When caching is disabled on the MN10300 arch, the sys_cacheflush()
function is removed by conditional stuff in the makefiles, but is still
referred to by the syscall table.Provide a null version that just returns 0 when caching is disabled (or
-EINVAL if the arguments are silly).Signed-off-by: David Howells

Tssk. Apparently Al hadn't checked commit c52c2ddc1dfa ("alpha: switch
osf_sigprocmask() to use of sigprocmask()") at all. It doesn't compile.Fixed as per suggestions from Michael Cree.

ahci: fix module refcount breakage introduced by libahci split -
libata depends on scsi_host_template for module reference counting and
sht's should be owned by each low level driver. During libahci split,
the sht was left with libahci.ko leaving the actual low level drivers
not reference counted. This made ahci and ahci_platform always
unloadable even while they're being actively used.Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for
each low level ahci driver.stable: only applicable to 2.6.35.

Commit e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced
a build breakage if CONFIG_SMP is undefined. This commit
fixes the problem.This fix is only a workaround. For a real fix, cpu_sibling_mask() should
be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be
included directly. This fix is currently not possible because asm/smp.h defines
cpu_sibling_mask() unconditionally and is included directly from many source
files.Reported-by: Ingo Molnar

x86: Avoid 'constant_test_bit()' misoptimization due to cast to non-volatile -
Fixes kernel bugzilla #16603
tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write
zero bytes, for example.There is also the problem higher up of how verify_iovec() works. It
wants to prevent the total length from looking like an error return
value.However it does this using 'int', but syscalls return 'long' (and
thus signed 64-bit on 64-bit machines). So it could trigger
false-positives on 64-bit as written. So fix it to use 'long'.Reported-by: Olaf Bonorden

The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a
pktcdvd_device from the global pkt_devs array. The index into this
array is provided directly by the user and is a signed integer, so the
comparison to ensure that it falls within the bounds of this array will
fail when provided with a negative index.This can be used to read arbitrary kernel memory or cause a crash due to
an invalid pointer dereference. This can be exploited by users with
permission to open /dev/pktcdvd/control (on many distributions, this is
readable by group "cdrom").Signed-off-by: Dan Rosenberg

p9_virtio_create will only compare the the channel's tag characters
against the device name till the end of the channel's tag but not till
the end of the device name. This means that if a user defines channels
with the tags foo and foobar then he would mount foo when he requested
foonot and may mount foo when he requested foobar.Thus it is necessary to check both string lengths against each other in
case of a successful partial string match.Signed-off-by: Sven Eckelmann

When the interface is up, using ethtool breaks it because:
a) link is put down but media_timer interval is not shortened to NO_LINK
b) rxtx is stopped but not restartedAlso manual 10baseT-HD (and probably FD too - untested) mode does not work -
the link is forced up, packets are transmitted but nothing is received.
Changing CSR14 value to match documentation (not disabling link check) fixes this.Signed-off-by: Ondrej Zary

When TCP uses FACK algorithm to mark lost packets in
tcp_mark_head_lost(), if the number of packets in the (TSO) skb is
greater than the number of packets that should be marked lost, TCP
incorrectly exits the loop and marks no packets lost in the skb. This
underestimates tp->lost_out and affects the recovery/retransmission.
This patch fargments the skb and marks the correct amount of packets
lost.Signed-off-by: Yuchung Cheng

This patch (commit 690a1f2002a3091bd18a501f46c9530f10481463) added a

already disabled. In particular, putting the device into D3hot is a
pretty bad idea when it was already brought up.Furthermore, all prior callers of the function made sure they're
actually dealing with a PCI device, while the newly added one didn't.In the same spirit, the .get_wol handler shouldn't indicate support
for WOL for non-PCI devices.Signed-off-by: Jan Beulich

The HW by default has RX coalescing on. For iWARP connections, this
causes a 100ms delay in connection establishement due to the ingress
MPA Start message being stalled in HW. So explicitly turn RX
coalescing off when setting up iWARP connections.This was causing very bad performance for NP64 gather operations using
Open MPI, due to the way it sets up connections on larger jobs.Signed-off-by: Steve Wise

The PL310 on the ct-ca9x4 tile for the Versatile Express does not need
to add additional latency when accessing its cache RAMs. Unfortunately,
the boot monitor sets this up for an 8-cycle delay on reads and writes,
resulting in greatly reduced memory performance when the L2 cache is
enabled.This patch sets the L2 RAM latencies to the correct value of 1 cycle
on the ct-ca9x4 tile before enabling the L2 cache.Acked-by: Catalin Marinas
