Past evidence with system hangs and hsds tie WaForceEnableNonCoherent and WaDisableHDCInvalidation to WaForceContextSaveRestoreNonCoherent.

2016-07-08xen/acpi: allow xen-acpi-processor driver to load on Xen 4.7Jan Beulich
As of Xen 4.7 PV CPUID doesn't expose either of CPUID[1].ECX[7] and CPUID[0x80000007].EDX[7] anymore, causing the driver to fail to load on both Intel and AMD systems. Doing any kind of hardware capability checks in the driver as a prerequisite was wrong anyway: With the hypervisor being in charge, all such checking should be done by it. If ACPI data gets uploaded despite some missing capability, the hypervisor is free to ignore part or all of that data. Ditch the entire check_prereq() function, and do the only valid check (xen_initial_domain()) in the caller in its place.

2016-07-08xenbus: don't bail early from xenbus_dev_request_and_reply()Jan Beulich
xenbus_dev_request_and_reply() needs to track whether a transaction is open. For XS_TRANSACTION_START messages it calls transaction_start() and for XS_TRANSACTION_END messages it calls transaction_end(). If sending an XS_TRANSACTION_START message fails or responds with an an error, the transaction is not open and transaction_end() must be called. If sending an XS_TRANSACTION_END message fails, the transaction is still open, but if an error response is returned the transaction is closed. Commit 027bd7e89906 ("xen/xenbus: Avoid synchronous wait on XenBus stalling shutdown/restart") introduced a regression where failed XS_TRANSACTION_START messages were leaving the transaction open. This can cause problems with suspend (and migration) as all transactions must be closed before suspending. It appears that the problematic change was added accidentally, so just remove it.

2016-07-06iommu/amd: Fix unity mapping initialization raceJoerg Roedel
There is a race condition in the AMD IOMMU init code that causes requested unity mappings to be blocked by the IOMMU for a short period of time. This results on boot failures and IO_PAGE_FAULTs on some machines. Fix this by making sure the unity mappings are installed before all other DMA is blocked.

We verify "u_cmd.outsize" and "u_cmd.insize" but we need to make sure that those values have not changed between the two copy_from_user() calls. Otherwise it could lead to a buffer overflow. Additionally, cros_ec_cmd_xfer() can set s_cmd->insize to a lower value. We should use the new smaller value so we don't copy too much data to the user.

2016-07-05ACPICA: Namespace: Fix namespace/interpreter lock orderingLv Zheng
There is a lock order issue in acpi_load_tables(). The namespace lock is held before holding the interpreter lock. With ACPI_MUTEX_DEBUG enabled in the kernel, this is printed to the log during boot: [ 0.885699] ACPI Error: Invalid acquire order: Thread 405884224 owns [ACPI_MTX_Namespace], wants [ACPI_MTX_Interpreter] (20160422/utmutex-263) [ 0.885881] ACPI Error: Could not acquire AML Interpreter mutex (20160422/exutils-95) [ 0.893846] ACPI Error: Mutex [0x0] is not acquired, cannot release (20160422/utmutex-326) [ 0.894019] ACPI Error: Could not release AML Interpreter mutex (20160422/exutils-133) The issue has been introduced by the following commit: Commit: 2f38b1b16d9280689e5cfa47a4c50956bf437f0d ACPICA Commit: bfe03ffcde8ed56a7eae38ea0b188aeb12f9c52e Subject: ACPICA: Namespace: Fix a regression that MLC support triggers dead lock in dynamic table loading Which fixed a deadlock issue for acpi_ns_load_table() in acpi_ex_add_table() but didn't take care of the lock order in acpi_ns_load_table() correctly. Originally (before the above commit), ACPICA used the namespace/interpreter locks in the following 2 key code paths: 1. Table loading: acpi_ns_load_table L(Namespace) acpi_ns_parse_table acpi_ns_one_complete_parse U(Namespace) 2. Object evaluation: acpi_ns_evaluate L(Interpreter) acpi_ps_execute_method U(Interpreter) acpi_ns_load_table L(Namespace) U(Namespace) acpi_ev_initialize_region L(Namespace) U(Namespace) address_space.setup L(Namespace) U(Namespace) address_space.handler L(Namespace) U(Namespace) acpi_os_wait_semaphore acpi_os_acquire_mutex acpi_os_sleep L(Interpreter) U(Interpreter) During runtime, while acpi_ns_evaluate is called, the lock order is always Interpreter -> Namespace. In turn, the problematic commit acquires the locks in the following order: 3. Table loading: acpi_ns_load_table L(Namespace) acpi_ns_parse_table L(Interpreter) acpi_ns_one_complete_parse U(Interpreter) U(Namespace) To fix the lock order issue, move the interpreter lock to acpi_ns_load_table() to ensure the lock order correctness: 4. Table loading: acpi_ns_load_table L(Interpreter) L(Namespace) acpi_ns_parse_table acpi_ns_one_complete_parse U(Namespace) U(Interpreter) However, this doesn't fix the current design issues related to the namespace lock. For example, we can notice that in acpi_ns_evaluate(), outside of acpi_ns_load_table(), the namespace objects may be created by the named object creation control methods. And the creation of the method-owned namespace objects are not locked by the namespace lock. This patch doesn't try to fix such kind of existing issues.

2016-07-05bonding: fix enslavement slave link notificationsAviv Heller
Currently, link notifications are not sent by bond_set_slave_link_state() upon enslavement if the slave is enslaved when up. This happens because slave->link default init value is 0, which is the same as BOND_LINK_UP, resulting in bond_set_slave_link_state() ignoring this transition. This patch sets the default value of slave->link to BOND_LINK_NOCHANGE, assuring it will count as a state transition and thus trigger notification logic.
