Administrivia: remove old list address

2024-05-02 Thread Stephen Rothwell
Hi all, Many years ago, linuxppc-dev was moved from ozlabs.org to lists.ozlabs.org. These days most of the mail sent to linuxppc-dev @ozlabs.org is spam (causing added burden to the list owner i.e. me), so I intend to drop that name. Initially, it will bounce with a message pointing to the new

[PATCH] power: Remove arch specific module bug stuff

From: "Dr. David Alan Gilbert" The last function to reference module_bug_list went in 2008's commit b9754568ef17 ("powerpc: Remove dead module_find_bug code") but I don't think that was called since 2006's commit 73c9ceab40b1 ("[POWERPC] Generic BUG for powerpc") Now that the list has gone,

[PATCH] [RFC] scsi: Convert from tasklet to BH workqueue

2024-05-02 Thread Allen Pais
The only generic interface to execute asynchronously in the BH context is tasklet; however, it's marked deprecated and has some design flaws. To replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items are

[PATCH v4 1/2] powerpc64/bpf: fix tail calls for PCREL addressing

2024-05-02 Thread Hari Bathini
With PCREL addressing, there is no kernel TOC. So, it is not setup in prologue when PCREL addressing is used. But the number of instructions to skip on a tail call was not adjusted accordingly. That resulted in not so obvious failures while using tailcalls. 'tailcalls' selftest crashed the system

[PATCH v4 2/2] powerpc/bpf: enable kfunc call

2024-05-02 Thread Hari Bathini
Currently, bpf jit code on powerpc assumes all the bpf functions and helpers to be part of core kernel text. This is false for kfunc case, as function addresses may not be part of core kernel text area. So, add support for addresses that are not within core kernel text area too, to enable kfunc
