In commit 022d00ee ("ASoC: lpass-platform: Fix broken pcm data usage") the stream specific information initialization was broken, with the dma channel information not being initialized if there was no alloc_dma_channel() helper function. Before that, the DMA channel number was implicitly initialized to zero because the backing store was allocated with devm_kzalloc(). When the init code was rewritten, that implicit initialization was lost, and gcc rightfully complains about an uninitialized variable being used.

This reverts commit bfd8d3f2. It turns out that this flushes things much too aggressiverly, and causes lines to break up when the system logger races with new continuation lines being printed. There's a pending patch to make printk() flushing much more straightforward, but it's too invasive for 4.9, so in the meantime let's just not make the system message logging flush continuation lines. They'll be flushed by the final newline anyway. Suggested-by: NPetr Mladek <pmladek@suse.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

This is a static checker warning, not something I'm desperately concerned about. But snprintf() returns the number of bytes that would have been copied if there were space. We really care about the number of bytes that actually were copied so we should use scnprintf() instead. It probably won't overrun, and in that case we may as well just use sprintf() but these sorts of things make static checkers and code reviewers happier.

Booting an EFI mixed mode kernel has been crashing since commit: e37e43a4 ("x86/mm/64: Enable vmapped stacks (CONFIG_HAVE_ARCH_VMAP_STACK=y)") The user-visible effect in my test setup was the kernel being unable to find the root file system ramdisk. This was likely caused by silent memory or page table corruption. Enabling CONFIG_DEBUG_VIRTUAL=y immediately flagged the thunking code as abusing virt_to_phys() because it was passing addresses that were not part of the kernel direct mapping. Use the slow version instead, which correctly handles all memory regions by performing a page table walk.

(The last is enabled on 32-bit on a PAE build.) However, its value comes from __pa() which is basically doing pointer arithmetic and checking, and returns unsigned long as it is the native pointer width. So let's use an unsigned long too.

The ns->lba_shift assumes its value to be the logarithmic of the LA size. A previous patch duplicated the lba_shift calculation into lightnvm. It prematurely also subtracted a 512byte shift, which commonly is applied per-command. The 512byte shift being subtracted twice led to data loss when restoring the logical to physical mapping table from device and when issuing I/O commands using rrpc. Fix offset by removing the 512byte shift subtraction when calculating lba_shift.

Pull power management fixes from Rafael Wysocki: "These fix two bugs in error code paths in the PM core (system-wide suspend of devices), a device reference leak in the boot-time suspend test code and a cpupower utility regression from the 4.7 cycle. Specifics: - Prevent the PM core from attempting to suspend parent devices if any of their children, whose suspend callbacks were invoked asynchronously, have failed to suspend during the "late" and "noirq" phases of system-wide suspend of devices (Brian Norris). - Prevent the boot-time system suspend test code from leaking a reference to the RTC device used by it (Johan Hovold). - Fix cpupower to use the return value of one of its library functions correctly and restore the correct behavior of it when used for setting cpufreq tunables broken during the 4.7 development cycle (Laura Abbott)" * tag 'pm-4.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / sleep: don't suspend parent when async child suspend_{noirq, late} fails PM / sleep: fix device reference leak in test_suspend cpupower: Correct return type of cpu_power_is_cpu_online() in cpufreq-set
