2013-01-21ftrace: Be first to run code modification on modulesSteven Rostedt
If some other kernel subsystem has a module notifier, and adds a kprobe to a ftrace mcount point (now that kprobes work on ftrace points), when the ftrace notifier runs it will fail and disable ftrace, as well as kprobes that are attached to ftrace points. Here's the error: WARNING: at kernel/trace/ftrace.c:1618 ftrace_bug+0x239/0x280() Hardware name: Bochs Modules linked in: fat(+) stap_56d28a51b3fe546293ca0700b10bcb29__8059(F) nfsv4 auth_rpcgss nfs dns_resolver fscache xt_nat iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack lockd sunrpc ppdev parport_pc parport microcode virtio_net i2c_piix4 drm_kms_helper ttm drm i2c_core [last unloaded: bid_shared] Pid: 8068, comm: modprobe Tainted: GF 3.7.0-0.rc8.git0.1.fc19.x86_64 #1 Call Trace: [<ffffffff8105e70f>] warn_slowpath_common+0x7f/0xc0 [<ffffffff81134106>] ? __probe_kernel_read+0x46/0x70 [<ffffffffa0180000>] ? 0xffffffffa017ffff [<ffffffffa0180000>] ? 0xffffffffa017ffff [<ffffffff8105e76a>] warn_slowpath_null+0x1a/0x20 [<ffffffff810fd189>] ftrace_bug+0x239/0x280 [<ffffffff810fd626>] ftrace_process_locs+0x376/0x520 [<ffffffff810fefb7>] ftrace_module_notify+0x47/0x50 [<ffffffff8163912d>] notifier_call_chain+0x4d/0x70 [<ffffffff810882f8>] __blocking_notifier_call_chain+0x58/0x80 [<ffffffff81088336>] blocking_notifier_call_chain+0x16/0x20 [<ffffffff810c2a23>] sys_init_module+0x73/0x220 [<ffffffff8163d719>] system_call_fastpath+0x16/0x1b ---[ end trace 9ef46351e53bbf80 ]--- ftrace failed to modify [<ffffffffa0180000>] init_once+0x0/0x20 [fat] actual: cc:bb:d2:4b:e1 A kprobe was added to the init_once() function in the fat module on load. But this happened before ftrace could have touched the code. As ftrace didn't run yet, the kprobe system had no idea it was a ftrace point and simply added a breakpoint to the code (0xcc in the cc:bb:d2:4b:e1). Then when ftrace went to modify the location from a call to mcount/fentry into a nop, it didn't see a call op, but instead it saw the breakpoint op and not knowing what to do with it, ftrace shut itself down. The solution is to simply give the ftrace module notifier the max priority. This should have been done regardless, as the core code ftrace modification also happens very early on in boot up. This makes the module modification closer to core modification.

2013-01-21i2c: mxs: Fix misuse init_completionMarek Vasut
The init_completion() call does reinit not only the variable carrying the flag that the completion finished, but also initialized the waitqueue associated with the completion. On the contrary, the INIT_COMPLETION() call only reinits the flag. In case there was anything still stuck in the waitqueue, subsequent call to init_completion() would be able to create possible race condition. This patch uses the proper function and moves init_completion() into .probe() call of the driver, to be issued only once. Note that such scenario is impossible, since two threads can never enter the mxs_i2c_xfer_msg(), since whole this section is protected by mutex in I2C core. This by no means allows this issue to exit though. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>

2013-01-20module: fix missing module_mutex unlockLinus Torvalds
Commit 1fb9341ac348 ("module: put modules in list much earlier") moved some of the module initialization code around, and in the process changed the exit paths too. But for the duplicate export symbol error case the change made the ddebug_cleanup path jump to after the module mutex unlock, even though it happens with the mutex held. Rusty has some patches to split this function up into some helper functions, hopefully the mess of complex goto targets will go away eventually.

Balance pause/resume logic got broken by 5ac00add (went in into 3.8-rc1 as part of dev-replace merge). Offending commit took a stab at making mutually exclusive volume operations (add_dev, rm_dev, resize, balance, replace_dev) not block behind volume_mutex if another such operation is in progress and instead return an error right away. Balancing front-end relied on the blocking behaviour, so the fix is ugly, but short of a complete rework, it's the best we can do.

2013-01-19x86-32: Start out cr0 clean, disable paging before modifying cr3/4H. Peter Anvin
Patch 5a5a51db78e x86-32: Start out eflags and cr4 clean ... made x86-32 match x86-64 in that we initialize %eflags and %cr4 from scratch. This broke OLPC XO-1.5, because the XO enters the kernel with paging enabled, which the kernel doesn't expect. Since we no longer support 386 (the source of most of the variability in %cr0 configuration), we can simply match further x86-64 and initialize %cr0 to a fixed value -- the one variable part remaining in %cr0 is for FPU control, but all that is handled later on in initialization; in particular, configuring %cr0 as if the FPU is present until proven otherwise is correct and necessary for the probe to work. To deal with the XO case sanely, explicitly disable paging in %cr0 before we muck with %cr3, %cr4 or EFER -- those operations are inherently unsafe with paging enabled. NOTE: There is still a lot of 386-related junk in head_32.S which we can and should get rid of, however, this is intended as a minimal fix whereas the cleanup can be deferred to the next merge window.

2013-01-19ARM: DMA: Fix struct page iterator in dma_cache_maint() to work with sparsememRussell King
Subhash Jadavani reported this partial backtrace: Now consider this call stack from MMC block driver (this is on the ARMv7 based board): [<c001b50c>] (v7_dma_inv_range+0x30/0x48) from [<c0017b8c>] (dma_cache_maint_page+0x1c4/0x24c) [<c0017b8c>] (dma_cache_maint_page+0x1c4/0x24c) from [<c0017c28>] (___dma_page_cpu_to_dev+0x14/0x1c) [<c0017c28>] (___dma_page_cpu_to_dev+0x14/0x1c) from [<c0017ff8>] (dma_map_sg+0x3c/0x114) This is caused by incrementing the struct page pointer, and running off the end of the sparsemem page array. Fix this by incrementing by pfn instead, and convert the pfn to a struct page.

Commit ff3206b2450499203532af2505a7f6f8413e92c0 ('mtd: nand: onfi need to be probed in 8 bits mode') adds a WARN if the onfi probe is in 16 bits mode.

Commit d68cbdd4fb (mtd: physmap_of: allow to specify the mtd name for retro compatiblity) broke cmdline partitioning using dev_name() in the kernel command line. of_property_read_string() does not touch mtd_name when linux,mtd-name is not present in the device tree, which causes map.name to be set to a random value. Fix this by initializing mtd_name to NULL.

2013-01-19ACPI, APEI: Fixup incorrect 64-bit access width firmware bugLans Zhang
The bit width check was introduced by 15afae60 (ACPI, APEI: Fix incorrect APEI register bit width check and usage), and a fixup for incorrect 32-bit width memory address was given by f712c71 (ACPI, APEI: Fixup common access width firmware bug). Now there is a similar symptom: [Firmware Bug]: APEI: Invalid bit width + offset in GAR [0x12345000/64/0/3/0] Another bogus BIOS reports an incorrect 64-bit width in trigger table. Thus, apply to a similar workaround for 64-bit width memory address.

2013-01-18ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function callsJon Hunter
During the migration to the common clock framework, calls to the functions omap2xxx_clkt_vps_late_init() were not preserved for OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and "curr_prcm_set" to be uninitialised on boot. On reboot, this causes the following error message to be displayed because the appropriate MPU clock frequency (derived from sys_ck_rate) cannot be found. "Could not set MPU rate to 4294MHz" Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the OMAP2420 and OMAP2430 clock initialisation code.
