In commit ae91d60b, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The Coccinelle semantic patch that makes this change is as follows: // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

mpic_msgrs has type struct mpic_msgr **, not struct mpic_msgr *, so the elements of the array should have pointer type, not structure type. The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The Coccinelle semantic patch that makes the first change is as follows: // <smpl> @disable sizeof_type_expr@ type T; T **x; @@ x = <+...sizeof( - T + *x )...+> // </smpl> Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>

The CoreNet Coherency Fabric is part of the memory subsystem on some Freescale QorIQ chips. It can report coherency violations (e.g. due to misusing memory that is mapped noncoherent) as well as transactions that do not hit any local access window, or which hit a local access window with an invalid target ID.

Erratum A-008139 can cause duplicate TLB entries if an indirect entry is overwritten using tlbwe while the other thread is using it to do a lookup. Work around this by using tlbilx to invalidate prior to overwriting. To avoid the need to save another register to hold MAS1 during the workaround code, TID clearing has been moved from tlb_miss_kernel_e6500 until after the SMT section.

The general idea is that each core will release all of its threads into the secondary thread startup code, which will eventually wait in the secondary core holding area, for the appropriate bit in the PACA to be set. The kick_cpu function pointer will set that bit in the PACA, and thus "release" the core/thread to boot. We also need to do a few things that U-Boot normally does for CPUs (like enable branch prediction).

This ensures that all MSR definitions are consistently unsigned long, and that MSR_CM does not become 0xffffffff80000000 (this is usually harmless because MSR is 32-bit on booke and is mainly noticeable when debugging, but still I'd rather avoid it).

Virtualized environments may expose a e6500 dual-threaded core as two single-threaded e6500 cores. Take advantage of this and get rid of the tlb lock and the trap-causing tlbsx in the htw miss handler by guarding with CPU_FTR_SMT, as it's already being done in the bolted tlb1 miss handler. As seen in the results below, measurements done with lmbench random memory access latency test running under Freescale's Embedded Hypervisor, there is a ~34% improvement.

Commit 82d86de2 "TLB lock recursive" introduced a bug whereby cpu 0 uses the same value for "lock held" as is used to indicate that the lock is free. This means that cpu 1 can acquire the lock whenever it wants, regardless of whether cpu 0 has it locked, which in turn means we can get duplicate TLB entries. Add one to the CPU value to ensure we do not use zero as a "lock held" value. Signed-off-by: Scott Wood <scottwood@freescale.com> Reported-by: Ed Swarthout <ed.swarthout@freescale.com>

Previously TID was being cleared before the tlbsx, but not after. This can lead to a multiway hit between a TLB entry with TID=0 (previously inserted when PID=0) and a TLB entry with TID!=0 that matches PID. This can theoretically result in undefined behavior, though we probably get lucky due to the details of the overlap. It also results in the inability to use multihit detection to detect other conflicting TLB entries, as well as poorer TLB utilization due to duplicating kernel TLB entries. Rather than try to patch up MAS1 after tlbsx, the entire value is saved/restored as with MAS2. I observed a slight improvement in TLB miss performance with this patch applied.

This reverts commit e1edf18b. This patch was a misguided attempt at fixing offb for LE ppc64 kernels on BE qemu but is just wrong ... it breaks real LE/LE setups, LE with real HW, and existing mixed endian systems that did the fight thing with the appropriate device-tree property. Bad reviewing on my part, sorry. The right fix is to either make qemu change its endian when the guest changes endian (working on that) or to use the existing foreign endian support.

Commit 3fd091e7 ("[SCTP]: Remove multiple levels of msecs to jiffies conversions.") has silently changed permissions for rto_alpha and rto_beta knobs from 0644 to 0444. The purpose of this was to discourage users from tweaking rto_alpha and rto_beta knobs in production environments since they are key to correctly compute rtt/srtt. RFC4960 under section 6.3.1. RTO Calculation says regarding rto_alpha and rto_beta under rule C3 and C4: [...] C3) When a new RTT measurement R' is made, set RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'| and SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R' Note: The value of SRTT used in the update to RTTVAR is its value before updating SRTT itself using the second assignment. After the computation, update RTO <- SRTT + 4 * RTTVAR. C4) When data is in flight and when allowed by rule C5 below, a new RTT measurement MUST be made each round trip. Furthermore, new RTT measurements SHOULD be made no more than once per round trip for a given destination transport address. There are two reasons for this recommendation: First, it appears that measuring more frequently often does not in practice yield any significant benefit [ALLMAN99]; second, if measurements are made more often, then the values of RTO.Alpha and RTO.Beta in rule C3 above should be adjusted so that SRTT and RTTVAR still adjust to changes at roughly the same rate (in terms of how many round trips it takes them to reflect new values) as they would if making only one measurement per round-trip and using RTO.Alpha and RTO.Beta as given in rule C3. However, the exact nature of these adjustments remains a research issue. [...] While it is discouraged to adjust rto_alpha and rto_beta and not further specified how to adjust them, the RFC also doesn't explicitly forbid it, but rather gives a RECOMMENDED default value (rto_alpha=3, rto_beta=2). We have a couple of users relying on the old permissions before they got changed. That said, if someone really has the urge to adjust them, we could allow it with a warning in the log.

Geert reported issues regarding checksum complete and UDP. The logic introduced in commit 7e3cead5 ("net: Save software checksum complete") is not correct. This patch: 1) Restores code in __skb_checksum_complete_header except for setting CHECKSUM_UNNECESSARY. This function may be calculating checksum on something less than skb->len. 2) Adds saving checksum to __skb_checksum_complete. The full packet checksum 0..skb->len is calculated without adding in pseudo header. This value is saved in skb->csum and then the pseudo header is added to that to derive the checksum for validation. 3) In both __skb_checksum_complete_header and __skb_checksum_complete, set skb->csum_valid to whether checksum of zero was computed. This allows skb_csum_unnecessary to return true without changing to CHECKSUM_UNNECESSARY which was done previously. 4) Copy new csum related bits in __copy_skb_header.

Name the unnamed union as u in order to fix build failure" Let's do this instead: there is only one place in the entire tree that steps into this breakage. Anon structs and unions work in older gcc versions; as the matter of fact, we have those in the tree - see e.g. struct ieee80211_tx_info in include/net/mac80211.h What doesn't work is handling their initializers: struct { int a; union { int b; char c; }; } x[2] = {{.a = 1, .c = 'a'}, {.a = 0, .b = 1}}; is the obvious syntax for initializer, perfectly fine for C11 and handled correctly by gcc-4.7 or later. Earlier versions, though, break on it - declaration is fine and so's access to fields (i.e. x[0].c = 'a'; would produce the right code), but members of the anon structs and unions are not inserted into the right namespace. Tellingly, those older versions will not barf on struct {int a; struct {int a;};}; - looks like they just have it hacked up somewhere around the handling of . and -> instead of doing the right thing. The easiest way to deal with that crap is to turn initialization of those fields (in the only place where we have such initializer of iov_iter) into plain assignment.
