2020-03-27block: simplify queue allocationChristoph Hellwig
Current make_request based drivers use either blk_alloc_queue_node or blk_alloc_queue to allocate a queue, and then set up the make_request_fn function pointer and a few parameters using the blk_queue_make_request helper. Simplify this by passing the make_request pointer to blk_alloc_queue, and while at it merge the _node variant into the main helper by always passing a node_id, and remove the superfluous gfp_mask parameter. A lower-level __blk_alloc_queue is kept for the blk-mq case. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-27bcache: pass the make_request methods to blk_queue_make_requestChristoph Hellwig
bcache is the only driver not actually passing its make_request methods to blk_queue_make_request, but instead just sets them up manually a little later.

gcc 10 will default to -fno-common, which causes this error at link time: (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here This is because both dtc-lexer as well as dtc-parser define the same global symbol yyloc.

2020-03-27x86/split_lock: Avoid runtime reads of the TEST_CTRL MSRXiaoyao Li
In a context switch from a task that is detecting split locks to one that is not (or vice versa) we need to update the TEST_CTRL MSR. Currently this is done with the common sequence: read the MSR flip the bit write the MSR in order to avoid changing the value of any reserved bits in the MSR. Cache unused and reserved bits of TEST_CTRL MSR with SPLIT_LOCK_DETECT bit cleared during initialization, so we can avoid an expensive RDMSR instruction during context switch.

2020-03-27x86/split_lock: Rework the initialization flow of split lock detectionXiaoyao Li
Current initialization flow of split lock detection has following issues: 1. It assumes the initial value of MSR_TEST_CTRL.SPLIT_LOCK_DETECT to be zero. However, it's possible that BIOS/firmware has set it. 2. X86_FEATURE_SPLIT_LOCK_DETECT flag is unconditionally set even if there is a virtualization flaw that FMS indicates the existence while it's actually not supported. Rework the initialization flow to solve above issues. In detail, explicitly clear and set split_lock_detect bit to verify MSR_TEST_CTRL can be accessed, and rdmsr after wrmsr to ensure bit is cleared/set successfully. X86_FEATURE_SPLIT_LOCK_DETECT flag is set only when the feature does exist and the feature is not disabled with kernel param "split_lock_detect=off" On each processor, explicitly updating the SPLIT_LOCK_DETECT bit based on sld_sate in split_lock_init() since BIOS/firmware may touch it.

2020-03-26net: ks8851-ml: Fix IO operations, againMarek Vasut
This patch reverts 58292104832f ("net: ks8851-ml: Fix 16-bit IO operation") and edacb098ea9c ("net: ks8851-ml: Fix 16-bit data access"), because it turns out these were only necessary due to buggy hardware. This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.

2020-03-26cpufreq: intel_pstate: Simplify intel_pstate_cpu_init()Rafael J. Wysocki
The initial policy value set by intel_pstate_cpu_init() depends on whether or not CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is set, but that is not necessary, because the core will set the policy to "performance" in cpufreq_init_policy() if the default governor is "performance" anyway. Accordingly, change intel_pstate_cpu_init() to always set policy to CPUFREQ_POLICY_POWERSAVE initially to provide a valid fallback value to cpufreq_init_policy() in case the default cpufreq governor is neither "powersave" nor "performance".

git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211 Johannes Berg says: ==================== We have the following fixes: * drop data packets if there's no key for them anymore, after there had been one, to avoid sending them in clear when hostapd removes the key before it removes the station and the packets are still queued * check port authorization again after dequeue, to avoid sending packets if the station is no longer authorized * actually remove the authorization flag before the key so packets are also dropped properly because of this * fix nl80211 control port packet tagging to handle them as packets allowed to go out without encryption * fix NL80211_ATTR_CHANNEL_WIDTH outgoing netlink attribute width (should be 32 bits, not 8) * don't WARN in a CSA scenario that happens on some APs * fix HE spatial reuse element size calculation ==================== Signed-off-by: David S.

2020-03-26mlxsw: spectrum_mr: Fix list iteration in error pathIdo Schimmel
list_for_each_entry_from_reverse() iterates backwards over the list from the current position, but in the error path we should start from the previous position. Fix this by using list_for_each_entry_continue_reverse() instead. This suppresses the following error from coccinelle: drivers/net/ethernet/mellanox/mlxsw//spectrum_mr.c:655:34-38: ERROR: invalid reference to the index variable of the iterator on line 636 Fixes: c011ec1bbfd6 ("mlxsw: spectrum: Add the multicast routing offloading logic") Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
