Hello everyone, Here's the situation: Back in 2012, we cloned a MIPS repo, which was itself a clone of a 3.4.2 kernel with ~40 MIPS-specific patches applied. Then the devs started pushing patches; and once in a while, the maintainer would "sync" with the mainline kernel. I don't know what tool he used to sync, but he discarded the original patches doing so, and git blame now shows him as the author of every mainline change since the clone. Now that we are moving to a more recent kernel, I'm trying to "fix" this situation, i.e. I'd like kernel code to have proper attribution in git blame, while keeping intact the information for "internal" commits. While I'm at it, I want to minimize history by ignoring patches that are now irrelevant: 1) we don't support MIPS anymore, I want to ignore any internal change we made in the arch/mips directory 2) for some reason, there was a large amount of create/delete churn in arch/arm/configs; so I want to ignore our changes, and I'll commit an acceptable config when the process is complete. 3) ignore some internal platform-specific patches (NB: All these "ignores" are for internal patches, not mainline patches) Sooo, using git log and grep, I came up with a list of ~300 patches I'd like to apply on top of the latest 3.14 kernel. For testing purposes, I used git format-patch on the oldest of my 300 patches. I then made a shiny new clone of linux-stable.git, and tried using git am to apply that patch to the tip of linux-stable, expecting having to solve a few dozens conflicts, and move on (hoping to automate it at some point). But 'git am' just gave up. Small sample of errors: error: patch failed: drivers/block/Kconfig:411 error: drivers/block/Kconfig: patch does not apply error: drivers/tty/serial/8250/8250.c: does not exist in index error: patch failed: drivers/tty/serial/8250/8250_early.c:121 error: drivers/tty/serial/8250/8250_early.c: patch does not apply error: patch failed: drivers/video/Kconfig:101 error: drivers/video/Kconfig: patch does not apply ... Patch failed at 0001 Commit for supporting Sigma Designs' SoCs. The copy of the patch that failed is found in: .git/rebase-apply/patch When you have resolved this problem, run "git am --continue". If you prefer to skip this patch, run "git am --skip" instead. To restore the original branch and stop patching, run "git am --abort". How do I "resolve this problem". I suppose I am doing this the wrong way. What is the correct way to do it? (I'm using git 2.3) Should I use git am -3 in the original repo?
