2010-10-08ARM: 6428/1: add cpu_idle_wait() to support CPUidle on SMP systems.Kevin Hilman3-0/+24
In order for CPUidle to work on SMP systems, an implementation of cpu_idle_wait() is needed. This patch duplicates the x86 implementation of cpu_idle_wait() for ARM.

2010-10-08ARM: 6429/1: Check for is_smp for tlb_ops and cache_ops broadcastTony Lindgren1-11/+17
Broadcast should not be needed when running SMP kernel on UP systems. Also, this fixes an undefined instruction for SMP_ON_UP on earlier ARM cores without the extended CPUID_EXT_MMFR3 register. Signed-off-by: Tony Lindgren <[email protected]> Signed-off-by: Russell King <[email protected]>
2010-10-04ARM: 6405/1: Handle __flush_icache_all for CONFIG_SMP_ON_UPTony Lindgren4-27/+77
Do this by adding flush_icache_all to cache_fns for ARMv6 and 7. As flush_icache_all may neeed to be called from flush_kern_cache_all, add it as the first entry in the cache_fns. Note that now we can remove the ARM_ERRATA_411920 dependency to !SMP so it can be selected on UP ARMv6 processors, such as omap2.

2010-10-04ARM: Allow SMP kernels to boot on UP systemsRussell King14-102/+237
UP systems do not implement all the instructions that SMP systems have, so in order to boot a SMP kernel on a UP system, we need to rewrite parts of the kernel. Do this using an 'alternatives' scheme, where the kernel code and data is modified prior to initialization to replace the SMP instructions, thereby rendering the problematical code ineffectual. We use the linker to generate a list of 32-bit word locations and their replacement values, and run through these replacements when we detect a UP system.

2010-10-04ARM: Simplify SMP/SCU/TWD dependenciesRussell King1-10/+7
All platforms which currently support SMP also support the ARM SCU and ARM TWD blocks, so it's pointless to make these config symbols conditional on the platform symbols which SMP is already conditional on. Signed-off-by: Russell King <[email protected]>

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).

2010-09-28ahci: fix module refcount breakage introduced by libahci splitTejun Heo4-14/+24
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.

2010-09-28hwmon (coretemp): Fix build breakage if SMP is undefinedGuenter Roeck1-0/+1
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.

2010-09-27tcp: Fix >4GB writes on 64-bit.David S. Miller3-4/+5
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'.

2010-09-27Fix pktcdvd ioctl dev_minor range checkDan Rosenberg1-1/+1
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").

2010-09-27net/9p: Mount only matching virtio channelsSven Eckelmann1-1/+2
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 <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2010-09-27de2104x: fix ethtoolOndrej Zary1-2/+5
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 restarted Also manual 10baseT-HD (and probably FD too - untested) mode does not work - the link is forced up, packets are transmitted but nothing is received.

2010-09-27tcp: fix TSO FACK loss marking in tcp_mark_head_lostYuchung Cheng1-1/+2
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.

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 <[email protected]> Signed-off-by: David S. Miller <[email protected]>
