Input: input_event - fix the CONFIG_SPARC64 mixup

2019-01-31T07:14:42Z

commit 141e5dcaa7356077028b4cd48ec351a38c70e5e5 upstream. Arnd Bergmann pointed out that CONFIG_* cannot be used in a uapi header. Override with an equivalent conditional.

Input: input_event - provide override for sparc64

2019-01-31T07:14:37Z

commit 2e746942ebacf1565caa72cf980745e5ce297c48 upstream. The usec part of the timeval is defined as __kernel_suseconds_t tv_usec; /* microseconds */ Arnd noticed that sparc64 is the only architecture that defines __kernel_suseconds_t as int rather than long. This breaks the current y2038 fix for kernel as we only access and define the timeval struct for non-kernel use cases. But, this was hidden by an another typo in the use of __KERNEL__ qualifier. Fix the typo, and provide an override for sparc64.

x86/speculation: Add prctl() control for indirect branch speculation
