sysfs tries to keep dcache a strict subset of sysfs_dirent tree by shooting down dentries when a node is removed, that is, no negative dentry for sysfs. However, the lookup function returned NULL and thus created negative dentries when the target node didn't exist. Make sysfs_lookup() return ERR_PTR(-ENOENT) on lookup failure. This fixes the NULL dereference bug in sysfs_get_dentry() discovered by bluetooth rfcomm device moving around.

The compiler team did the hard work for this distilling a problem in large fortran application which showed up when applied to a 290MB input data set down to this instruction: ldfd f34=[r17],-8 Which they noticed incremented r17 by 0x10 rather than decrementing it by 8 when the value in r17 caused an unaligned data fault. I tracked it down to some bad instruction decoding in unaligned.c. The code assumes that the 'x' bit can determine whether the instruction is an "ldf" or "ldfp" ... which it is for opcode=6 (see table 4-29 on page 3:302 of the SDM). But for opcode=7 the 'x' bit is irrelevent, all variants are "ldf" instructions (see table 4-36 on page 3:306). Note also that interpreting the instruction as "ldfp" means that the "paired" floating point register (f35 in the example here) will also be corrupted. Signed-off-by: NTony Luck <tony.luck@intel.com>

In pata_legacy and pata_winbond we've got bugs - cpu_to_le16() instead of cpu_to_le32(). Fortunately, both affected suckers are VLB, thus l-e-only, so we might get away with that unless we hit it with slop == 3 (hadn't checked if playing with badly aligned sg could trigger that). Still buggy... Moreover, pata_legacy, pata_winbond and pata_qdi forgot to initialize pad on the write side of 32bit case in their ->data_xfer().

This patch restores the blackfin Hardware Performance Monitor Profiling support that was killed by the combining of instrumentation menus in commit 09cadedb. Since there seems to be no good reason to behave differently from other architectures, it now automatically selects the hardware performance counters whenever the profiling is activated. mach-common/irqpanic.c: pm_overflow calls pm_overflow_handler which is in oprofile/op_model_bf533.c. I doubt that setting HARDWARE_PM as "m" will work at all, since the pm_overflow_handler should be in the core kernel image because it is called by irqpanic.c. Therefore, I change HARDWARE_PM from a tristate to a bool. The whole arch/$(ARCH)/oprofile/ is built depending on CONFIG_OPROFILE. Since part of the HARDWARE_PM support files sits in this directory, it makes sense to also depend on OPROFILE, not only PROFILING. Since OPROFILE already depends on PROFILING, it is correct to only depend on OPROFILE only. Thanks to Adrian Bunk for finding this bug and providing an initial patch.

Commit 09cadedb ("Combine instrumentation menus in kernel/Kconfig.instrumentation") broke ARM profiling support, since ARM has some extra Kconfig options and doesn't just use the common OPROFILE/KPROBES config options. Rather than just revert the thing outright, or add ARM-specific knowledge to the generic Kconfig.instrumentation file (where the only and whole point was to be generic, not too architecture-specific), this just makes ARM not use the generic version, since it doesn't suit it. So create an arm-specific version of Kconfig.instrumentation instead, and use that.

In the current code, RTC_AIE doesn't work if the RTC relies on CONFIG_HPET_EMULATE_RTC because the code sets the RTC_AIE flag in hpet_set_rtc_irq_bit(). The interrupt handles does accidentally check for RTC_PIE and not RTC_AIE when comparing the time which was set in hpet_set_alarm_time(). I now verified on a test system here that without the patch applied, the attached test program fails on a system that has HPET with 2.6.24-rc7-default. That's not critical since I guess the problem has been there for several kernel releases, but as the fix is quite obvious. Configuration is CONFIG_RTC=y and CONFIG_HPET_EMULATE_RTC=y.

Denys Fedoryshchenko reported a bootup crash when he upgraded his system from 3GB to 4GB RAM: http://lkml.org/lkml/2008/1/7/9 the bug is due to HIGHMEM4G && SPARSEMEM kernels making pfn_to_page() to return an invalid pointer when the pfn is in a memory hole. The 256 MB PCI aperture at the end of RAM was not mapped by sparsemem, and hence the pfn was not valid. But set_highmem_pages_init() iterated this range without checking the pfn's validity first. this bug was probably present in the sparsemem code ever since sparsemem has been introduced in v2.6.13. It was masked due to HIGHMEM64G using larger memory regions in sparsemem_32.h: #ifdef CONFIG_X86_PAE #define SECTION_SIZE_BITS 30 #define MAX_PHYSADDR_BITS 36 #define MAX_PHYSMEM_BITS 36 #else #define SECTION_SIZE_BITS 26 #define MAX_PHYSADDR_BITS 32 #define MAX_PHYSMEM_BITS 32 #endif which creates 1GB sparsemem regions instead of 64MB sparsemem regions. So in practice we only ever created true sparsemem holes on x86 with HIGHMEM4G - but that was rarely used by distros. ( btw., we could probably save 2MB of mem_map[]s on X86_PAE if we reduced the sparsemem region size to 256 MB. ) Signed-off-by: NIngo Molnar <mingo@elte.hu> Acked-by: NThomas Gleixner <tglx@linutronix.de>

Commit 473980a9 added a call to clear the SLB shadow buffer before registering it. Unfortunately this means that we clear out the entries that slb_initialize has previously set in there. On POWER6, the hypervisor uses the SLB shadow buffer when doing partition switches, and that means that after the next partition switch, each non-boot CPU has no SLB entries to map the kernel text and data, which causes it to crash. This fixes it by reverting most of 473980a9 and instead clearing the 3rd entry explicitly in slb_initialize. This fixes the problem that 473980a9 was trying to solve, but without breaking POWER6.

Commit 5d2efba6 changed our iommu code so that it always uses an iommu page size of 4kB. That means with our current code, drivers may do a dma_map_sg() of a 64kB page and obtain a dma_addr_t that is only 4k aligned. This works fine in most cases except for some infiniband HW it seems, where they tell the HW about the page size and it ignores the low bits of the DMA address. This works around it by making our IOMMU code enforce a PAGE_SIZE alignment for mappings of objects that are page aligned in the first place and whose size is larger or equal to a page.

CERR reports errors detected during executing a command. This doesn't mean the error is tied to the command and can be recovered by just issuing it again. Many of the errors are fatal port-wide connditions including HSM violation, host bus error and ATA bus error and require freezing and port reset. The freezing part wasn't implemented previously. This used to be okay because port resets were scheduled anyway and EH eventually resets and recovers the port. With PMP support added, this is no longer true. The error condition and recover actions are attributed to the fan-out port and the host port condition isn't properly recovered leading to EH failures. This patch makes CERR errors which require resets to freeze the port. This will force host port reset and proper recovery.
