[PATCH v2] ARM: vexpress_defconfig: Enable voltage regulators

by Christoffer Dall

Enable voltage regulators by default for versatile express. This should work on all verstatile express platforms and not enabling it prevents a defconfig'ed kernel from using the SD card controller on the qemu emulated platform, which is unfortunate for first-time casual users.

[PATCH 00/25] tty: serial: drop uart_port->lock before calling

by Viresh Kumar

The -rt patch triggers a lockdep warning for serial drivers if tty_flip_buffer_push() is called with uart_port->lock locked. This never shows up on UP kernels. Release the port lock before calling tty_flip_buffer_push() and reacquire it after the call. Similar stuff was already done for few other drivers in the past, like: commit 2389b272168ceec056ca1d8a870a97fa9c26e11a Author: Thomas Gleixner <tglx(a)linutronix.de> Date: Tue May 29 21:53:50 2007 +0100 [ARM] 4417/1: Serial: Fix AMBA drivers locking This is neither tested nor compiled.

Since vexpress_defconfig is known broken (https://bugs.launchpad.net/linaro-ci/+bug/1212893), what's the next step to move forward?
