2012-09-27um: Preinclude include/linux/kern_levels.hGeert Uytterhoeven
The userspace part of UML uses the asm-offsets.h generator mechanism to create definitions for UM_KERN_<LEVEL> that match the in-kernel KERN_<LEVEL> constant definitions. As of commit 04d2c8c83d0e3ac5f78aeede51babb3236200112 ("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern"), KERN_<LEVEL> is no longer expanded to the literal '"<LEVEL>"', but to '"\001" "LEVEL"', i.e. it contains two parts. However, the combo of DEFINE_STR() in arch/x86/um/shared/sysdep/kernel-offsets.h and sed-y in Kbuild doesn't support string literals consisting of multiple parts. Hence for all UM_KERN_<LEVEL> definitions, only the SOH character is retained in the actual definition, while the remainder ends up in the comment. E.g. in include/generated/asm-offsets.h we get #define UM_KERN_INFO "\001" /* "6" KERN_INFO */ instead of #define UM_KERN_INFO "\001" "6" /* KERN_INFO */ This causes spurious '^A' output in some kernel messages: Calibrating delay loop... 4640.76 BogoMIPS (lpj=23203840) pid_max: default: 32768 minimum: 301 Mount-cache hash table entries: 256 ^AChecking that host ptys support output SIGIO...Yes ^AChecking that host ptys support SIGIO on close...No, enabling workaround ^AUsing 2.6 host AIO NET: Registered protocol family 16 bio: create slab <bio-0> at 0 Switching to clocksource itimer To fix this: - Move the mapping from UM_KERN_<LEVEL> to KERN_<LEVEL> from arch/um/include/shared/common-offsets.h to arch/um/include/shared/user.h, which is preincluded for all userspace parts, - Preinclude include/linux/kern_levels.h for all userspace parts, to obtain the in-kernel KERN_<LEVEL> constant definitions. This doesn't violate the kernel/userspace separation, as include/linux/kern_levels.h is self-contained and doesn't expose any other kernel internals. - Remove the now unused STR() and DEFINE_STR() macros.

Pull more networking fixes from David Miller: 1) Eric Dumazet discovered and fixed what turned out to be a family of bugs. These functions were using pskb_may_pull() which might need to reallocate the linear SKB data buffer, but the callers were not expecting this possibility. The callers have cached pointers to the packet header areas, and would need to reload them if we were to continue using pskb_may_pull(). So they could end up reading garbage. It's easier to just change these RAW4/RAW6/MIP6 routines to use skb_header_pointer() instead of pskb_may_pull(), which won't modify the linear SKB data area. 2) Dave Jone's syscall spammer caught a case where a non-TCP socket can call down into the TCP keepalive code. The case basically involves creating a raw socket with sk_protocol == IPPROTO_TCP, then calling setsockopt(sock_fd, SO_KEEPALIVE, ...) Fixed by Eric Dumazet. 3) Bluetooth devices do not get configured properly while being powered on, resulting in always using legacy pairing instead of SSP. Fix from Andrzej Kaczmarek. 4) Bluetooth cancels delayed work erroneously, put stricter checks in place. From Andrei Emeltchenko. 5) Fix deadlock between cfg80211_mutex and reg_regdb_search_mutex in cfg80211, from Luis R. Rodriguez. 6) Fix interrupt double release in iwlwifi, from Emmanuel Grumbach. 7) Missing module license in bcm87xx driver, from Peter Huewe. 8) Team driver can lose port changed events when adding devices to a team, fix from Jiri Pirko. 9) Fix endless loop when trying ot unregister PPPOE device in zombie state, from Xiaodong Xu. 10) batman-adv layer needs to set MAC address of software device earlier, otherwise we call tt_local_add with it uninitialized. 11) Fix handling of KSZ8021 PHYs, it's matched currently by KS8051 but that doesn't program the device properly.

We end up in the situation where the initial domain gets too much information and gets confused and crashes - the fix is to restrict the domain to get the information - and we do it by just disabling NUMA on the PV guest (the hypervisor is still able to do its proper NUMA allocations of guests). It is OK to disable the PV guest from accessing NUMA data as right now we do not inject any NUMA node information to the PV guests. When we do get to that point, then this patch will have to be reverted." * Disable PV NUMA support as we do not do anything with it (yet) and it can cause bootup crashes on certain AMD machines. * tag 'stable/for-linus-3.6-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/boot: Disable NUMA for PV guests.

An ABI numbering change was made in the hypervisor for Tilera's 4.1 MDE release (just shipped).

2012-09-24c6x: use asm-generic/barrier.hMark Salter
A recent patch in the linux-next tree caused a build failure on C6X because C6X didn't define a read_barrier_depends() macro. C6X does not support SMP and the architecture doesn't provide any special memory ordering instructions, so it makes sense to just use the generic barrier.h rather than patching the existing c6x specific header. Signed-off-by: Mark Salter <msalter@redhat.com>
2012-09-24xen/boot: Disable NUMA for PV guests.Konrad Rzeszutek Wilk
The hypervisor is in charge of allocating the proper "NUMA" memory and dealing with the CPU scheduler to keep them bound to the proper NUMA node. The PV guests (and PVHVM) have no inkling of where they run and do not need to know that right now. In the future we will need to inject NUMA configuration data (if a guest spans two or more NUMA nodes) so that the kernel can make the right choices. But those patches are not yet present. In the meantime, disable the NUMA capability in the PV guest, which also fixes a bootup issue. Andre says: "we see Dom0 crashes due to the kernel detecting the NUMA topology not by ACPI, but directly from the northbridge (CONFIG_AMD_NUMA). This will detect the actual NUMA config of the physical machine, but will crash about the mismatch with Dom0's virtual memory. Variation of the theme: Dom0 sees what it's not supposed to see. This happens with the said config option enabled and on a machine where this scanning is still enabled (K8 and Fam10h, not Bulldozer class) We have this dump then: NUMA: Warning: node ids are out of bound, from=-1 to=-1 distance=10 Scanning NUMA topology in Northbridge 24 Number of physical nodes 4 Node 0 MemBase 0000000000000000 Limit 0000000040000000 Node 1 MemBase 0000000040000000 Limit 0000000138000000 Node 2 MemBase 0000000138000000 Limit 00000001f8000000 Node 3 MemBase 00000001f8000000 Limit 0000000238000000 Initmem setup node 0 0000000000000000-0000000040000000 NODE_DATA [000000003ffd9000 - 000000003fffffff] Initmem setup node 1 0000000040000000-0000000138000000 NODE_DATA [0000000137fd9000 - 0000000137ffffff] Initmem setup node 2 0000000138000000-00000001f8000000 NODE_DATA [00000001f095e000 - 00000001f0984fff] Initmem setup node 3 00000001f8000000-0000000238000000 Cannot find 159744 bytes in node 3 BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffff81d220e6>] __alloc_bootmem_node+0x43/0x96 Pid: 0, comm: swapper Not tainted 3.3.6 #1 AMD Dinar/Dinar RIP: e030:[<ffffffff81d220e6>] [<ffffffff81d220e6>] __alloc_bootmem_node+0x43/0x96 .. snip..

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Pull Xen bug-fixes from Konrad Rzeszutek Wilk: - Fix M2P batching re-using the incorrect structure field. In v3.5 we added batching for M2P override (Machine Frame Number -> Physical Frame Number), but the original MFN was saved in an incorrect structure - and we would oops/restore when restoring with the old MFN. - Disable BIOS SMP MP table search. A bootup issue that we had ignored until we found that on DL380 G6 it was needed. * tag 'stable/for-linus-3.6-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/boot: Disable BIOS SMP MP table search. xen/m2p: do not reuse kmap_op->dev_bus_addr
2012-09-21ARM: reserve syscall 378 for kcmpRussell King
kcmp has appeared on x86, but has not been noticed because checksyscalls.sh is broken at the moment. Reserve ARM syscall 378 for this should we ever need it, and add an __IGNORE entry for this unimplemented syscall. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-09-21x86/kbuild: archscripts depends on scripts_basicJeff Mahoney
While building the SUSE kernel packages, which build the scripts, make clean, and then build everything, we have been running into spurious build failures. We tracked them down to a simple dependency issue: $ make mrproper CLEAN arch/x86/tools CLEAN scripts/basic $ cp patches/config/x86_64/desktop .config $ make archscripts HOSTCC arch/x86/tools/relocs /bin/sh: scripts/basic/fixdep: No such file or directory make[3]: *** [arch/x86/tools/relocs] Error 1 make[2]: *** [archscripts] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 This was introduced by commit 6520fe55 (x86, realmode: 16-bit real-mode code support for relocs), which added the archscripts dependency to archprepare. This patch adds the scripts_basic dependency to the x86 archscripts. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
