[ Upstream commit ddd8d94 ] As we are using cpu_pm to save and restore context, we must also save and restore the GPIO sysconfig register. This is needed because we are not calling PM runtime functions at all with cpu_pm. We need to save the sysconfig on idle as it's value can get reconfigured by PM runtime and can be different from the init time value. Device specific flags like "ti,no-idle-on-init" can affect the init value.

[ Upstream commit 4d09ccc ] Commit 941432d ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. This was based on the observation that the Pine64-LTS has as "push-push" SD card socket, and that the schematic mentions the card detect GPIO. After having received two reports about failing SD card access with that patch, some more research and polls on that subject revealed that there are at least two different versions of the Pine64-LTS out there: - On some boards (including mine) the card detect pin is "stuck" at high, regardless of an microSD card being inserted or not. - On other boards the card-detect is working, but is active-high, by virtue of an explicit inverter circuit, as shown in the schematic. To cover all versions of the board out there, and don't take any chances, let's revert the introduction of the active-low CD GPIO, but let's use the broken-cd property for the Pine64-LTS this time. That should avoid regressions and should work for everyone, even allowing SD card changes now. The SOPine card detect has proven to be working, so let's keep that GPIO in place.

[ Upstream commit 84a24bf ] While this code is executed with the wait_lock held, a reader can acquire the lock without holding wait_lock. The writer side loops checking the value with the atomic_cond_read_acquire(), but only truly acquires the lock when the compare-and-exchange is completed successfully which isn’t ordered. This exposes the window between the acquire and the cmpxchg to an A-B-A problem which allows reads following the lock acquisition to observe values speculatively before the write lock is truly acquired. We've seen a problem in epoll where the reader does a xchg while holding the read lock, but the writer can see a value change out from under it. Writer | Reader -------------------------------------------------------------------------------- ep_scan_ready_list() | |- write_lock_irq() | |- queued_write_lock_slowpath() | |- atomic_cond_read_acquire() | | read_lock_irqsave(&ep->lock, flags); --> (observes value before unlock) | chain_epi_lockless() | | epi->next = xchg(&ep->ovflist, epi); | | read_unlock_irqrestore(&ep->lock, flags); | | | atomic_cmpxchg_relaxed() | |-- READ_ONCE(ep->ovflist); | A core can order the read of the ovflist ahead of the atomic_cmpxchg_relaxed(). Switching the cmpxchg to use acquire semantics addresses this issue at which point the atomic_cond_read can be switched to use relaxed semantics.

[ Upstream commit 9d48015 ] There may be a kernel panic on the Haswell server and the Broadwell server, if the snbep_pci2phy_map_init() return error. The uncore_extra_pci_dev[HSWEP_PCI_PCU_3] is used in the cpu_init() to detect the existence of the SBOX, which is a MSR type of PMON unit. The uncore_extra_pci_dev is allocated in the uncore_pci_init(). If the snbep_pci2phy_map_init() returns error, perf doesn't initialize the PCI type of the PMON units, so the uncore_extra_pci_dev will not be allocated. But perf may continue initializing the MSR type of PMON units. A null dereference kernel panic will be triggered. The sockets in a Haswell server or a Broadwell server are identical. Only need to detect the existence of the SBOX once. Current perf probes all available PCU devices and stores them into the uncore_extra_pci_dev. It's unnecessary. Use the pci_get_device() to replace the uncore_extra_pci_dev. Only detect the existence of the SBOX on the first available PCU device once. Factor out hswep_has_limit_sbox(), since the Haswell server and the Broadwell server uses the same way to detect the existence of the SBOX. Add some macros to replace the magic number.

[ Upstream commit 4b2f1e5 ] The only stepping of Broadwell Xeon parts is stepping 1. Fix the relevant isolation_ucodes[] entry, which previously enumerated stepping 2. Although the original commit was characterized as an optimization, it is also a workaround for a correctness issue. If a PMI arrives between kvm's call to perf_guest_get_msrs() and the subsequent VM-entry, a stale value for the IA32_PEBS_ENABLE MSR may be restored at the next VM-exit. This is because, unbeknownst to kvm, PMI throttling may clear bits in the IA32_PEBS_ENABLE MSR. CPUs with "PEBS isolation" don't suffer from this issue, because perf_guest_get_msrs() doesn't report the IA32_PEBS_ENABLE value.

[ Upstream commit a994edd ] Currently psw_idle does not allocate a stack frame and does not save its r14 and r15 into the save area. Even though this is valid from call ABI point of view, because psw_idle does not make any calls explicitly, in reality psw_idle is an entry point for controlled transition into serving interrupts. So, in practice, psw_idle stack frame is analyzed during stack unwinding. Depending on build options that r14 slot in the save area of psw_idle might either contain a value saved by previous sibling call or complete garbage.

[ Upstream commit 2afeec0 ] The logic in connect() is currently written with the assumption that xenbus_watch_pathfmt() will return an error for a node that does not exist. This assumption is incorrect: xenstore does allow a watch to be registered for a nonexistent node (and will send notifications should the node be subsequently created). As of commit 1f25657 ("xen-netback: remove 'hotplug-status' once it has served its purpose"), this leads to a failure when a domU transitions into XenbusStateConnected more than once. On the first domU transition into Connected state, the "hotplug-status" node will be deleted by the hotplug_status_changed() callback in dom0. On the second or subsequent domU transition into Connected state, the hotplug_status_changed() callback will therefore never be invoked, and so the backend will remain stuck in InitWait. This failure prevents scenarios such as reloading the xen-netfront module within a domU, or booting a domU via iPXE. There is unfortunately no way for the domU to work around this dom0 bug. Fix by explicitly checking for existence of the "hotplug-status" node, thereby creating the behaviour that was previously assumed to exist.
