| manpage-debug-packages.patch | Mention the -debug package split In Debian systems, the special debug libraries (with extra assertions, checks and logging, not suitable for production) are placed in a separate binary package with the "-debug" suffix. These are only meant to be installed when specific troubleshooting is required. Instructions for this troubleshooting are included in the library manpages, and we add a note explaining that the respective -debug package should be installed. |

| 0001-pmem2-arm64-fix-data-loss-on-ARMv8.2-improper-flushi.patch | [PATCH] pmem2: arm64: fix data loss on ARMv8.2+ (improper flushing) ARMv8.2 separates flush-for-coherency from flush-for-persistency as two to us, and it is up to the processor to know where the Point of Persistency happens to be. The documentation is very clear, and this PIRL talk dispels all doubt: https://www.youtube.com/watch?v=8QAuN8CL5Zg On the other hand, I found no clear answer whether DC CVAC might be enough on some pre-8.2 hardware. There's no other option though (CVAC is the heaviest flush available). This question is probably moot as pre-8.2 CPUs, while ubiquitous in dev boards, are gone in datacenter gear. |

| 0001-common-fix-missing-sfence-in-non-temporal-memcpy.patch | [PATCH] common: fix missing sfence in non-temporal memcpy The implementation of hardware fencing for non-temporal memcpy variants is done using a function pointer. Some of those pointers are called "barrier" which unfortunately overlaps with a function-like macro that's used for compiler barriers. This meant that a compiler barrier was being used instead of a hardware store barrier. This patch changes the compiler barrier to a static inline function called "compiler_barrier" to avoid name conflicts. Fixes #5292 |
