GCC explicitly does not warn for unused static inline functions for -Wunused-function. The manual states: Warn whenever a static function is declared but not defined or a non-inline static function is unused. Clang does warn for static inline functions that are unused. It turns out that suppressing the warnings avoids potentially complex #ifdef directives, which also reduces LOC. Suppress the warning for clang.

The current wrap implementation has a race issue: it is called outside of the ctx_alloc_lock, and also does not wait for all CPUs to complete the wrap. This means that a thread can get a new context with a new version and another thread might still be running with the same context. The problem is especially severe on CPUs with shared TLBs, like sun4v. I used the following test to very quickly reproduce the problem: - start over 8K processes (must be more than context IDs) - write and read values at a memory location in every process. Very quickly memory corruptions start happening, and what we read back does not equal what we wrote. Several approaches were explored before settling on this one: Approach 1: Move smp_new_mmu_context_version() inside ctx_alloc_lock, and wait for every process to complete the wrap. (Note: every CPU must WAIT before leaving smp_new_mmu_context_version_client() until every one arrives). This approach ends up with deadlocks, as some threads own locks which other threads are waiting for, and they never receive softint until these threads exit smp_new_mmu_context_version_client(). Since we do not allow the exit, deadlock happens. Approach 2: Handle wrap right during mondo interrupt. Use etrap/rtrap to enter into into C code, and issue new versions to every CPU. This approach adds some overhead to runtime: in switch_mm() we must add some checks to make sure that versions have not changed due to wrap while we were loading the new secondary context. (could be protected by PSTATE_IE but that degrades performance as on M7 and older CPUs as it takes 50 cycles for each access). Also, we still need a global per-cpu array of MMs to know where we need to load new contexts, otherwise we can change context to a thread that is going way (if we received mondo between switch_mm() and switch_to() time). Finally, there are some issues with window registers in rtrap() when context IDs are changed during CPU mondo time. The approach in this patch is the simplest and has almost no impact on runtime. We use the array with mm's where last secondary contexts were loaded onto CPUs and bump their versions to the new generation without changing context IDs. If a new process comes in to get a context ID, it will go through get_new_mmu_context() because of version mismatch. But the running processes do not need to be interrupted. And wrap is quicker as we do not need to xcall and wait for everyone to receive and complete wrap.

After a wrap (getting a new context version) a process must get a new context id, which means that we would need to flush the context id from the TLB before running for the first time with this ID on every CPU. But, we use mm_cpumask to determine if this process has been running on this CPU before, and this mask is not reset after a wrap. So, there are two possible fixes for this issue: 1. Clear mm cpumask whenever mm gets a new context id 2. Unconditionally flush context every time process is running on a CPU This patch implements the first solution Signed-off-by: NPavel Tatashin <pasha.tatashin@oracle.com> Reviewed-by: NBob Picco <bob.picco@oracle.com> Reviewed-by: NSteven Sistare <steven.sistare@oracle.com> Signed-off-by: NDavid S.

When a TSB grows beyond its current capacity, a new TSB is allocated and copy_tsb is called to copy entries from the old TSB to the new. A hash shift based on page size is used to calculate the index of an entry in the TSB. copy_tsb has hard coded PAGE_SHIFT in these calculations. However, for huge page TSBs the value REAL_HPAGE_SHIFT should be used. As a result, when copy_tsb is called for a huge page TSB the entries are placed at the incorrect index in the newly allocated TSB. When doing hardware table walk, the MMU does not match these entries and we end up in the TSB miss handling code. This code will then create and write an entry to the correct index in the TSB. We take a performance hit for the table walk miss and recreation of these entries. Pass a new parameter to copy_tsb that is the page size shift to be used when copying the TSB.

Linux SPARC64 limits NR_CPUS to 4064 because init_cpu_send_mondo_info() only allocates a single page for NR_CPUS mondo entries. Thus we cannot use all 4096 CPUs on some SPARC platforms. To fix, allocate (2^order) pages where order is set according to the size of cpu_list for possible cpus. Since cpu_list_pa and cpu_mondo_block_pa are not used in asm code, there are no imm13 offsets from the base PA that will break because they can only reach one page.

stmmac_tso_allocator can fail to set the Last Descriptor bit on a descriptor that actually was the last descriptor. This happens when the buffer of the last descriptor ends up having a size of exactly TSO_MAX_BUFF_SIZE. When the IP eventually reaches the next last descriptor, which actually has the bit set, the DMA will hang. When the DMA hangs, we get a tx timeout, however, since stmmac does not do a complete reset of the IP in stmmac_tx_timeout, we end up in a state with completely hung TX.

Pull libata fixes from Tejun Heo: - Revert of sata_mv devm_ioremap_resource() conversion. It made init fail if there are overlapping resources which led to detection failures on some setups. - A workaround for an Acer laptop which sometimes reports corrupt port map. - Other non-critical fixes. * 'for-4.12-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: libata: fix error checking in in ata_parse_force_one() Revert "ata: sata_mv: Convert to devm_ioremap_resource()" ata: libahci: properly propagate return value of platform_get_irq() ata: sata_rcar: Handle return value of clk_prepare_enable ahci: Acer SA5-271 SSD Not Detected Fix

Sending host command with CMD_WANT_SKB flag demands the release of the response buffer with iwl_free_resp function. The patch adds the memory release in all the relevant places Signed-off-by: NShahar S Matityahu <shahar.s.matityahu@intel.com> Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>

In a previous commit, we removed support for API versions earlier than 22 for these NICs. By mistake, the *_UCODE_API_MIN definitions were set to 17. Fix that. Fixes: 4b87e5af ("iwlwifi: remove support for fw older than -17 and -22") Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>

The iwl_mvm_remove_sta_key() function handles removing a key when the sta doesn't exist anymore. Mistakenly, this was changed to return an error while fixing another bug. If the mvm_sta doesn't exist, we continue normally, but just don't try to remove the igtk key.

We only need to handle d0i3 entry and exit during suspend resume if system_pm is set to IWL_PLAT_PM_MODE_D0I3, otherwise d0i3 entry failures will cause suspend to fail. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=194791Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>

When we want to stop the recording of the firmware debug and restart it later without reloading the firmware we don't need to resend the configuration that comes with host commands. Sending those commands confused the hardware and led to an NMI 0x66. Change the flow as following: * read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL) * clear those registers * wait for the hardware to complete its write to the buffer * get the data * restore the value of those registers (to restart the recording) For early start (where the configuration is already compiled in the firmware), we don't need to set those registers after the firmware has been loaded, but only when we want to restart the recording without having restarted the firmware.

The ucode_loaded check should be under the mutex, since it can otherwise change state after we looked at it and before we got the mutex. Fix that.

Allow working IBSS also when working in DQA mode. This is done by setting it to treat the queues the same as a BSS AP treats the queues.

During d0i3 flow we flush all the queue except from the command queue. Currently, in this flow the command queue is hard coded to 9. In DQA the command queue number has changed from 9 to 0. Fix that. This fixes a problem in runtime PM resume flow.
