2018-02-27cfg80211: add missing dependency to CFG80211 suboptionsRomain Naour
New options introduced by the patch this fixes are still enabled even if CFG80211 is disabled. .config: # CONFIG_CFG80211 is not set CONFIG_CFG80211_REQUIRE_SIGNED_REGDB=y CONFIG_CFG80211_USE_KERNEL_REGDB_KEYS=y # CONFIG_LIB80211 is not set When CFG80211_REQUIRE_SIGNED_REGDB is enabled, it selects SYSTEM_DATA_VERIFICATION which selects SYSTEM_TRUSTED_KEYRING that need extract-cert tool. extract-cert needs some openssl headers to be installed on the build machine. Instead of adding missing "depends on CFG80211", it's easier to use a 'if' block around all options related to CFG80211, so do that.

2018-02-27printk: Wake klogd when passing console_lock ownerPetr Mladek
wake_klogd is a local variable in console_unlock(). The information is lost when the console_lock owner using the busy wait added by the commit dbdda842fe96f8932 ("printk: Add console owner and waiter logic to load balance console writes"). The following race is possible: CPU0 CPU1 console_unlock() for (;;) /* calling console for last message */ printk() log_store() log_next_seq++; /* see new message */ if (seen_seq != log_next_seq) { wake_klogd = true; seen_seq = log_next_seq; } console_lock_spinning_enable(); if (console_trylock_spinning()) /* spinning */ if (console_lock_spinning_disable_and_check()) { printk_safe_exit_irqrestore(flags); return; console_unlock() if (seen_seq != log_next_seq) { /* already seen */ /* nothing to do */ Result: Nobody would wakeup klogd. One solution would be to make a global variable from wake_klogd. But then we would need to manipulate it under a lock or so. This patch wakes klogd also when console_lock is passed to the spinning waiter. It looks like the right way to go. Also userspace should have a chance to see and store any "flood" of messages. Note that the very late klogd wake up was a historic solution. It made sense on single CPU systems or when sys_syslog() operations were synchronized using the big kernel lock like in v2.1.113. But it is questionable these days.

2018-02-27mmc: sdhci-pci: Fix S0i3 for Intel BYT-based controllersAdrian Hunter
Tuning can leave the IP in an active state (Buffer Read Enable bit set) which prevents the entry to low power states (i.e. S0i3). Data reset will clear it. Generally tuning is followed by a data transfer which will anyway sort out the state, so it is rare that S0i3 is actually prevented.

2018-02-27gpio: Handle deferred probing in of_find_gpio() properlyChen-Yu Tsai
of_get_named_gpiod_flags() used directly in of_find_gpio() or indirectly through of_find_spi_gpio() or of_find_regulator_gpio() can return -EPROBE_DEFER. This gets overwritten by the subsequent of_find_*_gpio() calls. This patch fixes this by trying of_find_spi_gpio() or of_find_regulator_gpio() only if deferred probing was not requested by the previous of_get_named_gpiod_flags() call.

2018-02-27gpiolib: Keep returning EPROBE_DEFER when we shouldMaxime Ripard
Commits c85823390215 ("gpio: of: Support SPI nonstandard GPIO properties") and 6a537d48461d ("gpio: of: Support regulator nonstandard GPIO properties") have introduced a regression in the way error codes from of_get_named_gpiod_flags are handled. Previously, those errors codes were returned immediately, but the two commits mentioned above are now overwriting the error pointer, meaning that whatever value has been returned will be dropped in favor of whatever the two new functions will return. This might not be a big deal except for EPROBE_DEFER, on which GPIOlib customers will depend on, and that will now be returned as an hard error which means that they will not probe anymore, instead of gently deferring their probe. Since EPROBE_DEFER basically means that we have found a valid property but there was no GPIO controller registered to handle it, fix this issues by returning it as soon as we encounter it.

the free mem space and the lower limit both include two parts: system memory and swap space. For the OOM triggered by TTM, that is the case as below: first swap space is full of swapped out pages and soon system memory also is filled up with ttm pages. and then any memory allocation request will run into OOM. to cover two cases: a. if no swap disk at all or free swap space is under swap mem limit but available system mem is bigger than sys mem limit, allow TTM allocation; b. if the available system mem is less than sys mem limit but free swap space is bigger than swap mem limit, allow TTM allocation. v2: merge two memory limit(swap and system) into one v3: keep original behavior except ttm_opt_ctx->flags with TTM_OPT_FLAG_FORCE_ALLOC v4: always set force_alloc as tx->flags & TTM_OPT_FLAG_FORCE_ALLOC v5: add an attribute for lower_mem_limit v6: set lower_mem_limit as 0 to keep original behavior Signed-off-by: Roger He <Hongbo.He@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
