2009-12-15NFSv4: Fix a regression in the NFSv4 state managerTrond Myklebust
Commit 5601a00d671fe89f9b087513244abcd08ad67e7d (nfs: run state manager in privileged mode) introduces a regression in the NFSv4 code when compiled with CONFIG_NFS_V4_1. The calls to nfs4_end_drain_session() from the main loop in nfs4_state_manager() Oops due to the lack of an NFSv4.1 session when running NFSv4.0. The fix is to move those two calls back into nfs41_init_clientid() and nfs4_reset_session(). The calls to nfs4_end_drain_session() that remain inside nfs4_state_manager() are safe, since the NFSv4.0 code will never set the NFS4CLNT_SESSION_DRAINING bit.

2009-12-15ipmi: add PNP discovery (ACPI namespace via PNPACPI)Bjorn Helgaas
This allows ipmi_si_intf.c to claim IPMI devices described in the ACPI namespace. Using PNP makes it simpler to parse the IRQ/IO/memory resources of the device. We look at any SPMI tables before looking for devices in the namespace. This is based on ipmi_pci_probe().

2009-12-15ipmi: refer to table as "SPMI", not "ACPI"Bjorn Helgaas
This discovery method uses the SPMI table, not the ACPI namespace. In the future, we will look in the namespace, so let's refer to the table as "SPMI" and save "ACPI" for the namespace. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-12-15PNP: add interface to retrieve ACPI device from a PNPACPI deviceBjorn Helgaas
Add pnp_acpi_device(pnp_dev), which takes a PNP device and returns the associated ACPI device (or NULL, if the device is not a PNPACPI device). This allows us to write a PNP driver that can manage both traditional PNPBIOS and ACPI devices, treating ACPI-only functionality as an optional extension.

2009-12-15NFSv4: Release the sequence id before restarting a CLOSE rpc callTrond Myklebust
If the CLOSE or OPEN_DOWNGRADE call triggers a state recovery, and has to be resent, then we must release the seqid. Otherwise the open recovery will wait for the close to finish, which causes a deadlock. This is mainly a NFSv4.1 problem, although it can theoretically happen with NFSv4.0 too, in a OPEN_DOWNGRADE situation. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2009-12-15PM: Add initcall_debug style timing for suspend/resumeArjan van de Ven
In order to diagnose overall suspend/resume times, we need basic instrumentation to break down the total time into per device timing, similar to initcall_debug. This patch adds the basic timing instrumentation, needed for a scritps/bootgraph.pl equivalent or humans.

2009-12-15x86: Fix kprobes build with non-gawk awkJonathan Nieder
The instruction attribute table generator fails when run by mawk or original-awk: $ mawk -f arch/x86/tools/gen-insn-attr-x86.awk \ arch/x86/lib/x86-opcode-map.txt > /dev/null Semantic error at 240: Second IMM error $ echo $? 1 Line 240 contains "c8: ENTER Iw,Ib", which indicates that this instruction has two immediate operands, the second of which is one byte. The script loops through the immediate operands using a for loop. Unfortunately, there is no guarantee in awk that a for (variable in array) loop will return the indices in increasing order. Internally, both original-awk and mawk iterate over a hash table for this purpose, and both implementations happen to produce the index 2 before 1. The supposed second immediate operand is more than one byte wide, producing the error. So loop over the indices in increasing order instead. As a side-effect, with mawk this means the silly two-entry hash table never has to be built.

2009-12-15perf probe: Cleanup struct session in builtin-probe.cMasami Hiramatsu

2009-12-15perf_events: Fix perf_event_attr layoutPeter Zijlstra
The miss-alignment of bp_addr created a 32bit hole, causing different structure packings on 32 and 64 bit machines. Fix that by moving __reserve_2 into that hole. Further, remove the useless struct and redundant __bp_reserve muck.

2009-12-15nfsd: restrict filehandles accepted in V4ROOT caseSteve Dickson
On V4ROOT exports, only accept filehandles that are the *root* of some export. This allows mountd to allow or deny access to individual directories and symlinks on the pseudofilesystem. Note that the checks in readdir and lookup are not enough, since a malicious host with access to the network could guess filehandles that they weren't able to obtain through lookup or readdir.
