Commit ed7b1889 removed page.h from include/asm-generic/Kbuild so that it shouldn't get exported. However, it was redundantly listed in asm-mn10300/Kbuild and asm-x86/Kbuild too.

Introduce new LSM interfaces to allow an FS to deal with their own mount options. This includes a new string parsing function exported from the LSM that an FS can use to get a security data blob and a new security data blob. This is particularly useful for an FS which uses binary mount data, like NFS, which does not pass strings into the vfs to be handled by the loaded LSM. Also fix a BUG() in both SELinux and SMACK when dealing with binary mount data. If the binary mount data is less than one page the copy_page() in security_sb_copy_data() can cause an illegal page fault and boom. Remove all NFSisms from the SELinux code since they were broken by past NFS changes.

Replace free_hot_cold_page's VM_BUG_ON(page_get_page_cgroup(page)) by a "Bad page state" and clear: most users don't have CONFIG_DEBUG_VM on, and if it were set here, it'd likely cause corruption when the page is reused. Don't use page_assign_page_cgroup to clear it: that should be private to memcontrol.c, and always called with the lock taken; and memmap_init_zone doesn't need it either - like page->mapping and other pointers throughout the kernel, Linux assumes pointers in zeroed structures are NULL pointers.

The definitions of struct pci_device_id arrays should generally follow the same pattern across the entire kernel. This macro defines this array as const and puts it into the __devinitconst section. There are currently many definitions scattered about the kernel that omit the __devinitdata modifier despite the documentation stating that it should always be there. These definitions really also should have been const, which wasn't possible before but has become so with the addition of the __devinitconst attribute. Furthermore, there are definitions that use "const" and __devinitdata, which is explicitly wrong but the compiler doesn't catch section mismatches if there's only one such one case in the module (which is often the case). Adding the __devinitconst modifier where there was nothing before buys us memory. Adding the const modifier gives the compiler a chance to do its thing. Changing __devinitdata to __devinitconst where it was wrong actually fixes some compiler errors in older (mid-release) kernels that were patched over by "removing" the section attribute altogether (which wastes memory). This macro makes it pretty difficult to get this definition wrong in the future... Signed-off-by: NJonas Bonn <jonas@southpole.se> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

If all of the entropy is in the local and foreign addresses, but xor'ing together would cancel out that entropy, the current hash performs poorly. Suggested by Cosmin Ratiu: Basically, the situation is as follows: There is a client machine and a server machine. Both create 15000 virtual interfaces, open up a socket for each pair of interfaces and do SIP traffic. By profiling I noticed that there is a lot of time spent walking the established hash chains with this particular setup. The addresses were distributed like this: client interfaces were 198.18.0.1/16 with increments of 1 and server interfaces were 198.18.128.1/16 with increments of 1. As I said, there were 15000 interfaces. Source and destination ports were 5060 for each connection. So in this case, ports don't matter for hashing purposes, and the bits from the address pairs used cancel each other, meaning there are no differences in the whole lot of pairs, so they all end up in the same hash chain.

Fix the problem that the following error message is sometimes displayed at irq migration when vector domain is enabled. "Unexpected interrupt vector %d on CPU %d is not mapped to any IRQ!" The cause of this problem is an interrupt is sent to the previous target CPU after cleaning up vector to irq mapping table. To clean up vector to irq map on the previous target CPU safty, change the irq migration in multiple vector domain as follows. The original idea is from x86 interrupt management code. - Delay vector to irq table cleanup until the interrupts are sent to new target CPUs. By this, it is ensured that target CPU is completely changed on the interrupt controller side. - Even after the interrupts are sent to new target CPUs, there can be pended interrupts remaining on the previous target CPU. So we need to delay clearning up vector to irq table until the pended interrupt is handled. For this, send IPI to the previous target CPU with lower priority vector and clean up vector to irq table in its handler. This patch affects only to irq migration code with multiple vector domain is enabled. Signed-off-by: NKenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: NTony Luck <tony.luck@intel.com>
