2010-02-08sh: Don't continue unwinding across interruptsMatt Fleming
Unfortunately, due to poor DWARF info in current toolchains, unwinding through interrutps cannot be done reliably. The problem is that the DWARF info for function epilogues is wrong. Take this standard epilogue sequence, 80003cc4: e3 6f mov r14,r15 80003cc6: 26 4f lds.l @r15+,pr 80003cc8: f6 6e mov.l @r15+,r14 <---- interrupt here 80003cca: f6 6b mov.l @r15+,r11 80003ccc: f6 6a mov.l @r15+,r10 80003cce: f6 69 mov.l @r15+,r9 80003cd0: 0b 00 rts If we take an interrupt at the highlighted point, the DWARF info will bogusly claim that the return address can be found at some offset from the frame pointer, even though the frame pointer was just restored. The worst part is if the unwinder finds a text address at the bogus stack address - unwinding will continue, for a bit, until it finally comes across an unexpected address on the stack and blows up. The only solution is to stop unwinding once we've calculated the function that was executing when the interrupt occurred. This PC can be easily calculated from pt_regs->pc.

2010-02-08sh: Setup frame pointer in handle_exception pathMatt Fleming
In order to allow the DWARF unwinder to unwind through exceptions we need to setup the frame pointer register (r14). Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-08sh: Correct the offset of the return address in ret_from_exceptionMatt Fleming
The address that ret_from_exception and ret_from_irq will return to is found in the stack slot for SPC, not PR. This error was causing the DWARF unwinder to pick up the wrong return address on the stack and then unwind using the unwind tables for the wrong function. While I'm here I might as well add CFI annotations for the other registers since they could be useful when unwinding.

2010-02-08sh: fix Transfer Size calculation in both DMA driversGuennadi Liakhovetski
Both the original arch/sh/drivers/dma/dma-sh.c and the new SH dmaengine drivers do not take into account bits 3:2 of the Transfer Size field in the CHCR register, besides, bit-field defines set bit 2, but the mask only passes bits 1:0 through. TS_16BLK and TS_32BLK macros are bogus too. This patch fixes all these issues for sh7722 and sh7724, other CPUs stay unchanged and might need to be fixed too.

2010-02-08sh: prepare the DMA driver for slave functionalityGuennadi Liakhovetski
Slave DMA functionality uses scatter-gather arrays for data transfers, whereas memcpy just uses a single data buffer. This patch converts the current memcpy implementation in shdma.c to use scatter-gather, making it just a special case with one SG-element. This allows us to isolate descriptor list manipulations and locking into one function, thus reducing error chances.

2010-02-07Fix race in tty_fasync() properlyLinus Torvalds
This reverts commit 703625118069 ("tty: fix race in tty_fasync") and commit b04da8bfdfbb ("fnctl: f_modown should call write_lock_irqsave/ restore") that tried to fix up some of the fallout but was incomplete. It turns out that we really cannot hold 'tty->ctrl_lock' over calling __f_setown, because not only did that cause problems with interrupt disables (which the second commit fixed), it also causes a potential ABBA deadlock due to lock ordering. Thanks to Tetsuo Handa for following up on the issue, and running lockdep to show the problem. It goes roughly like this: - f_getown gets filp->f_owner.lock for reading without interrupts disabled, so an interrupt that happens while that lock is held can cause a lockdep chain from f_owner.lock -> sighand->siglock. - at the same time, the tty->ctrl_lock -> f_owner.lock chain that commit 703625118069 introduced, together with the pre-existing sighand->siglock -> tty->ctrl_lock chain means that we have a lock dependency the other way too. So instead of extending tty->ctrl_lock over the whole __f_setown() call, we now just take a reference to the 'pid' structure while holding the lock, and then release it after having done the __f_setown. That still guarantees that 'struct pid' won't go away from under us, which is all we really ever needed.

Because we may have aliases, like __GI___strcoll_l in /lib64/libc-2.10.2.so that appears in objdump as: $ objdump --start-address=0x0000003715a86420 \ --stop-address=0x0000003715a872dc -dS /lib64/libc-2.10.2.so 0000003715a86420 <__strcoll_l>: 3715a86420: 55 push %rbp 3715a86421: 48 89 e5 mov %rsp,%rbp 3715a86424: 41 57 push %r15 [root@doppio linux-2.6-tip]# So look for the address exactly at the start of the line instead so that annotation can work for in these cases.

2010-02-07perf top: Fix annotate for userspaceKirill Smelkov
First, for programs and prelinked libraries, annotate code was fooled by objdump output IPs (src->eip in the code) being wrongly converted to absolute IPs. In such case there were no conversion needed, but in src->eip = strtoull(src->line, NULL, 16); src->eip = map->unmap_ip(map, src->eip); // = eip + map->start - map->pgoff we were reading absolute address from objdump (e.g. 8048604) and then almost doubling it, because eip & map->start are approximately close for small programs. Needless to say, that later, in record_precise_ip() there was no matching with real runtime IPs. And second, like with `perf annotate` the problem with non-prelinked *.so was that we were doing rip -> objdump address conversion wrong. Also, because unlike `perf annotate`, `perf top` code does annotation based on absolute IPs for performance reasons(*), new helper for mapping objdump addresse to IP is introduced. (*) we get samples info in absolute IPs, and since we do lots of hit-testing on absolute IPs at runtime in record_precise_ip(), it's better to convert objdump addresses to IPs once and do no conversion at runtime. I also had to fix how objdump output is parsed (with hardcoded 8/16 characters format, which was inappropriate for ET_DYN dsos with small addresses like '4ac') Also note, that not all objdump output lines has associtated IPs, e.g. look at source lines here: 000004ac <my_strlen>: extern "C" int my_strlen(const char *s) 4ac: 55 push %ebp 4ad: 89 e5 mov %esp,%ebp 4af: 83 ec 10 sub $0x10,%esp { int len = 0; 4b2: c7 45 fc 00 00 00 00 movl $0x0,-0x4(%ebp) 4b9: eb 08 jmp 4c3 <my_strlen+0x17> while (*s) { ++len; 4bb: 83 45 fc 01 addl $0x1,-0x4(%ebp) ++s; 4bf: 83 45 08 01 addl $0x1,0x8(%ebp) So we mark them with eip=0, and ignore such lines in annotate lookup code.

2010-02-07ima: initialize ima before inodes can be allocatedEric Paris
ima wants to create an inode information struct (iint) when inodes are allocated. This means that at least the part of ima which does this allocation (the allocation is filled with information later) should before any inodes are created. To accomplish this we split the ima initialization routine placing the kmem cache allocator inside a security_initcall() function. Since this makes use of radix trees we also need to make sure that is initialized before security_initcall().

2010-02-07fix ima breakageMimi Zohar
The "Untangling ima mess, part 2 with counters" patch messed up the counters. Based on conversations with Al Viro, this patch streamlines ima_path_check() by removing the counter maintaince. The counters are now updated independently, from measuring the file, in __dentry_open() and alloc_file() by calling ima_counts_get(). ima_path_check() is called from nfsd and do_filp_open(). It also did not measure all files that should have been measured. Reason: ima_path_check() got bogus value passed as mask.

2010-02-07freeze_bdev: don't deactivate successfully frozen MS_RDONLY sbJun'ichi Nomura
Thanks Thomas and Christoph for testing and review. I removed 'smp_wmb()' before up_write from the previous patch, since up_write() should have necessary ordering constraints. (I.e. the change of s_frozen is visible to others after up_write) I'm quite sure the change is harmless but if you are uncomfortable with Tested-by/Reviewed-by on the modified patch, please remove them. If MS_RDONLY, freeze_bdev should just up_write(s_umount) instead of deactivate_locked_super(). Also, keep sb->s_frozen consistent so that remount can check the frozen state.

2010-02-05hwmon: (w83781d) Request I/O ports individually for probingJean Delvare
Different motherboards have different PNP declarations for W83781D/W83782D chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have a W83781D or W83782D chip, the useful port range will be requested again, as a single block. I did not see a board which needs this yet, but I know of one for lm78 driver and I'd like to keep the logic of these two drivers in sync.

2010-02-05hwmon: (lm78) Request I/O ports individually for probingJean Delvare
Different motherboards have different PNP declarations for LM78/LM79 chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have an LM78 or LM79 chip, the useful port range will be requested again, as a single block. This fixes the driver on the Olivetti M3000 DT 540, at least.

2010-02-05hwmon: (adt7462) Wrong ADT7462_VOLT_COUNTRay Copeland
The #define ADT7462_VOLT_COUNT is wrong, it should be 13 not 12. All the for loops that use this as a limit count are of the typical form, "for (n = 0; n < ADT7462_VOLT_COUNT; n++)", so to loop through all voltages w/o missing the last one it is necessary for the count to be one greater than it is. (Specifically, you will miss the +1.5V 3GPIO input with count = 12 vs. 13.) Signed-off-by: Ray Copeland <ray.copeland@aprius.com> Acked-by: "Darrick J.

2010-02-05xfs: fix xfs to work with Virtually Indexed architecturesJames Bottomley
xfs_buf.c includes what is essentially a hand rolled version of blk_rq_map_kern(). In order to work properly with the vmalloc buffers that xfs uses, this hand rolled routine must also implement the flushing API for vmap/vmalloc areas.

2010-02-05arm: add mm API for DMA to vmalloc/vmap areasJames Bottomley
ARM cannot prevent cache movein, so this patch implements both the flush and invalidate pieces of the API. Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2010-02-05parisc: add mm API for DMA to vmalloc/vmap areasJames Bottomley
We already have an API to flush a kernel page along an alias address, so use it. The TLB purge prevents the CPU from doing speculative moveins on the flushed address, so we don't need to implement and invalidate.
