Date: Tue, 19 Aug 2014 15:22:43 +0800 From: "Wang, Yalin" <Yalin.Wang@...ymobile.com> To: "'linux-arm-kernel@...ts.infradead.org'" <linux-arm-kernel@...ts.infradead.org>, 'Will Deacon' <will.deacon@....com>, "'linux-kernel@...r.kernel.org'" <linux-kernel@...r.kernel.org> Subject: CONFIG_ENABLE_VMALLOC_SAVING problem Hi I found when I enable CONFIG_ENABLE_VMALLOC_SAVING on ARM arch, Vmalloc still only use VMALLOC_START -- VMALLOC_END virtual address, It don't use the memory hole address, Only function call get_vm_area_caller like ioremap can use These memory hole address . Why not change vmalloc also use this address? Another problem is that when I cat /proc/meminfo , The VmallocTotal item show doesn't include memory hole address, It only show VMALLOC_START -- VMALLOC_END , I think it is not correct here , should add memory hole as vmalloc when CONFIG_ENABLE_VMALLOC_SAVING is enabled , isn't it ?
