This replaceable mainboard only has a VGA-out, yet it claims to also have a connected LVDS header. Addresses https://bugs.freedesktop.org/show_bug.cgi?id=63860 [jani.nikula@intel.com: use DMI_EXACT_MATCH for board name.] Signed-off-by:

dmi_match() considers a substring match to be a successful match. This is not always sufficient to distinguish between DMI data for different systems. Add support for exact string matching using strcmp() in addition to the substring matching using strstr(). The specific use case in the i915 driver is to allow us to use an exact match for D510MO, without also incorrectly matching D510MOV: { .ident = "Intel D510MO", .matches = { DMI_MATCH(DMI_BOARD_VENDOR, "Intel"), DMI_EXACT_MATCH(DMI_BOARD_NAME, "D510MO"), }, } Signed-off-by: -

Add functionality to serialize the output from dump_stack() to avoid mangling of the output when dump_stack is called simultaneously from multiple cpus. [akpm@linux-foundation.org: fix comment indenting, avoid inclusion of <asm/> files - use <linux/> where possiblem fix uniprocessor build (__dump_stack undefined), remove unneeded ifdef around smp.h inclusion] Signed-off-by:

Calling kthread_run with a single name parameter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents. Signed-off-by:

For the workqueue creation interfaces that do not expect format strings, make sure they cannot accidently be parsed that way. Additionally, clean up calls made with a single parameter that would be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents. Signed-off-by:

Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register(). Signed-off-by:

Fix various weird constructions of strncpy(dst, src, strlen(src)). Length limits should be about the space available in the destination, not repurposed as a method to either always include or always exclude a trailing NULL byte. Either the NULL should always be copied (using strlcpy), or it should not be copied (using something like memcpy). Readable code should not depend on the weird behavior of strncpy when it hits the length limit. Better to avoid the anti-pattern entirely.

Sparse generates a false positive when you pass a __user or __iomem pointer to the IS_ERR() functions. drivers/rtc/rtc-ds1286.c:344:36: sparse: incorrect type in argument 1 (different address spaces) drivers/rtc/rtc-ds1286.c:344:36: expected void const *ptr drivers/rtc/rtc-ds1286.c:344:36: got unsigned int [noderef] [usertype] <asn:2>*rtcregs We can silence these by adding a __force here and upgrading to Sparse v0.4.5-rc1 or later. This change has no effect when using current Sparse releases. Signed-off-by:

'cmdline' is a NUL terminated string, when its length < 4, memcmp() will cause memory access out of boundary. So use strncmp() instead of memcmp(). Signed-off-by:

mem_cgroup_iter() is too hard to follow. Factor out the lockless reclaim iterator loading and updating so it's easier to follow the big picture. Also document the iterator invalidation mechanism a bit more extensively. Signed-off-by:

Here we pass flags with only VM_ALLOC bit set, it is unnecessary to call clear_vm_unlist to clear VM_UNLIST bit. So use setup_vmalloc_vm instead of insert_vmalloc_vm. Signed-off-by:
-
Zhang Yanfei authored
Now for insert_vmalloc_vm, it only calls the two functions: - setup_vmalloc_vm: fill vm_struct and vmap_area instances - clear_vm_unlist: clear VM_UNLIST bit in vm_struct->flags So in __get_vm_area_node(), if VM_UNLIST bit unset in flags, that is the else branch here, we don't need to clear VM_UNLIST bit for vm->flags since this bit is obviously not set. That is to say, we could only call setup_vmalloc_vm instead of insert_vmalloc_vm here. And then we could even remove the if test here. Signed-off-by:

Instead of leaving a hidden trap for the next person who comes along and wants to add something to mem_section, add a big fat warning about it needing to be a power-of-2, and insert a BUILD_BUG_ON() in sparse_init() to catch mistakes. Right now non-power-of-2 mem_sections cause a number of WARNs at boot (which don't clearly point to the size of mem_section as an issue), but the system limps on (temporarily, at least). This is based upon Dave Hansen's earlier RFC where he ran into the same issue: "sparsemem: fix boot when SECTIONS_PER_ROOT is not power-of-2" http://lkml.indiana.edu/hypermail/linux/kernel/1205.2/03077.htmlSigned-off-by:
