2008-12-17USB: skip Set-Interface(0) if already in altsetting 0Alan Stern
When a driver unbinds from an interface, usbcore always sends a Set-Interface request to reinstall altsetting 0. Unforunately, quite a few devices have buggy firmware that crashes when it receives this request. To avoid such problems, this patch (as1180) arranges to send the Set-Interface request only when the interface is not already in altsetting 0.

2008-12-16powerpc/cell/axon-msi: Fix MSI after kexecArnd Bergmann
Commit d015fe995 'powerpc/cell/axon-msi: Retry on missing interrupt' has turned a rare failure to kexec on QS22 into a reproducible error, which we have now analysed. The problem is that after a kexec, the MSIC hardware still points into the middle of the old ring buffer. We set up the ring buffer during reboot, but not the offset into it. On older kernels, this would cause a storm of thousands of spurious interrupts after a kexec, which would most of the time get dropped silently. With the new code, we time out on each interrupt, waiting for it to become valid. If more interrupts come in that we time out on, this goes on indefinitely, which eventually leads to a hard crash. The solution in this commit is to read the current offset from the MSIC when reinitializing it. This now works correctly, as expected.

2008-12-16powerpc: Fix bootmem reservation on uninitialized nodeDave Hansen
careful_allocation() was calling into the bootmem allocator for nodes which had not been fully initialized and caused a previous bug: http://patchwork.ozlabs.org/patch/10528/ So, I merged a few broken out loops in do_init_bootmem() to fix it. That changed the code ordering. I think this bug is triggered by having reserved areas for a node which are spanned by another node's contents. In the mark_reserved_regions_for_nid() code, we attempt to reserve the area for a node before we have allocated the NODE_DATA() for that nid. We do this since I reordered that loop. I suck. This is causing crashes at bootup on some systems, as reported by Jon Tollefson. This may only present on some systems that have 16GB pages reserved. But, it can probably happen on any system that is trying to reserve large swaths of memory that happen to span other nodes' contents. This commit ensures that we do not touch bootmem for any node which has not been initialized, and also removes a compile warning about an unused variable.

2008-12-16powerpc: Check for valid hugepage size in hugetlb_get_unmapped_areaBrian King
It looks like most of the hugetlb code is doing the correct thing if hugepages are not supported, but the mmap code is not. If we get into the mmap code when hugepages are not supported, such as in an LPAR which is running Active Memory Sharing, we can oops the kernel. This fixes the oops being seen in this path. oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=1024 NUMA pSeries Modules linked in: nfs(N) lockd(N) nfs_acl(N) sunrpc(N) ipv6(N) fuse(N) loop(N) dm_mod(N) sg(N) ibmveth(N) sd_mod(N) crc_t10dif(N) ibmvscsic(N) scsi_transport_srp(N) scsi_tgt(N) scsi_mod(N) Supported: No NIP: c000000000038d60 LR: c00000000003945c CTR: c0000000000393f0 REGS: c000000077e7b830 TRAP: 0300 Tainted: G (2.6.27.5-bz50170-2-ppc64) MSR: 8000000000009032 <EE,ME,IR,DR> CR: 44000448 XER: 20000001 DAR: c000002000af90a8, DSISR: 0000000040000000 TASK = c00000007c1b8600[4019] 'hugemmap01' THREAD: c000000077e78000 CPU: 6 GPR00: 0000001fffffffe0 c000000077e7bab0 c0000000009a4e78 0000000000000000 GPR04: 0000000000010000 0000000000000001 00000000ffffffff 0000000000000001 GPR08: 0000000000000000 c000000000af90c8 0000000000000001 0000000000000000 GPR12: 000000000000003f c000000000a73880 0000000000000000 0000000000000000 GPR16: 0000000000000000 0000000000000000 0000000000000000 0000000000010000 GPR20: 0000000000000000 0000000000000003 0000000000010000 0000000000000001 GPR24: 0000000000000003 0000000000000000 0000000000000001 ffffffffffffffb5 GPR28: c000000077ca2e80 0000000000000000 c00000000092af78 0000000000010000 NIP [c000000000038d60] .slice_get_unmapped_area+0x6c/0x4e0 LR [c00000000003945c] .hugetlb_get_unmapped_area+0x6c/0x80 Call Trace: [c000000077e7bbc0] [c00000000003945c] .hugetlb_get_unmapped_area+0x6c/0x80 [c000000077e7bc30] [c000000000107e30] .get_unmapped_area+0x64/0xd8 [c000000077e7bcb0] [c00000000010b140] .do_mmap_pgoff+0x140/0x420 [c000000077e7bd80] [c00000000000bf5c] .sys_mmap+0xc4/0x140 [c000000077e7be30] [c0000000000086b4] syscall_exit+0x0/0x40 Instruction dump: fac1ffb0 fae1ffb8 fb01ffc0 fb21ffc8 fb41ffd0 fb61ffd8 fb81ffe0 fbc1fff0 fbe1fff8 f821fef1 f8c10158 f8e10160 <7d49002e> f9010168 e92d01b0 eb4902b0 Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-12-15cgroups: fix a race between rmdir and remountPaul Menage
When a cgroup is removed, it's unlinked from its parent's children list, but not actually freed until the last dentry on it is released (at which point cgrp->root->number_of_cgroups is decremented). Currently rebind_subsystems checks for the top cgroup's child list being empty in order to rebind subsystems into or out of a hierarchy - this can result in the set of subsystems bound to a hierarchy being removed-but-not-freed cgroup. The simplest fix for this is to forbid remounts that change the set of subsystems on a hierarchy that has removed-but-not-freed cgroups. This bug can be reproduced via: mkdir /mnt/cg mount -t cgroup -o ns,freezer cgroup /mnt/cg mkdir /mnt/cg/foo sleep 1h < /mnt/cg/foo & rmdir /mnt/cg/foo mount -t cgroup -o remount,ns,devices,freezer cgroup /mnt/cg kill $! Though the above will cause oops in -mm only but not mainline, but the bug can cause memory leak in mainline (and even oops) Signed-off-by: Paul Menage <menage@google.com> Reviewed-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-12-15ACPI toshiba: only register rfkill if bt is enabledFrederik Deweerdt
Part of the rfkill initialization was done whenever BT was on or not. The following patch checks for BT presence before registering the rfkill to the input layer. Some minor cleanups (> 80 char lines) were also added in the process.
