Hi, please consider applying the following two patches from v4.9.y to v4.4.y. fe5844365ec6 ("Backport minimal compiler_attributes.h to support GCC 9") 2c34c215c102 ("include/linux/module.h: copy __init/__exit attrs to init/cleanup_module") (upstream commit a6e60d84989f) ... to enable compiling v4.4.y with gcc 9.x. This already works for the most part, but alpha:allmodconfig and arm:allmodconfig fail to compile. The above two patches fix the problem. Thanks, Guenter

Since no instructions were being patched, no cache maintenance was needed. However, later in be0f272bfc83 ("arm64: ftrace: emit ftrace-mod.o contents through code") this code was reworked to output the trampoline instructions directly into the PLT entry but, unfortunately, the necessary cache maintenance was overlooked. Add a call to __flush_icache_range() after writing the new trampoline instructions but before patching in the branch to the trampoline.

Backport request for bcb44433bba5 ("dm: disable DISCARD if the underlying storage no longer supports it")

by Salvatore Bonaccorso

Hi In Debian bug https://bugs.debian.org/934331 ran into issues which match the upstream commit bcb44433bba5 ("dm: disable DISCARD if the underlying storage no longer supports it"). This commit was CC'ed to stable, but only got applied in v5.0.8 (and later on backported by Ben Hutchings to v3.16.72). Mike, I have not checked how easily that would be for older stable versions, but can the backport be considered for versions down to 4.9? Apparently Ben did succeed with some changes needed. To 4.19 it should apply with a small conflict in drivers/md/dm-core.h AFAICS. Regards, Salvatore

[PATCH] phy: qcom-qmp: Correct ready status, again

by Bjorn Andersson

Despite extensive testing of 885bd765963b ("phy: qcom-qmp: Correct READY_STATUS poll break condition") I failed to conclude that the PHYSTATUS bit of the PCS_STATUS register used in PCIe and USB3 falls as the PHY gets ready. Similar to the prior bug with UFS the code will generally get past the check before the transition and thereby "succeed". Correct the name of the register used PCIe and USB3 PHYs, replace mask_pcs_ready with a constant expression depending on the type of the PHY and check for the appropriate ready state.

stable backports, from contents found in xilinx-4.9

I searched through https://github.com/Xilinx/linux-xlnx/tree/xlnx_rebase_v4.9 for commits that got backported from mainline, and categorized them to see if we want them in an LTS kernel.
