[lkp-robot] dcda20b368: unixbench.score -2.3% regression
by kernel test robot
Greeting,
FYI, we noticed a -2.3% regression of unixbench.score due to commit:
commit: dcda20b3685f14d4d29d31592fe9898943fce1bb ("Fill in ELF image holes with PROT_NONE to prevent mapping to the hole")
url: https://github.com/0day-ci/linux/commits/blackzert-gmail-com/Fill-in-ELF-...
in testcase: unixbench
on test machine: 12 threads Intel(R) Atom(R) CPU 3958 @ 2.00GHz with 64G memory
with following parameters:
runtime: 300s
nr_task: 1
test: execl
cpufreq_governor: performance
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:

ACPI / CPPC: Make cppc acpi driver aware of pcc subspace ids
Based on ACPI 6.2 Section 8.4.7.1.9 If the PCC register space is used,
all PCC registers, for all processors in the same performance
domain (as defined by _PSD), must be defined to be in the same subspace.
Based on Section 14.1 of ACPI specification, it is possible to have a
maximum of 256 PCC subspace ids. Add support of multiple PCC subspace id
instead of using a single global pcc_data structure.
While at that fix the time_delta check in send_pcc_cmd() so that last_mpar_reset
and mpar_count is initialized properly.

776c6d679d ("lib: test_rhashtable: fix for large entry counts"): BUG: KASAN: stack-out-of-bounds in jhash
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/0day-ci/linux/commits/Phil-Sutter/lib-test_rhashtable-...
commit 776c6d679dc8b68c81e210eb07c7418dcd9f47f6
Author: Phil Sutter <phil(a)nwl.cc>
AuthorDate: Fri Jul 21 16:51:31 2017 +0200
Commit: 0day robot <fengguang.wu(a)intel.com>
CommitDate: Sun Jul 23 11:46:57 2017 +0800
lib: test_rhashtable: fix for large entry counts
During concurrent access testing, threadfunc() concatenated thread ID
and object index to create a unique key like so:
| tdata->objs[i].value = (tdata->id << 16) | i;
This breaks if a user passes an entries parameter of 64k or higher,
since 'i' might use more than 16 bits then. Effectively, this will lead
to duplicate keys in the table.
Fix the problem by introducing a struct holding object and thread ID and
using that as key instead of a single integer type field.
Fixes: f4a3e90ba5739 ("rhashtable-test: extend to test concurrency")
Reported by: Manuel Messner <mm(a)skelett.io>

06dc75ab06 ("net: Revert "net: add function to allocate .."): BUG: unable to handle kernel paging request at d79df002
by kernel test robot
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 06dc75ab06943fcc126a951a0680980ad5cb75c6
Author: Florian Westphal <fw(a)strlen.de>
AuthorDate: Mon Jul 17 18:56:54 2017 +0200

CommitDate: Mon Jul 17 10:34:21 2017 -0700
net: Revert "net: add function to allocate sk_buff head without data area"
It was added for netlink mmap tx, there are no callers in the tree.
The commit also added a check for skb->head != NULL in kfree_skb path,
remove that too -- all skbs ought to have skb->head set.

Unless you are running in a virtual machine, this could cause serious problems such as overwriting CMOS
or similar which could potentially make this machine unbootable without a firmware reset.
ctrl-c now unless you really know what you are doing.

ASoC: Intel: board: Add Geminilake platform support
Geminilake also features rt298 codec, so use the same machine driver
as Broxton. Geminilake uses SSP2 instead of SSP5.
