Subject: [patch 1/2] fix call to alloc_bootmem after bootmem has been freed
Date: Wed, 15 Nov 2006 19:32:38 +0100 [thread overview]
Message-ID: <20061115193238.4d23900c@localhost> (raw)
In-Reply-To: <20061115193049.3457b44c@localhost>
In some cases it might happen, that alloc_bootmem is beeing called
after bootmem pages have been freed. This is, because the condition
SYSTEM_BOOTING is still true after bootmem has been freed.
