Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git locking/core
commit d0541b0fa64b36665d6261079974a26943c75009
Author: Byungchul Park

locking/lockdep: Make CONFIG_LOCKDEP_CROSSRELEASE part of
CONFIG_PROVE_LOCKING
Crossrelease support added the CONFIG_LOCKDEP_CROSSRELEASE and
CONFIG_LOCKDEP_COMPLETE
options. It makes little sense to enable them when PROVE_LOCKING is
disabled.
Make them non-interative options and part of PROVE_LOCKING to simplify the
UI.

9c2fb296dd ("Makefile: move stackprotector availability out of .."): BUG: kernel hang in early-boot stage, last printk:
Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master commit 9c2fb296dde16a1bb81277be7b32cec881fe1153 Author: Kees Cook AuthorDate: Mon Oct 16 20:01:58 2017 +0100 Commit: Mark Brown CommitDate: Mon Oct 16 20:01:58 2017 +0100 Makefile: move stackprotector availability out of Kconfig Various portions of the kernel, especially per-architecture pieces, need to know if the compiler is building it with the stack protector. This was done in the arch/Kconfig with 'select', but this doesn't allow a way to do auto-detected compiler support. In preparation for creating an on-if-available default, move the logic for the definition of CONFIG_CC_STACKPROTECTOR into the Makefile.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit e181ae0c5db9544de9c53239eb22bc012ce75033
Author: Pavel Tatashin
AuthorDate: Sat Jul 14 09:15:07 2018 -0400

mm: zero unavailable pages before memmap init
We must zero struct pages for memory that is not backed by physical
memory, or kernel does not have access to.
Recently, there was a change which zeroed all memmap for all holes in
e820. Unfortunately, it introduced a bug that is discussed here:
https://www.spinics.net/lists/linux-mm/msg156764.html
Linus, also saw this bug on his machine, and confirmed that reverting
commit 124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into
memblock.reserved") fixes the issue.
The problem is that we incorrectly zero some struct pages after they
were setup.
The fix is to zero unavailable struct pages prior to initializing of
struct pages.
A more detailed fix should come later that would avoid double zeroing
cases: one in __init_single_page(), the other one in
zero_resv_unavail().
Fixes: 124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into
memblock.reserved")

[lkp-robot] ee410f15b1 BUG: kernel hang in boot stage
Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit ee410f15b1418f2f4428e79980674c979081bcb7 Author: Thierry Escande AuthorDate: Thu Jun 14 15:28:15 2018 -0700 Commit: Linus Torvalds CommitDate: Fri Jun 15 07:55:25 2018 +0900 lib/test_printf.c: call wait_for_random_bytes() before plain %p tests If the test_printf module is loaded before the crng is initialized, the plain 'p' tests will fail because the printed address will not be hashed and the buffer will contain '(ptrval)' instead. This patch adds a call to wait_for_random_bytes() before plain 'p' tests to make sure the crng is initialized.
