Sasha, your kernel has CONFIG_DEBUG_PAGEALLOC enabled, right? __free_pages_memory() hands the memory area to the buddy page allocator which marks the pages not-present in the page table if CONFIG_DEBUG_PAGEALLOC is set by calling kernel_map_pages(). reserved array doesn't tend to be too big and ends up surrounded by other reserved areas to avoid being returned to page allocator but on your setup it ends up being doubled towards the end of the boot process and gets unmapped triggering page fault on the following attempt to access the table.

No, it is not early. at that time memblock usage is done. Also I tested one system with huge memory, duplicated the problem on KVM that Sasha met. my patch fixes the problem. please check attached patch. Also I add another patch to double check if there is any reference with reserved.region. so far there is no reference found. Thanks Yinghai [-- Attachment #2: fix_free_memblock_reserve_v4_5.patch --] [-- Type: application/octet-stream, Size: 6770 bytes --] Subject: [PATCH] memblock: free allocated memblock_reserved_regions later In memblock_free_reserved_regions, will call memblock_free(), but memblock_free() would double reserved.regions too, so we could free old range for reserved.regions. Also tj said there is another bug could be related to this too. | I don't think we're saving any noticeable | amount by doing this "free - give it to page allocator - reserve | again" dancing. We should just allocate regions aligned to page | boundaries and free them later when memblock is no longer in use. So try to allocate that in PAGE_SIZE alignment and free that later. -v5: Use new_alloc_size, and old_alloc_size to simplify it according to tj.

During converting bootmem to use early_res stage, I still kept the numa handling. like one node by one node. So need to put the reserved.regions back. Later found we could do that for all node at the same time. For memory.regions, a little different, at that time I want to kill e820 all like e820_all_mapped_ram. Yes, we should get back region that is allocated for doubled memory.regions. but did not trigger that doubling yet.

What am I missing? 64bit mem_init(), after absent_page_in_range(), will not need memblock anymore. --- absent_page_in_range will refer for_each_mem_pfn_range. so after that could clear that for memory.regions too.

Yeah, it's okay but just not optimal. I was wondering what changed. My setup is pretty similar and in case you're intersted, here are some tricks I've been using. Thunderbird * In the Composition & Addressing tab of account setting, clear "Compose messages in HTML format". * Open Config Editor under Preferences -> Advanced -> General. * set mailnews.wraplength to 9999 * set mailnews.send_plaintext_flowed to false * Install External Editor add-on and configure it to your favorite editor. http://globs.org/articles.php?pg=2&lng=en Ctrl-E launches the external editor. The only caveat is that there seems to be a race condition and if the machine is under heavy load the extension occassinally loses the edited text, so it usually is a good idea to save a copy in a separate file before exiting the external editor. It never happens on my desktop but happens on my laptop once in a blue moon. Alternatively, you can use mutt for patch sending / processing. With caches turned on (set header_cache, set message_cachedir), it's actually pretty useable w/ gmail. -- tejun ^ permalink raw reply [flat|nested] 71+ messages in thread

Yeah, it's okay but just not optimal. I was wondering what changed. My setup is pretty similar and in case you're intersted, here are some tricks I've been using. Thunderbird * In the Composition & Addressing tab of account setting, clear "Compose messages in HTML format". * Open Config Editor under Preferences -> Advanced -> General. * set mailnews.wraplength to 9999 * set mailnews.send_plaintext_flowed to false * Install External Editor add-on and configure it to your favorite editor. http://globs.org/articles.php?pg=2&lng=en Ctrl-E launches the external editor. The only caveat is that there seems to be a race condition and if the machine is under heavy load the extension occassinally loses the edited text, so it usually is a good idea to save a copy in a separate file before exiting the external editor. It never happens on my desktop but happens on my laptop once in a blue moon. Alternatively, you can use mutt for patch sending / processing. With caches turned on (set header_cache, set message_cachedir), it's actually pretty useable w/ gmail. -- tejun -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
