Subject: linux-next: build failure after merge of the char-misc tree
Date: Fri, 7 Aug 2015 16:32:14 +1000 [thread overview]
Message-ID: <20150807163214.25c10a5f@canb.auug.org.au> (raw)
Hi all,
After merging the char-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/hv/hv.c: In function 'read_hv_clock_tsc':
drivers/hv/hv.c:154:4: error: implicit declaration of function 'rdtscll' [-Werror=implicit-function-declaration]
rdtscll(cur_tsc);
^
Caused by commit
ca9357bd26c2 ("Drivers: hv: vmbus: Implement a clocksource based on the TSC page")
interacting with commits
87be28aaf145 ("x86/asm/tsc: Replace rdtscll() with native_read_tsc()")
4ea1636b04db ("x86/asm/tsc: Rename native_read_tsc() to rdtsc()")
from the tip tree.
Please consider maintaining API's for a release cycle when changing them.
I have applied the following merge fix patch:
