since with this you don't have
to force a lot of traffic to get aggregation and
thus have less data to analyse.
Also, to debug mac80211 code itself, make hwsim
"support" aggregation sessions. It will still just
transfer the frame, but go through the setup and
teardown handshakes.

This driver uses the core orinoco modules for the bulk of
the functionality. The low level hermes routines (for local bus
cards) are replaced, the driver supplies its own ndo_xmit_start
function, and locking is done with the _bh variant.
Some recent functionality is not available to the USB cards yet
(firmware loading and WPA).

Local bus and USB drivers will need to do locking differently.
The original orinoco_usb patches had a boolean variable controlling
whether spin_lock_bh was used, or irq based locking. This version
provides wrappers for the lock functions and the drivers specify the
functions pointers needed.
This will introduce a performance penalty, but I'm not expecting it to
be noticable.

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().

We can get old message seq #'s after a tcp reconnect for stateful sessions
(i.e., the MDS). If we get a higher seq #, that is an error, and we

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

Don't send the report type as part of the data, this prevents the
controller from going into the operational state at all.
This is completely equivalent to what the code originally meant to accomplish:
as per in net/bluetooth/hidp/core.c::hidp_output_raw_report(), by using
HID_FEATURE_REPORT here, what will be actually sent is
(HIDP_TRANS_SET_REPORT | HIDP_DATA_RTYPE_FEATURE) which is exactly 0x53.

The current perf code implicitly assumes SAMPLE_RAW means tracepoints
are being used, but doesn't check for that. It happily records the
TRACE_INFO even if SAMPLE_RAW is used without tracepoints, but when the
perf data is read it won't go any further when it finds TRACE_INFO but
no tracepoints, and displays misleading errors.
This adds a check for both in perf-record, and won't record TRACE_INFO
unless both are true. This at least allows perf report -D to dump raw
events, and avoids triggering a misleading error condition in perf
trace. It doesn't actually enable the non-tracepoint raw events to be
displayed in perf trace, since perf trace currently only deals with
tracepoint events.
