Previously we used to get EXPORT_SYMBOL and friends from module.h but we moved away from that since module.h largely includes the entire header space one way or another. As most users just wanted the simple export related macros, they were spun off into a separate new header -- export.h Update the docs to reflect that.

It seems there are about 80 new, but undocumented addtions at the top level Documentation directory. This fixes up the top level 00-INDEX by adding new entries and deleting a couple orphans.

Sure, it's just the pointer value we use, but the coverity checker complains about a use-after-free bug and it really does seem cleaner to delay freeing until we are entirely done with the memory. So, rearrange the code to move the kfree() later untill we are completely done. Trivial and harmless, but nice IMHO.

With lazy interrupt, we always call __check_irq_replaysome with decrementers_next_tb to check if we need to replay timer interrupt. So in hotplug case we also need to set decrementers_next_tb as MAX to make sure __check_irq_replay don't replay timer interrupt when return as we expect, otherwise we'll trap here infinitely.

commit f96972f2 "kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()" added a call to disable_nonboot_cpus() on kernel_restart(), which tries to shutdown all the CPUs except the first one. The issue with the PA Semi, is that it does not support CPU hotplug. When the call is made to __cpu_down(), it calls the notifiers CPU_DOWN_PREPARE, and then tries to take the CPU down. One of the notifiers to the CPU hotplug code, is the cpufreq. The DOWN_PREPARE will call __cpufreq_remove_dev() which calls cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O that is used by an interrupt that goes off constantly (system_reset_common, but it goes off during normal system operations too). I'm not sure exactly what this interrupt does. Running a simple function trace, you can see it goes off quite a bit: # tracer: function # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | <idle>-0 [001] 1558.859363: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.860112: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861109: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [001] 1558.861361: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861437: .pasemi_system_reset_exception <-.system_reset_exception When the region is unmapped, the system crashes with: Disabling non-boot CPUs ...

The IOMMU may stop processing page translations due to a perceived lack of credits for writing upstream peripheral page service request (PPR) or event logs. If the L2B miscellaneous clock gating feature is enabled the IOMMU does not properly register credits after the log request has completed, leading to a potential system hang. BIOSes are supposed to disable L2B micellaneous clock gating by setting L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b. This patch corrects that for those which do not enable this workaround.

dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum offload, ..), but it can also be put in a dm9601 compatible mode, allowing us to reuse the existing driver.

While sctp handling a duplicate COOKIE-ECHO and the action is 'Association restart', sctp_sf_do_dupcook_a() will processing the unexpected COOKIE-ECHO for peer restart, but it does not set the association state to SCTP_STATE_ESTABLISHED, so the association could stuck in SCTP_STATE_SHUTDOWN_PENDING state forever. This violates the sctp specification: RFC 4960 5.2.4. Handle a COOKIE ECHO when a TCB Exists Action A) In this case, the peer may have restarted. ..... After this, the endpoint shall enter the ESTABLISHED state. To resolve this problem, adding a SCTP_CMD_NEW_STATE cmd to the command list before SCTP_CMD_REPLY cmd, this will set the restart association to SCTP_STATE_ESTABLISHED state properly and also avoid I-bit being set in the DATA chunk header when COOKIE_ACK is bundled with DATA chunks.

There are more types of IP addresses that may appear in ARP packets that we don't want to process. While some of these should never appear in sane ARP packets, a 0.0.0.0 source is used for duplicate address detection and thus seen quite often.

The callers of batadv_dat_snoop_incoming_arp_reply() assume the skb has been freed when it returns true; fix this by calling kfree_skb before returning as it is done in batadv_dat_snoop_incoming_arp_request().
