From e2c75fcae4d72b229830ae7e7438d544bb71bf89 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 30 May 2017 15:20:37 -0700 Subject: module: Fix pr_fmt() bug for header use of printk This commit removes the pr_fmt() macro, replacing it with mod_err() and mod_debug() macros to avoid errors when using printk() from header files.

McKenney" Date: Thu, 29 Jun 2017 15:53:02 -0700 Subject: arch: Remove spin_unlock_wait() arch-specific definitions There is no agreed-upon definition of spin_unlock_wait()'s semantics, and it appears that all callers could do just as well with a lock/unlock pair. This commit therefore removes the underlying arch-specific arch_spin_unlock_wait() for all architectures providing them. Signed-off-by: Paul E.
