Hi Oza,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on v4.16] [cannot apply to pci/next linus/master next-20180410] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url: https://github.com/0day-ci/linux/commits/Oza-Pawandeep/Address-error-and-recovery-for-AER-and-DPC/20180410-045644 config: x86_64-randconfig-s4-04101607 (attached as .config) compiler: gcc-7 (Debian 7.3.0-1) 7.3.0 reproduce: # save the attached .config to linux build tree make ARCH=x86_64
Note: the linux-review/Oza-Pawandeep/Address-error-and-recovery-for-AER-and-DPC/20180410-045644 HEAD db413d3e52b272ef8e6f03ff125e65468abd31e6 builds fine. It only hurts bisectibility.
All errors (new ones prefixed by >>):
