The earlier crash dump fix on x86_64 depended on patches in -mm which are intended for post-2.6.23. Without those, it broke the build when it went into 2.6.23-rc5. This changes the field references in ELF_CORE_COPY_REGS back to those still used in mainline.

In the case when an nmi gets stucks the endflag stays equal to zero. This causes the busy looping on other cpus to continue, even though the nmi test is done. On my machine with out the change below the system would hang right after check_nmi_watchdog(). The change below just sets endflag prior to checking if the test was successful or not.

The CLFLUSH for the modified code line in text_poke was supposed to speed up CPU recovery.

Fix the NMI watchdog on Intel CoreDuo processor where the kernel would get stuck during boot. The issue is related to errata AE49, where the PERFEVTSEL1 counter does not have a working enable bit. Thus it is not possible to use it for NMI. The patch creates a dedicated wd_ops for CoreDuo which falls back to using PERFEVTSEL0. The other Intel processors supporting the architectural PMU will keep on using PERFEVTSEL1 as this allows other subsystems, such as perfmon, to use PERFEVTSEL0 for PEBS monitoring in particular. Bug initially reported by Daniel Walker.

fsid_source decided where to get the 'fsid' number to return for a GETATTR based on the type of filehandle. It can be from the device, from the fsid, or from the UUID. It is possible for the filehandle to be inconsistent with the export information, so make sure the export information actually has the info implied by the value returned by fsid_source.

Recent changes in NFSd cause a directory which is mounted-on to not appear properly when the filesystem containing it is exported. *exp_get* now returns -ENOENT rather than NULL and when commit 5d3dbbea removed the NULL checks, it didn't add a check for -ENOENT.

When PTRACE_SYSCALL was used and then PTRACE_DETACH is used, the TIF_SYSCALL_TRACE flag is left set on the formerly-traced task. This means that when a new tracer comes along and does PTRACE_ATTACH, it's possible he gets a syscall tracing stop even though he's never used PTRACE_SYSCALL. This happens if the task was in the middle of a system call when the second PTRACE_ATTACH was done. The symptom is an unexpected SIGTRAP when the tracer thinks that only SIGSTOP should have been provoked by his ptrace calls so far. A few machines already fixed this in ptrace_disable (i386, ia64, m68k). But all other machines do not, and still have this bug. On x86_64, this constitutes a regression in IA32 compatibility support. Since all machines now use TIF_SYSCALL_TRACE for this, I put the clearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather than adding it to every other machine's ptrace_disable.

Fix "lost" interrupt problem when using dma with CD/DVD drives in some configurations. This problem can make installing linux from media impossible for distro's that have switched to libata-only configurations. The simple fix is to eliminate the use of dma for reading drive status, etc, by checking the number of bytes to transferred. This change will only affect the behavior of atapi devices, not disks.

Following a strict interpretation the empty definition of irq_enable_hazard has always been a bug - but an intentional one because it didn't bite. This has now changed, for uniprocessor kernels mm/slab.c:do_drain() [...] on_each_cpu(do_drain, cachep, 1, 1); check_irq_on(); [...] may be compiled into a mtc0 c0_status; mfc0 c0_status sequence resulting in a back-to-back hazard.

Previously, ibmebus derived a device's bus_id from its location code. The location code is not guaranteed to be unique, so we might get bus_id collisions if two devices share the same location code. The OFDT full_name, however, is unique, so we use that instead (truncating it on the left if it is too long).

On PS3, A storage device may show up in the repository before the hypervisor has finished probing: - If its type is not yet known, it shows up as PS3_DEV_TYPE_STOR_DUMMY, - If its regions are being probed, it shows up as having zero regions. If any of these happen, consider the device not yet present. The storage probe thread will retry later. This fixes the timing-dependent problem where a kernel booted from FLASH ROM sometimes cannot find the hard disk.

At present, running any SPE program on the ps3 will trigger a BUG_ON when spufs_run_spu tries to clear the master run control bit, as lv1 does not make the master run control available to Linux. This change makes SPE apps work again by disabling changes to the master run control on PS3. Although we don't have the facility to disable a SPE with supervisor-level privileges, it's better than hitting the BUG_ON unconditionally.

The Cell BE Architecture spec states that the SPU MFC Class 0 interrupt is edge-triggered. The current spu interrupt handler assumes this behavior and does not clear the interrupt status. The PS3 hypervisor visualizes all SPU interrupts as level, and on return from the interrupt handler the hypervisor will deliver a new virtual interrupt for any unmasked interrupts which for which the status has not been cleared. This fix clears the interrupt status in the interrupt handler.

This fixes a bug in the way i2c-algo-bit handles I2C_M_RECV_LEN, used to implement i2c_smbus_read_block_data(). Previously, in the absence of PEC (rarely used!) it would NAK the "length" byte: S addr Rd [A] [length] NA That prevents the subsequent data bytes from being read: S addr Rd [A] [length] { A [data] }* NA The primary fix just reorders two code blocks, so the length used in the "should I NAK now?" check incorporates the data which it just read from the slave device. However, that move also highlighted other fault handling glitches. This fixes those by abstracting the RX path ack/nak logic, so it can be used in more than one location. Also, a few CodingStyle issues were also resolved. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
