2018-08-13parisc: Fix and improve kernel stack unwindingHelge Deller1-6/+0
This patchset fixes and improves stack unwinding a lot: 1. Show backward stack traces with up to 30 callsites 2. Add callinfo to ENTRY_CFI() such that every assembler function will get an entry in the unwind table 3. Use constants instead of numbers in call_on_stack() 4. Do not depend on CONFIG_KALLSYMS to generate backtraces. 5. Speed up backtrace generation Make sure you have this patch to GNU as installed: https://sourceware.org/ml/binutils/2018-07/msg00474.html Without this patch, unwind info in the kernel is often wrong for various functions.

This trivial patch fixes the following section warnings on PARISC: > WARNING: vmlinux.o (.text.1): unexpected section name. >The (.[number]+) following section name are ld generated and not expected. > Did you forget to use "ax"/"aw" in a .S file? > Note that for example <linux/init.h> contains > section definitions for use in .S files.

2005-10-22[PARISC] Properly specify section alignment for real2.SGrant Grundler1-1/+1
.align applies to the current section - ie section directives come first. Thanks to Joel Soete for catching this. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2005-10-22[PARISC] Make sure use of RFI conforms to PA 2.0 and 1.1 arch docsGrant Grundler1-12/+6
2.6.12-rc4-pa3 : first pass at making sure use of RFI conforms to PA 2.0 arch pages F-4 and F-5, PA 1.1 Arch page 3-19 and 3-20. The discussion revolves around all the rules for clearing PSW Q-bit. The hard part is meeting all the rules for "relied upon translation". .align directive is used to guarantee the critical sequence ends more than 8 instructions (32 bytes) from the end of page.

2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+304
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
