ARM: convert printk(KERN_* to pr_* 2014-11-21T15:24:50+00:00 Russell King rmk+kernel@arm.linux.org.uk 2014-10-28T11:26:42+00:00 4ed89f2228061422ce5f62545fd0b6f6648bd2cc Convert many (but not all) printk(KERN_* to pr_* to simplify the code. We take the opportunity to join some printk lines together so we don't split the message across several lines, and we also add a few levels to some messages which were previously missing them.

ARM: 8148/1: flush TLS and thumbee register state during exec 2014-09-16T15:09:32+00:00 Nathan Lynch nathan_lynch@mentor.com 2014-09-11T01:49:08+00:00 fbfb872f5f417cea48760c535e0ff027c88b507a The TPIDRURO and TPIDRURW registers need to be flushed during exec; otherwise TLS information is potentially leaked. TPIDRURO in particular needs careful treatment. Since flush_thread basically needs the same code used to set the TLS in arm_syscall, pull that into a common set_tls helper in tls.h and use it in both places. Similarly, TEEHBR needs to be cleared during exec as well. Clearing its save slot in thread_info isn't right as there is no guarantee that a thread switch will occur before the new program runs. Just setting the register directly is sufficient.
