192ffafb71 ("idr: Convert to XArray"): BUG: KASAN: use-after-free in xas_set_tag
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.infradead.org/users/willy/linux-dax.git xarray-2017-12-11
commit 192ffafb71abe8cd3ac76d24c1f4c00ce192108c

idr: Convert to XArray
The IDR distinguishes between unallocated entries (read as NULL) and
entries where the user has chosen to store NULL. The radix tree was
modified to consider NULL entries which had tag 0 _clear_ as being
allocated, but it added a lot of complexity.
Instead, the XArray has a 'zero entry', which the normal API will treat
as NULL, but is distinct from NULL when using the advanced API. The IDR
code converts between NULL and zero entries.
The idr_for_each_entry_ul() iterator becomes an alias for xa_for_each(),
so we drop the idr_get_next_ul() function as it has no users.
The exported IDR API was a weird mix of GPL-only and general symbols;
I converted them all to GPL as there was no way to use the IDR API
without being GPL.

[lkp-robot] [x86/entry/64] 11a1251e3a: hackbench.throughput -12.1% regression
by kernel test robot
Greeting,
We noticed a -12.1% regression of hackbench.throughput due to commit:
commit: 11a1251e3a3cc9532f358c889deea63169bd2c65 ("x86/entry/64: Make cpu_entry_area.tss read-only")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: hackbench
on test machine: 256 threads Phi with 96G memory
with following parameters:
nr_threads: 100%
mode: threads
ipc: pipe
cpufreq_governor: performance
test-description: Hackbench is both a benchmark and a stress test for the Linux kernel scheduler.
test-url: https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sc...
Details are as below:

To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
