The REN bit puts the transmitter in high-impedance state. The driver recognizes that data is to be received by checking whether the rx_buf of a transfer is non-NULL. Commit 3ecd37edaa2a ("spi: bcm2835: enable dma modes for transfers meeting certain conditions") subsequently broke 3-wire support because it set the SPI_MASTER_MUST_RX flag which causes spi_map_msg() to replace rx_buf with a dummy buffer if it is NULL. As a result, rx_buf is *always* non-NULL if DMA is enabled. Reinstate 3-wire support by not only checking whether rx_buf is non-NULL, but also checking that it is not the dummy buffer.

[PATCH] arm64: cpufeature: Fix feature comparison for CTR_EL0.{CWG, ERG}

by Will Deacon

commit 147b9635e6347104b91f48ca9dca61eb0fbf2a54 upstream. If CTR_EL0.{CWG,ERG} are 0b0000 then they must be interpreted to have their architecturally maximum values, which defeats the use of FTR_HIGHER_SAFE when sanitising CPU ID registers on heterogeneous machines. Introduce FTR_HIGHER_OR_ZERO_SAFE so that these fields effectively saturate at zero.

To avoid using the uninitialized struct page, immediately return with KPF_RESERVED at the beginning of stable_page_flags() if the page is reserved by ZONE_DEVICE driver.

[PATCH 4.19] Revert "initramfs: free initrd memory if opening /initrd.image fails"

by Stephen Boyd

This reverts commit 25511676362d8f7d4b8805730a3d29484ceab1ec in the 4.19 stable trees. From what I can tell this commit doesn't do anything to improve the situation, mostly just reordering code to call free_initrd() from one place instead of many. In doing that, it causes free_initrd() to be called even in the case when there isn't an initrd present. That leads to virtual memory bugs that manifest on arm64 devices. The fix has been merged upstream in commit 5d59aa8f9ce9 ("initramfs: don't free a non-existent initrd"), but backporting that here is more complicated because the patch is stacked upon this patch being reverted along with more patches that rewrites the logic in this area. Let's just revert the patch from the stable tree instead of trying to backport a collection of fixes to get the final fix from upstream.

[PATCH V4 1/2] cpufreq: schedutil: Don't skip freq update when limits change

by Viresh Kumar

To avoid reducing the frequency of a CPU prematurely, we skip reducing the frequency if the CPU had been busy recently. This should not be done when the limits of the policy are changed, for example due to thermal throttling. We should always get the frequency within the new limits as soon as possible. Trying to fix this by using only one flag, i.e. need_freq_update, can lead to a race condition where the flag gets cleared without forcing us to change the frequency at least once. And so this patch introduces another flag to avoid that race condition.
