Subject: [patch 01/41] cpu_alloc: Increase percpu area size to 128k
Date: Thu, 29 May 2008 20:56:21 -0700 [thread overview]
Message-ID: <20080530040010.806208523@sgi.com> (raw)
In-Reply-To: 20080530035620.587204923@sgi.com
[-- Attachment #1: ia64_increase_percpu_size --]
[-- Type: text/plain, Size: 910 bytes --]
The per cpu allocator requires more per cpu space and we are already near
the limit on IA64. Increase the maximum size of the IA64 per cpu area from
64K to 128K.
