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.

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.

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..

Likewise its calendar manipulation commands interpret or set the RTC registers unconditionally as binary, never actually checking what the value of the DM bit is, under the (correct) assumption that it has been previously set, to indicate the binary mode. A change to Linux a while ago however introduced a platform-specific tweak that clears that bit and therefore forces the data mode to BCD. This causes clock corruption and misinterpretation that has to be fixed up by user-mode tools in system startup scripts as the initial clock is often incorrect according to the BCD interpretation forced. This change removes the hack; a comment included refers to alarm code, but even if it was broken at one point by requiring the BCD mode, it should have been trivially corrected and even if not, given how rarely the alarm feature is used, that was not really a reasonable justification to break the system clock that is indeed used by virtually everything. And either way the alarm code has been since fixed anyway. Signed-off-by: Maciej W.

A small fix to the ARM decompressor to ensure that the page tables are properly interpreted by the CPU, and reserve syscall 378 for kcmp (the checksyscalls.sh script is unfortunately currently broken so arch maintainers aren't getting notified of new syscalls...)

But the managed clk functions are merely wrappers around clk_get and clk_put and do not depend on any specifics of the generic lookup functions and there are still quite a few custom implementations of the clk API. So make the managed functions available whenever the clk API is implemented. The patch also removes the custom implementation of devm_clk_get for the coldfire platform.

To fix the warning, let's convert common clk users over to clk notifiers in place of CPUfreq notifiers. This works out nicely for Cortex-A9 MPcore designs that scale all CPUs at the same frequency. Platforms that have not been converted to the common clk framework and support CPUfreq will rely on the old mechanism. Once these platforms are converted over fully then we can remove the CPUfreq-specific bits for good.

Also there is no UOPS_DISPATCHED.THREAD on IVB, so do not populate the PERF_COUNT_HW_STALLED_CYCLES_BACKEND mapping.

This is also needed to distinguish between future kernels what might support a feature. Cc: <stable@vger.kernel.org> v3.5..

This is because the internal irqs now start at an offset of NR_IRQS_LEGACY. The patch fixed this up, but missed the i.MX25 timer which used a hardcoded value instead of a define. This patch introduces a define for the timer irq and uses it.
