git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: - Recent commits modifying the lists of C-states in the intel_idle driver introduced bugs leading to crashes on some systems. Two fixes from Jiang Liu. - The ACPI AC driver should receive all types of notifications, but recent change made it ignore some of them. Fix from Alexander Mezin. - intel_pstate's validity checks for MSRs it depends on are not sufficient to catch the lack of support in nested KVM setups, so they are extended to cover that case. From Dirk Brandewie. - NEC LZ750/LS has a botched up _BIX method in its ACPI tables, so our ACPI battery driver needs a quirk for it. From Lan Tianyu. - The tpm_ppi driver sometimes leaks memory allocated by acpi_get_name(). Fix from Jiang Liu. * tag 'pm+acpi-3.13-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: intel_idle: close avn_cstates array with correct marker Revert "intel_idle: mark states tables with __initdata tag" ACPI / Battery: Add a _BIX quirk for NEC LZ750/LS intel_pstate: Add X86_FEATURE_APERFMPERF to cpu match parameters.

2014-01-08parisc: Ensure full cache coherency for kmap/kunmapJohn David Anglin3-46/+6
Helge Deller noted a few weeks ago problems with the AIO support on parisc. This change is the result of numerous iterations on how best to deal with this problem. The solution adopted here is to provide full cache coherency in a uniform manner on all parisc systems. This involves calling flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on kunmap operations. As a result, the copy_user_page() and clear_user_page() functions can be removed and the overall code is simpler. The change ensures that both userspace and kernel aliases to a mapped page are invalidated and flushed. This is necessary for the correct operation of PA8800 and PA8900 based systems which do not support inequivalent aliases. With this change, I have observed no cache related issues on c8000 and rp3440. It is now possible for example to do kernel builds with "-j64" on four way systems. On systems using XFS file systems, the patch recently posted by Mikulas Patocka to "fix crash using XFS on loopback" is needed to avoid a hang caused by an uninitialized lock passed to flush_dcache_page() in the page struct.

2014-01-08clk: clk-divider: fix divisor > 255 bugJames Hogan1-1/+1
Commit 6d9252bd9a4bb (clk: Add support for power of two type dividers) merged in v3.6 added the _get_val function to convert a divisor value to a register field value depending on the flags. However it used the type u8 for the div field, causing divisors larger than 255 to be masked and the resultant clock rate to be too high. E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This was masked to 238 (0xee) resulting in a frequency of 103.26KHz.

The only BIOS on record that needs the 14 offset has a bios major version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18 offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the bios major version, look at the BMP version. BIOSes with BMP version 0 do not contain a detectable script, so always return 0 for them.

Jani for co-maintainer! Jani has been a really active bug-scrubber in the past few months. I've asked him whether he wants to do this in a more official capacity and he agreed. I've already chatted with Dave and Jesse and they support this. Note that everyone can't now just relax because "Jani will do all the bug scrubbing" - au contraire expect more nagging and poking now that we have more bandwidth. Longer-term the plan is to share more of the maintainer duties, but we need to fix up the infrastructure a bit first (like moving the git repo to a common location).

2014-01-06bridge: use spin_lock_bh() in br_multicast_set_hash_maxCurt Brune1-2/+2
br_multicast_set_hash_max() is called from process context in net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function. br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock), which can deadlock the CPU if a softirq that also tries to take the same lock interrupts br_multicast_set_hash_max() while the lock is held . This can happen quite easily when any of the bridge multicast timers expire, which try to take the same lock. The fix here is to use spin_lock_bh(), preventing other softirqs from executing on this CPU. Steps to reproduce: 1. Create a bridge with several interfaces (I used 4). 2. Set the "multicast query interval" to a low number, like 2. 3. Enable the bridge as a multicast querier. 4. Repeatedly set the bridge hash_max parameter via sysfs. # brctl addbr br0 # brctl addif br0 eth1 eth2 eth3 eth4 # brctl setmcqi br0 2 # brctl setmcquerier br0 1 # while true ; do echo 4096 > /sys/class/net/br0/bridge/hash_max; done Signed-off-by: Curt Brune <[email protected]> Signed-off-by: Scott Feldman <[email protected]> Signed-off-by: David S.

As 32019e651c6fce ("ipv6: Do not leave router anycast address for /127 prefixes.") shows we also may not leave them, because we could accidentally remove an anycast address the user has allocated or got added via another prefix.

2014-01-06hso: fix handling of modem port SERIAL_STATE notificationsDan Williams1-2/+11
The existing serial state notification handling expected older Option devices, having a hardcoded assumption that the Modem port was always USB interface #2. That isn't true for devices from the past few years. hso_serial_state_notification is a local cache of a USB Communications Interface Class SERIAL_STATE notification from the device, and the USB CDC specification (section 6.3, table 67 "Class-Specific Notifications") defines wIndex as the USB interface the event applies to. For hso devices this will always be the Modem port, as the Modem port is the only port which is set up to receive them by the driver. So instead of always expecting USB interface #2, instead validate the notification with the actual USB interface number of the Modem port.

With arm:allmodconfig, building the Teles PCI driver fails with telespci.c:294:2: error: #error "not running on big endian machines now" Similar, building the driver for HFC PCI-Bus cards fails with hfc_pci.c:1647:2: error: #error "not running on big endian machines now" Remove the big endian cpp check from both drivers to fix the build errors.

2014-01-06ext4: fix bigalloc regressionEric Whitney1-1/+1
Commit f5a44db5d2 introduced a regression on filesystems created with the bigalloc feature (cluster size > blocksize). It causes xfstests generic/006 and /013 to fail with an unexpected JBD2 failure and transaction abort that leaves the test file system in a read only state. Other xfstests run on bigalloc file systems are likely to fail as well. The cause is the accidental use of a cluster mask where a cluster offset was needed in ext4_ext_map_blocks().

When *only* the default RXQ is used, the RSS policy must be disabled so that all IP and no-IP traffic is placed into the default RXQ. If not, IP traffic is dropped. Also, issue the RSS_CONFIG cmd only if FW advertises RSS capability for the interface.

2014-01-05net: 6lowpan: fix lowpan_header_create non-compression memcpy callDaniel Borkmann1-1/+1
In function lowpan_header_create(), we invoke the following code construct: struct ipv6hdr *hdr; ... hdr = ipv6_hdr(skb); ... if (...) memcpy(hc06_ptr + 1, &hdr->flow_lbl[1], 2); else memcpy(hc06_ptr, &hdr, 4); Where the else path of the condition, that is, non-compression path, calls memcpy() with a pointer to struct ipv6hdr *hdr as source, thus two levels of indirection. This cannot be correct, and likely only one level of pointer was intended as source buffer for memcpy() here.

2014-01-05bnx2x: fix VLAN configuration for VFs.Yuval Mintz5-112/+174
If the hypervisor configures a vlan for the VF via the PF, the expected result is that only packets tagged by said vlan will be received by the VF (and that vlan will be silently removed). Due to an incorrect manipulation of vlan filters in the driver, the VF can receive untagged traffic even if the hypervisor configured some vlan for it. This patch corrects the behaviour.

2014-01-05bnx2x: fix AFEX memory overflowYuval Mintz1-1/+4
There are 2 different (related) flows in the slowpath configuration that utilize the same pointer and cast it to different structs; This is obviously incorrect as the intended allocated memory is that of the smaller struct, possibly causing the flow utilizing the larger struct to corrupt other slowpath configuration. Since both flows are exclusive, set the allocated memory to be a union of both structs.
