Shutemov" Date: Fri, 8 May 2015 13:25:26 +0300 Subject: [PATCH] x86/kconfig: Fix the CONFIG_NR_CPUS description Since: b53b5eda8194 ("x86/cpu: Increase max CPU count to 8192") ... the maximum supported NR_CPUS for CPUMASK_OFFSTACK case is 8192. Let's adjust the description to reflect the change. Signed-off-by: Kirill A.
