tracing: Fix tp_printk option related with tp_printk_stop_on_boot

2022-02-23T10:56:41+00:00

[ Upstream commit 3203ce39ac0b2a57a84382ec184c7d4a0bede175 ] The kernel parameter "tp_printk_stop_on_boot" starts with "tp_printk" which is the same as another kernel parameter "tp_printk". If "tp_printk" setup is called before the "tp_printk_stop_on_boot", it will override the latter and keep it from being set. This is similar to other kernel parameter issues, such as: Commit 745a600cf1a6 ("um: console: Ignore console= option") or init/do_mounts.c:45 (setup function of "ro" kernel param) Fix it by checking for a "_" right after the "tp_printk" and if that exists do not process the parameter.

ata: libata-core: Disable TRIM on M88V29

2022-02-23T10:56:41+00:00

[ Upstream commit c8ea23d5fa59f28302d4e3370c75d9c308e64410 ] This device is a CF card, or possibly an SSD in CF form factor. It supports NCQ and high speed DMA. While it also advertises TRIM support, I/O errors are reported when the discard mount option fstrim is used. TRIM also fails when disabling NCQ and not just as an NCQ command. TRIM must be disabled for this device. Signed-off-by: Zoltán Böszörményi Signed-off-by: Damien Le Moal Signed-off-by: Sasha Levin

commit 9d2231c5d74e13b2a0546fee6737ee4446017903 upstream. The functions copy_page_to_iter_pipe() and push_pipe() can both allocate a new pipe_buffer, but the "flags" member initializer is missing.

i2c: brcmstb: fix support for DSL and CM variants

commit 834cea3a252ed4847db076a769ad9efe06afe2d5 upstream. DSL and CM (Cable Modem) support 8 B max transfer size and have a custom DT binding for that reason. This driver was checking for a wrong "compatible" however which resulted in an incorrect setup.

EDAC: Fix calculation of returned address and next offset in edac_align_ptr()

2022-02-23T10:56:41+00:00

commit f8efca92ae509c25e0a4bd5d0a86decea4f0c41e upstream. Do alignment logic properly and use the "ptr" local variable for calculating the remainder of the alignment. This became an issue because struct edac_mc_layer has a size that is not zero modulo eight, and the next offset that was prepared for the private data was unaligned, causing an alignment exception. The patch in Fixes: which broke this actually wanted to "what we actually care about is the alignment of the actual pointer that's about to be returned." But it didn't check that alignment. Use the correct variable "ptr" for that.
