[PATCH v2 1/6] ext4: sysfs: print ext4_super_block fields as little-endian

by Arnd Bergmann

While working on extended rand for last_error/first_error timestamps, I noticed that the endianess is wrong, we access the little-endian fields in struct ext4_super_block as native-endian when we print them. This adds a special case in ext4_attr_show() and ext4_attr_store() to byteswap the superblock fields if needed. In older kernels, this code was part of super.c, it got moved to sysfs.c in linux-4.4.

[PATCH] xhci: Fix perceived dead host due to runtime suspend race with event handler

by Kai-Heng Feng

From: Mathias Nyman <mathias.nyman(a)linux.intel.com> commit 229bc19fd7aca4f37964af06e3583c1c8f36b5d6 upstream. Don't rely on event interrupt (EINT) bit alone to detect pending port change in resume. If no change event is detected the host may be suspended again, oterwise roothubs are resumed. There is a lag in xHC setting EINT. If we don't notice the pending change in resume, and the controller is runtime suspeded again, it causes the event handler to assume host is dead as it will fail to read xHC registers once PCI puts the controller to D3 state.

If the device fails to come back online after a resume cycle, reads from vram will return all 1s which will cause a segfault. Based on a patch from Thomas Martitz <kugel(a)rockbox.org>. This avoids the segfault, but we still need to sort out why the GPU does not come back online after a resume.
