2007-02-14[PATCH] sysctl: reimplement the sysctl proc supportEric W. Biederman2-4/+0
With this change the sysctl inodes can be cached and nothing needs to be done when removing a sysctl table. For a cost of 2K code we will save about 4K of static tables (when we remove de from ctl_table) and 70K in proc_dir_entries that we will not allocate, or about half that on a 32bit arch. The speed feels about the same, even though we can now cache the sysctl dentries :( We get the core advantage that we don't need to have a 1 to 1 mapping between ctl table entries and proc files. Making it possible to have /proc/sys vary depending on the namespace you are in. The currently merged namespaces don't have an issue here but the network namespace under /proc/sys/net needs to have different directories depending on which network adapters are visible. By simply being a cache different directories being visible depending on who you are is trivial to implement.

2007-02-14[PATCH] sysctl: factor out sysctl_head_next from do_sysctlEric W. Biederman1-0/+4
The current logic to walk through the list of sysctl table headers is slightly painful and implement in a way it cannot be used by code outside sysctl.c I am in the process of implementing a version of the sysctl proc support that instead of using the proc generic non-caching monster, just uses the existing sysctl data structure as backing store for building the dcache entries and for doing directory reads. To use the existing data structures however I need a way to get at them. [akpm@osdl.org: warning fix] Signed-off-by: Eric W.

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman1-2/+2
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

2007-02-14[PATCH] knfsd: add some new fsid typesNeilBrown3-38/+80
Add support for using a filesystem UUID to identify and export point in the filehandle. For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up too much room. For NFSv3+, we use the full 16 bytes, and possibly also a 64bit inode number for exports beneath the root of a filesystem. When generating an fsid to return in 'stat' information, use the UUID (hashed down to size) if it is available and a small 'fsid' was not specifically provided.

2007-02-14[PATCH] ia64: fix noncoherent DMA API so devres buildsRoland Dreier1-2/+13
On ia64, drivers/base/dma-mapping.c doesn't build because it calls dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be terminally broken; the calls end up generating errors like drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release': drivers/base/dma-mapping.c:32: error: 'struct ia64_machine_vector' has no member named 'platform_dma_free_coherent' because the multiple levels of macro expansion in <asm/dma-mapping.h> and <asm/machvec.h> end up turning a call to dma_free_noncoherent() into ia64_mv.platform_dma_free_coherent (instead of the intended ia64_mv.dma_free_coherent). This patch fixes this by converting dma_{alloc,free}_noncoherent() into inline functions that call the corresponding coherent functions, instead of trying to do this with macros.

2007-02-14[POWERPC] Use udbg_early_init() on ppc32David Gibson1-0/+1
udbg_early_init() is a function used on 64 bit systems, which initializes whichever early udbg backend is configured. This function is not called on 32-bit, however if btext early debug is enabled it does have an explicit, inline, #ifdef-ed assignment performing analagous initialization. This patch makes things more uniform by folding the btext initialization as an option into udbg_early_init() and calling that from the 32-bit setup path.

2007-02-13[PATCH] x86-64: update IO-APIC dest field to 8-bit for xAPICBenjamin Romer1-12/+2
On the Unisys ES7000/ONE system, we encountered a problem where performing a kexec reboot or dump on any cell other than cell 0 causes the system timer to stop working, resulting in a hang during timer calibration in the new kernel. We traced the problem to one line of code in disable_IO_APIC(), which needs to restore the timer's IO-APIC configuration before rebooting. The code is currently using the 4-bit physical destination field, rather than using the 8-bit logical destination field, and it cuts off the upper 4 bits of the timer's APIC ID. If we change this to use the logical destination field, the timer works and we can kexec on the upper cells. This was tested on two different cells (0 and 2) in an ES7000/ONE system. For reference, the relevant Intel xAPIC spec is kept at ftp://download.intel.com/design/chipsets/e8501/datashts/30962001.pdf, specifically on page 334.

2007-02-13[PATCH] x86: fix laptop bootup hang in init_acpi()Ingo Molnar1-1/+8
During kernel bootup, a new T60 laptop (CoreDuo, 32-bit) hangs about 10%-20% of the time in acpi_init(): Calling initcall 0xc055ce1a: topology_init+0x0/0x2f() Calling initcall 0xc055d75e: mtrr_init_finialize+0x0/0x2c() Calling initcall 0xc05664f3: param_sysfs_init+0x0/0x175() Calling initcall 0xc014cb65: pm_sysrq_init+0x0/0x17() Calling initcall 0xc0569f99: init_bio+0x0/0xf4() Calling initcall 0xc056b865: genhd_device_init+0x0/0x50() Calling initcall 0xc056c4bd: fbmem_init+0x0/0x87() Calling initcall 0xc056dd74: acpi_init+0x0/0x1ee() It's a hard hang that not even an NMI could punch through! Frustratingly, adding printks or function tracing to the ACPI code made the hangs go away ... After some time an additional detail emerged: disabling the NMI watchdog made these occasional hangs go away. So i spent the better part of today trying to debug this and trying out various theories when i finally found the likely reason for the hang: if acpi_ns_initialize_devices() executes an _INI AML method and an NMI happens to hit that AML execution in the wrong moment, the machine would hang. (my theory is that this must be some sort of chipset setup method doing stores to chipset mmio registers?) Unfortunately given the characteristics of the hang it was sheer impossible to figure out which of the numerous AML methods is impacted by this problem. As a workaround i wrote an interface to disable chipset-based NMIs while executing _INI sections - and indeed this fixed the hang. I did a boot-loop of 100 separate reboots and none hung - while without the patch it would hang every 5-10 attempts. Out of caution i did not touch the nmi_watchdog=2 case (it's not related to the chipset anyway and didnt hang). I implemented this for both x86_64 and i686, tested the i686 laptop both with nmi_watchdog=1 [which triggered the hangs] and nmi_watchdog=2, and tested an Athlon64 box with the 64-bit kernel as well. Everything builds and works with the patch applied.
