2011-05-29[S390] mm: fix storage key handlingHeiko Carstens
page_get_storage_key() and page_set_storage_key() expect a page address and not its page frame number. This got inconsistent with 2d42552d "[S390] merge page_test_dirty and page_clear_dirty". Result is that we read/write storage keys from random pages and do not have a working dirty bit tracking at all. E.g. SetPageUpdate() doesn't clear the dirty bit of requested pages, which for example ext4 doesn't like very much and panics after a while. Unable to handle kernel paging request at virtual user address (null) Oops: 0004 [#1] PREEMPT SMP DEBUG_PAGEALLOC Modules linked in: CPU: 1 Not tainted 2.6.39-07551-g139f37f-dirty #152 Process flush-94:0 (pid: 1576, task: 000000003eb34538, ksp: 000000003c287b70) Krnl PSW : 0704c00180000000 0000000000316b12 (jbd2_journal_file_inode+0x10e/0x138) R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:3 CC:0 PM:0 EA:3 Krnl GPRS: 0000000000000000 0000000000000000 0000000000000000 0700000000000000 0000000000316a62 000000003eb34cd0 0000000000000025 000000003c287b88 0000000000000001 000000003c287a70 000000003f1ec678 000000003f1ec000 0000000000000000 000000003e66ec00 0000000000316a62 000000003c287988 Krnl Code: 0000000000316b04: f0a0000407f4 srp 4(11,%r0),2036,0 0000000000316b0a: b9020022 ltgr %r2,%r2 0000000000316b0e: a7740015 brc 7,316b38 >0000000000316b12: e3d0c0000024 stg %r13,0(%r12) 0000000000316b18: 4120c010 la %r2,16(%r12) 0000000000316b1c: 4130d060 la %r3,96(%r13) 0000000000316b20: e340d0600004 lg %r4,96(%r13) 0000000000316b26: c0e50002b567 brasl %r14,36d5f4 Call Trace: ([<0000000000316a62>] jbd2_journal_file_inode+0x5e/0x138) [<00000000002da13c>] mpage_da_map_and_submit+0x2e8/0x42c [<00000000002daac2>] ext4_da_writepages+0x2da/0x504 [<00000000002597e8>] writeback_single_inode+0xf8/0x268 [<0000000000259f06>] writeback_sb_inodes+0xd2/0x18c [<000000000025a700>] writeback_inodes_wb+0x80/0x168 [<000000000025aa92>] wb_writeback+0x2aa/0x324 [<000000000025abde>] wb_do_writeback+0xd2/0x274 [<000000000025ae3a>] bdi_writeback_thread+0xba/0x1c4 [<00000000001737be>] kthread+0xa6/0xb0 [<000000000056c1da>] kernel_thread_starter+0x6/0xc [<000000000056c1d4>] kernel_thread_starter+0x0/0xc INFO: lockdep is turned off.

2011-05-28Blackfin: debug-mmrs: include RSI_PID[4567] MMRsMike Frysinger
The documentation is a little iffy as to whether these are actual MMRs, but reading them on the hardware works, and the previous version of this logic (the SDH) had PID[4567]. So add it for RSI too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-05-28Blackfin: bf52x/bf54x: fix up usb MMR definesMike Frysinger
The bf52x/bf54x have the incorrect addresses for USB_EP_NI7_RXINTERVAL and USB_EP_NI7_TXCOUNT, so adjust those. Further, the bf54x header puts the USB defines in the wrong place, so shuffle them back to the right grouping. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-05-28Blackfin: debug-mmrs: fix typos with gptimers/mdma/ppiMike Frysinger
This code was mostly developed against a BF54x, so some BF537-specific issues were missed. The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse of the EPPI block). The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the sim does not catch misreads here so that'll need to get fixed. The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct to figure that out rather than hardcoding it locally. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* setns: ns: Wire up the setns system call Done as a merge to make it easier to fix up conflicts in arm due to addition of sendmmsg system call
2011-05-28ns: Wire up the setns system callEric W. Biederman
32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com> v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. >  arch/blackfin/include/asm/unistd.h     |    3 ++- >  arch/blackfin/mach-common/entry.S      |    1 + Acked-by: Mike Frysinger <vapier@gentoo.org> Oh - ia64 wiring looks good.

2011-05-26cgroup: remove the ns_cgroupDaniel Lezcano
The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. This patch removes the ns_cgroup as suggested in the following thread: https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html The 'cgroup_clone' function is removed because it is no longer used. This is a userspace-visible change. Commit 45531757b45c ("cgroup: notify ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a printk warning users that the feature is planned for removal. Since that time we have heard from XXX users who were affected by this. Signed-off-by: Daniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: Serge E. Hallyn <serge.hallyn@canonical.com> Cc: Eric W.

2011-05-26m32r: convert cpumask apiKOSAKI Motohiro
We plan to remove cpus_xx() old cpumask APIs later. Also, we plan to change mm_cpu_mask() implementation, allocate only nr_cpu_ids, thus *mm_cpu_mask() is dangerous operation. Then, this patch convert them.
