The SPU code doesn't properly invalidate SPUs SLBs when necessary, for example when changing a segment size from the hugetlbfs code. In addition, it saves and restores the SLB content on context switches which makes it harder to properly handle those invalidations. This patch removes the saving & restoring for now, something more efficient might be found later on. It also adds a spu_flush_all_slbs(mm) that can be used by the core mm code to flush the SLBs of all SPEs that are running a given mm at the time of the flush. In order to do that, it adds a spinlock to the list of all SPEs and move some bits & pieces from spufs to spu_base.c Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

* Kexec adds some code to arch/ia64/kernel/smp.c which needs ia64_mca_pal_base, so the kexec patch (actually the kdump patch) declares this per-cpu variable in include/asm-ia64/kexec.h. * ia64_mca_pal_base is defined in arch/ia64/kernel/mca.c, so it seems to me that it would make a lot more sense to declare it in include/asm-ia64/mca.h.

Jack Steiner noticed that duplicate TLB DTC entries do not cause a linux panic. See discussion: http://www.gelato.unsw.edu.au/archives/linux-ia64/0307/6108.html The current TLB recovery code is recovering from the duplicate itr.d dropins, masking the underlying problem. This change modifies the MCA recovery code to look for the TLB check signature of the duplicate TLB entry and panic in that case.

IA64 and ARM-OABI are currently using their own version of epoll compat_ code. An architecture needs epoll_event translation if alignof(u64) in 32 bit mode is different from alignof(u64) in 64 bit mode. If an architecture needs epoll_event translation, it must define struct compat_epoll_event in asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use compat_sys_epoll_ctl and compat_sys_epoll_wait. All 64 bit architecture should use compat_sys_epoll_pwait.

The security hooks to check permissions to remove an xfrm_policy were actually done after the policy was removed. Since the unlinking and deletion are done in xfrm_policy_by* functions this moves the hooks inside those 2 functions. There we have all the information needed to do the security check and it can be done before the deletion. Since auditing requires the result of that security check err has to be passed back and forth from the xfrm_policy_by* functions. This patch also fixes a bug where a deletion that failed the security check could cause improper accounting on the xfrm_policy (xfrm_get_policy didn't have a put on the exit path for the hold taken by xfrm_policy_by*) It also fixes the return code when no policy is found in xfrm_add_pol_expire. In old code (at least back in the 2.6.18 days) err wasn't used before the return when no policy is found and so the initialization would cause err to be ENOENT. But since err has since been used above when we don't get a policy back from the xfrm_policy_by* function we would always return 0 instead of the intended ENOENT. Also fixed some white space damage in the same area.

This reverts commit 39d61db0. The commit was buggy in multiple ways: - the conversion to ilog2() was incorrect to begin with - it tested the wrong #defines, so on all architectures but FRV you'd never see the bug except for constant arguments. - the new "get_order()" macro used its arguments multiple times, and didn't even parenthesize them properly - despite the comments, it was not true that you could use it for constant initializers, since not all architectures even use the generic page.h header file. All of the problems are individually fixable, but it all boils down to: better just revert it, and re-do it from scratch.

The address where the ELF core header is stored is passed to the secondary kernel as a kernel command line option. The memory area for this header is also marked as a separate EFI memory descriptor on ia64. The separate EFI memory descriptor is at the moment of the type EFI_UNUSABLE_MEMORY. With such a type the secondary kernel skips over the entire memory granule (config option, 16M or 64M) when detecting memory. If we are lucky we will just lose some memory, but if we happen to have data in the same granule (such as an initramfs image), then this data will never get mapped and the kernel bombs out when trying to access it. So this is an attempt to fix this by changing the EFI memory descriptor type into EFI_LOADER_DATA. This type is the same type used for the kernel data and for initramfs. In the secondary kernel we then handle the ELF core header data the same way as we handle the initramfs image. This patch contains the kernel changes to make this happen. Pretty straightforward, we reserve the area in reserve_memory(). The address for the area comes from the kernel command line and the size comes from the specialized EFI parsing function vmcore_find_descriptor_size().

When the last thread of nfsd exits, it shuts down all related sockets. It currently uses svc_close_socket to do this, but that only is immediately effective if the socket is not SK_BUSY. If the socket is busy - i.e. if a request has arrived that has not yet been processes - svc_close_socket is not effective and the shutdown process spins. So create a new svc_force_close_socket which removes the SK_BUSY flag is set and then calls svc_close_socket. Also change some open-codes loops in svc_destroy to use list_for_each_entry_safe.

Prior to commit 95492e46 ([PATCH] x86: rewrite SMP TSC sync code), the headers in asm-i386 did not really require anything in include/asm-x86_64. This means that distributions such as fedora did not include asm-x86_64 in kernel-devel headers for i386. Ingo's commit changed that, and broke things. This is easy enough to hack around in package builds by just including asm-x86_64 on i386, but that's kind of annoying. If anything, x86_64 should depend upon i386, not the other way around. This patch changes it so that asm-x86_64/tsc.h includes asm-i386/tsc.h, rather than vice-versa.

We were using the platform_device.id field to identify which ethernet port is used for mv643xx_eth device. This is not generally correct. It will be incorrect, for example, if a hardware platform uses a single port but not the first port. Here, we add an explicit port_number field to struct mv643xx_eth_platform_data.

In active-backup mode, the current bonding code duplicates IGMP traffic to all slaves, so that switches are up to date in case of a failover from an active to a backup interface. If bonding then fails back to the original active interface, it is likely that the "active slave" switch's IGMP forwarding for the port will be out of date until some event occurs to refresh the switch (e.g., a membership query). This patch alters the behavior of bonding to no longer flood IGMP to all ports, and to issue IGMP JOINs to the newly active port at the time of a failover. This insures that switches are kept up to date for all cases. "GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally reported this problem, and included a patch. His original patch was modified by Jay Vosburgh to additionally remove the existing IGMP flood behavior, use RCU, streamline code paths, fix trailing white space, and adjust for style.
