2010-12-28ueagle-atm: fix PHY signal initialization raceDan Williams
A race exists when initializing ueagle-atm devices where the generic atm device may not yet be created before the driver attempts to initialize it's PHY signal state, which checks whether the atm device has been created or not. This often causes the sysfs 'carrier' attribute to be '1' even though no signal has actually been found. uea_probe usbatm_usb_probe driver->bind (uea_bind) uea_boot kthread_run(uea_kthread) uea_kthread usbatm_atm_init uea_start_reset atm_dev_register UPDATE_ATM_SIGNAL UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if not, will not update the PHY signal state. Because of the race that does not always happen in time, and the PHY signal state remains ATM_PHY_SIG_FOUND even though no signal exists. To fix the race, just create the kthread during initialization, and only after initialization is complete, start the thread that reboots the device and initializes PHY state.

2010-12-28modpost: Fix address calculation in reloc_location()Olof Johansson
This patch fixes a segfault in modpost that is observed when the gold linker is used to link the input objects. The problem is that reloc_location (modpost.c) is computing the address of the relocation target incorrectly. Here, elf->hdr points to the beginning of the ELF file in memory, sechdr points to the relocation section header, section is the index of the section being relocated, and sechdrs[section].sh_offset would be the offset of that section, relative to the beginning of the ELF file. Adding elf->hdr + sechdrs[section].sh_offset gives you the address of the beginning of the section, and adding r->r_offset to that gives you the address of the location to be relocated. You do not need to subtract sechdrs[section].sh_addr from that -- the result of this is an address outside the file, and causes the segfault when addend_386_rel tries to dereference it. This bug is not observed when GNU ld is used to link the inputs. The object file ubuntu/omnibook/omnibook.o is the result of an ld -r of several other files. When GNU ld does an ld -r, it sets the vaddr field for each section to 0, but gold lays out the section addresses sequentially instead: Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] .text PROGBITS 00000000 000034 004794 00 AX 0 0 4 [ 2] .data PROGBITS 0000b9d0 0047c8 0009c0 00 WA 0 0 4 [ 3] .bss NOBITS 000162f8 005188 00013c 00 WA 0 0 4 [ 4] .rodata.str1.1 PROGBITS 00004f2d 0052c4 001b1a 01 AMS 0 0 1 [ 5] .init.text PROGBITS 00004794 006dde 0005fa 00 AX 0 0 1 [ 6] .exit.text PROGBITS 00004d8e 0073d8 00018a 00 AX 0 0 1 ... So the bug in the tool remained undiscovered because the section's vaddr always happened to be 0.

2010-12-27x86, paravirt: Use native_halt on a halt, not native_safe_haltCliff Wickman
halt() should use native_halt() safe_halt() uses native_safe_halt() If CONFIG_PARAVIRT=y, halt() is defined in arch/x86/include/asm/paravirt.h as static inline void halt(void) { PVOP_VCALL0(pv_irq_ops.safe_halt); } Otherwise (no CONFIG_PARAVIRT) halt() in arch/x86/include/asm/irqflags.h is static inline void halt(void) { native_halt(); } So it looks to me like the CONFIG_PARAVIRT case of using native_safe_halt() for a halt() is an oversight. Am I missing something? It probably hasn't shown up as a problem because the local apic is disabled on a shutdown or restart. But if we disable interrupts and call halt() we shouldn't expect that the halt() will re-enable interrupts.

2010-12-27perf probe: Fix short file name probe location reportingFranck Bui-Huu
After adding probes, perf-probe(1) reports the probes locations which include filenames for certain cases. But for short file names (whose length < 32), perf-probe didn't display the name correctly. It actually skipped the first character. Here's an example where 'icmp.c' was screwed: $ perf probe -n -a "icmp.c;sk=*" Add new events: probe:icmp_push_reply (on @cmp.c) probe:icmp_reply (on @cmp.c) probe:icmp_reply_1 (on @cmp.c) probe:icmp_send (on @cmp.c) probe:icmp_send_1 (on @cmp.c) probe:icmp_error (on @cmp.c) probe:icmp_error_1 (on @cmp.c) probe:icmp_error_2 (on @cmp.c) probe:icmp_error_3 (on @cmp.c) This patch fixes this bug in synthesize_perf_probe_point().

2010-12-27x86/microcode: Fix double vfree() and remove redundant pointer checks before ↵Jesper Juhl
vfree() In arch/x86/kernel/microcode_intel.c::generic_load_microcode() we have this: while (leftover) { ... if (get_ucode_data(mc, ucode_ptr, mc_size) || microcode_sanity_check(mc) < 0) { vfree(mc); break; } ... } if (mc) vfree(mc); This will cause a double free of 'mc'. This patch fixes that by just removing the vfree() call in the loop since 'mc' will be freed nicely just after we break out of the loop. There's also a second change in the patch. I noticed a lot of checks for pointers being NULL before passing them to vfree(). That's completely redundant since vfree() deals gracefully with being passed a NULL pointer. Removing the redundant checks yields a nice size decrease for the object file.

2010-12-25[media] v4l: soc-camera: fix multiple simultaneous user caseGuennadi Liakhovetski
A recent patch has introduced a regression, whereby a second open of an soc-camera video device breaks the running capture. This patch fixes this bug by guaranteeing, that video buffers get initialised only during the first open of the device node.

2010-12-25perf script: Fix event ordering settings to work with older kernelsArnaldo Carvalho de Melo
If we don't use .ordering_requires_timestamps we'll end up trying to order events with no timestamps when running on older kernels. Problem introduced in eac23d1c. After the last three fixes, perf scripting is back working, tested with new perf userspace on old and new (with sample_id_all) kernels.

2010-12-25spi / PM: Support dev_pm_opsMark Brown
Allow SPI drivers to use runtime PM and other dev_pm_ops features by implementing dev_pm_ops for the bus. The existing bus specific suspend and resume functions will be called if a driver does not provide dev_pm_ops allowing for transition to the new model.

2010-12-25perf record: Fix use of sample_id_all userspace with !sample_id_all kernelsArnaldo Carvalho de Melo
Check if parse_single_tracepoint_event has already asked for PERF_SAMPLE_TIME. This is kludgy but short term fix for problems introduced by eac23d1c that broke 'perf script' by having different sample_types when using multiple tracepoint events when we use a perf binary that tries to use sample_id_all on an older kernel. We need to move counter creation to perf_session, support different sample_types, etc. Ongoing work on the perf test infrastructure needs this so that we can create counters to monitor threads generating specific events, etc. Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Tom Zanussi <tzanussi@gmail.com> Cc: Torok Edwin <edwintorok@gmail.com> Cc: Ian Munsie <imunsie@au1.ibm.com> LKML-Reference: <new-submission> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
