2012-12-01sfc: Remove confusing MMIO functionsBen Hutchings
efx_writed_table() uses a step of 16 bytes but efx_readd_table() uses a step of 4 bytes. Why are they different? Firstly, register access is asymmetric: - The EVQ_RPTR table and RX_INDIRECTION_TBL can (or must?) be written as dwords even though they have a step size of 16 bytes, unlike most other CSRs. - In general, a read of any width is valid for registers, so long as it does not cross register boundaries. There is also no latching behaviour in the BIU, contrary to rumour. We write to the EVQ_RPTR table with efx_writed_table() but never read it back as it's write-only. We write to the RX_INDIRECTION_TBL with efx_writed_table(), but only read it back for the register dump, where we use efx_reado_table() as for any other table with step size of 16. We read MC_TREG_SMEM with efx_readd_table() for the register dump, but normally read and write it with efx_readd() and efx_writed() using offsets calculated in bytes. Since these functions are trivial and have few callers, it's clearer to open-code them at the call sites. While we're at it, update the comments on the BIU behaviour again.

2012-12-01sfc: Really disable flow control while flushingBen Hutchings
Receiving pause frames can block TX queue flushes. Earlier changes work around this by reconfiguring the MAC during flushes for VFs, but during flushes for the PF we would only change the fc_disable counter. Unless the MAC is reconfigured for some other reason during the flush (which I would not expect to happen) this had no effect at all. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-11-30x86, fpu: Avoid FPU lazy restore after suspendVincent Palatin
When a cpu enters S3 state, the FPU state is lost. After resuming for S3, if we try to lazy restore the FPU for a process running on the same CPU, this will result in a corrupted FPU context. Ensure that "fpu_owner_task" is properly invalided when (re-)initializing a CPU, so nobody will try to lazy restore a state which doesn't exist in the hardware. Tested with a 64-bit kernel on a 4-core Ivybridge CPU with eagerfpu=off, by doing thousands of suspend/resume cycles with 4 processes doing FPU operations running. Without the patch, a process is killed after a few hundreds cycles by a SIGFPE.

2012-11-30KVM: x86: Emulate IA32_TSC_ADJUST MSRWill Auld
CPUID.7.0.EBX[1]=1 indicates IA32_TSC_ADJUST MSR 0x3b is supported Basic design is to emulate the MSR by allowing reads and writes to a guest vcpu specific location to store the value of the emulated MSR while adding the value to the vmcs tsc_offset. In this way the IA32_TSC_ADJUST value will be included in all reads to the TSC MSR whether through rdmsr or rdtsc. This is of course as long as the "use TSC counter offsetting" VM-execution control is enabled as well as the IA32_TSC_ADJUST control. However, because hardware will only return the TSC + IA32_TSC_ADJUST + vmsc tsc_offset for a guest process when it does and rdtsc (with the correct settings) the value of our virtualized IA32_TSC_ADJUST must be stored in one of these three locations. The argument against storing it in the actual MSR is performance. This is likely to be seldom used while the save/restore is required on every transition. IA32_TSC_ADJUST was created as a way to solve some issues with writing TSC itself so that is not an option either. The remaining option, defined above as our solution has the problem of returning incorrect vmcs tsc_offset values (unless we intercept and fix, not done here) as mentioned above. However, more problematic is that storing the data in vmcs tsc_offset will have a different semantic effect on the system than does using the actual MSR. This is illustrated in the following example: The hypervisor set the IA32_TSC_ADJUST, then the guest sets it and a guest process performs a rdtsc. In this case the guest process will get TSC + IA32_TSC_ADJUST_hyperviser + vmsc tsc_offset including IA32_TSC_ADJUST_guest. While the total system semantics changed the semantics as seen by the guest do not and hence this will not cause a problem.

2012-11-30KVM: x86: Add code to track call origin for msr assignmentWill Auld
In order to track who initiated the call (host or guest) to modify an msr value I have changed function call parameters along the call path. The specific change is to add a struct pointer parameter that points to (index, data, caller) information rather than having this information passed as individual parameters. The initial use for this capability is for updating the IA32_TSC_ADJUST msr while setting the tsc value. It is anticipated that this capability is useful for other tasks.

2012-11-30net: move inet_dport/inet_num in sock_commonEric Dumazet
commit 68835aba4d9b (net: optimize INET input path further) moved some fields used for tcp/udp sockets lookup in the first cache line of struct sock_common. This patch moves inet_dport/inet_num as well, filling a 32bit hole on 64 bit arches and reducing number of cache line misses in lookups. Also change INET_MATCH()/INET_TW_MATCH() to perform the ports match before addresses match, as this check is more discriminant. Remove the hash check from MATCH() macros because we dont need to re validate the hash value after taking a refcount on socket, and use likely/unlikely compiler hints, as the sk_hash/hash check makes the following conditional tests 100% predicted by cpu. Introduce skc_addrpair/skc_portpair pair values to better document the alignment requirements of the port/addr pairs used in the various MATCH() macros, and remove some casts. The namespace check can also be done at last. This slightly improves TCP/UDP lookup times. IP/TCP early demux needs inet->rx_dst_ifindex and TCP needs inet->min_ttl, lets group them together in same cache line. With help from Ben Hutchings & Joe Perches. Idea of this patch came after Ling Ma proposal to move skc_hash to the beginning of struct sock_common, and should allow him to submit a final version of his patch. My tests show an improvement doing so.

2012-11-30context_tracking: New context tracking susbsystemFrederic Weisbecker
Create a new subsystem that probes on kernel boundaries to keep track of the transitions between level contexts with two basic initial contexts: user or kernel. This is an abstraction of some RCU code that use such tracking to implement its userspace extended quiescent state. We need to pull this up from RCU into this new level of indirection because this tracking is also going to be used to implement an "on demand" generic virtual cputime accounting.

2012-11-30wireless: allow Atheros card to not depend on ath.koVladimir Kondratiev
There are 2 different things: - sub-menu for "Atheros Wireless cards" family - module ath.ko with common Atheros code Until now, they both used to depend on the same Kconfig variable ATH_COMMON. Thus, being "Atheros card" and "depending on ath.ko" was the same. To allow module to belong to the "Atheros Wireless cards" family but not use ath.ko, 2 conditions above need to be separated. So, this patch introduce new Kconfig variable ATH_CARDS for belonging to the "Atheros Wireless Cards" family; while ATH_COMMON becomes hidden variable to express dependency on common Atheros code in ath.ko. Modules that depend on this common code now express it by setting ATH_COMMON. Right now, ath6kl do not depend on common code and thus do not set ATH_COMMON.
