Subject: [PATCH 3.2 41/87] x86/boot: Double BOOT_HEAP_SIZE to 64KB
Date: Mon, 08 Feb 2016 23:53:51 +0000 [thread overview]
Message-ID: <lsq.1454975631.899407608@decadent.org.uk> (raw)
In-Reply-To: <lsq.1454975630.125133756@decadent.org.uk>
3.2.77-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "H.J. Lu" <hjl.tools@gmail.com>
commit 8c31902cffc4d716450be549c66a67a8a3dd479c upstream.
When decompressing kernel image during x86 bootup, malloc memory
for ELF program headers may run out of heap space, which leads
to system halt. This patch doubles BOOT_HEAP_SIZE to 64KB.
Tested with 32-bit kernel which failed to boot without this patch.
