Fix the two section mismatch warnings below. This fixes two real bugs since the code which has __exit annotations may already be gone when it is called. WARNING: vmlinux.o(.init.text+0x1cc4a): Section mismatch in reference from the function init_QDIO() to the function .exit.text:qdio_setup_exit() The function __init init_QDIO() references a function __exit qdio_setup_exit(). This is often seen when error handling in the init function uses functionality in the exit path.

2008-08-01[S390] Optimize storage key operations for anon pagesMartin Schwidefsky
For anonymous pages without a swap cache backing the check in page_remove_rmap for the physical dirty bit in page_remove_rmap is unnecessary. The instructions that are used to check and reset the dirty bit are expensive. Removing the check noticably speeds up process exit. In addition the clearing of the dirty bit in __SetPageUptodate is pointless as well. With these two changes there is no storage key operation for an anonymous page anymore if it does not hit the swap space. The micro benchmark which repeatedly executes an empty shell script gets about 5% faster. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2008-08-01[S390] nohz/sclp: disable timer on synchronous waits.Heiko Carstens
sclp_sync_wait wait synchronously for an sclp interrupt and disables timer interrupts. However on the irq enter paths there is an extra check if a timer interrupt would be due and calls the timer callback. This would schedule softirqs in the wrong context.

2008-08-01[S390] ipl: Reboot from alternate device does not work when booting from fileMichael Holzheu
During startup we check if diag308 works using diag 308 subcode 6, which stores the actual ipl information. This fails with rc = 0x102, if the system has been ipled from the HMC using load from CD or load from file. In the case of rc = 0x102 we have to assume that diag 308 is working, since it still can be used to ipl from an alternative device.

2008-08-01kgdb: fix gdb serial thread queriesJason Wessel
The command "info threads" did not work correctly with kgdb. It would result in a silent kernel hang if used. This patach addresses several problems. - Fix use of deprecated NR_CPUS - Fix kgdb to not walk linearly through the pid space - Correctly implement shadow pids - Change the threads per query to a #define - Fix kgdb_hex2long to work with negated values The threads 0 and -1 are reserved to represent the current task. That means that CPU 0 will start with a shadow thread id of -2, and CPU 1 will have a shadow thread id of -3, etc... From the debugger you can switch to a shadow thread to see what one of the other cpus was doing, however it is not possible to execute run control operations on any other cpu execept the cpu executing the kgdb_handle_exception().

2008-08-01kgdb: fix kgdb_validate_break_address to perform a mem writeJason Wessel
A regression to the kgdb core was found in the case of using the CONFIG_DEBUG_RODATA kernel option. When this option is on, a breakpoint cannot be written into any readonly memory page. When an external debugger requests a breakpoint to get set, the kgdb_validate_break_address() was only checking to see if the address to place the breakpoint was readable and lacked a write check. This patch changes the validate routine to try reading (via the breakpoint set request) and also to try immediately writing the break point. If either fails, an error is correctly returned and the debugger behaves correctly. Then an end user can make the descision to use hardware breakpoints. Also update the documentation to reflect that using CONFIG_DEBUG_RODATA will inhibit the use of software breakpoints. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
2008-08-01kgdb: remove the requirement for CONFIG_FRAME_POINTERJason Wessel

2008-08-01Fix rename of at91_nand -> atmel_nandPieter du Preez
Structs called at91_nand_data where renamed to atmel_nand_data and configs called *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL*. This was unfortunately not done consistently, causing NAND chips not being initialised on several ARM boards. I am aware that the author of the original change did not rename MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example. All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order to keep naming consistency. This patch was only tested on a MACH_SAM9_L9260, as this is the only ARM board I have to my disposal.

2008-07-31tcp: MD5: Fix MD5 signatures on certain ACK packetsAdam Langley
I noticed, looking at tcpdumps, that timewait ACKs were getting sent with an incorrect MD5 signature when signatures were enabled. I broke this in 49a72dfb8814c2d65bd9f8c9c6daf6395a1ec58d ("tcp: Fix MD5 signatures for non-linear skbs"). I didn't take into account that the skb passed to tcp_*_send_ack was the inbound packet, thus the source and dest addresses need to be swapped when calculating the MD5 pseudoheader.

2008-07-31ipv6: Fix ip6_xmit to send fragments if ipfragok is trueWei Yongjun
SCTP used ip6_xmit() to send fragments after received ICMP packet too big message. But while send packet used ip6_xmit, the skb->local_df is not initialized. So when skb if enter ip6_fragment(), the following code will discard the skb. ip6_fragment(...) { if (!skb->local_df) { ... return -EMSGSIZE; } ... } SCTP do the following step: 1. send packet ip6_xmit(skb, ipfragok=0) 2. received ICMP packet too big message 3. if PMTUD_ENABLE: ip6_xmit(skb, ipfragok=1) This patch fixed the problem by set local_df if ipfragok is true.

2008-07-31ipvs: Move userspace definitions to include/linux/ip_vs.hJulius Volz
Current versions of ipvsadm include "/usr/src/linux/include/net/ip_vs.h" directly. This file also contains kernel-only definitions. Normally, public definitions should live in include/linux, so this patch moves the definitions shared with userspace to a new file, "include/linux/ip_vs.h". This also removes the unused NFC_IPVS_PROPERTY bitmask, which was once used to point into skb->nfcache. To make old ipvsadms still compile with this, the old header file includes the new one.

Clean up and simplify the device initialization function: * Degrade error messages to warnings - what they really are. * Stop warning about VxI mode, we don't really care. * Drop comment about lack of limit initialization - that's the standard way, all hardware monitoring drivers do that. * Only read the configuration register once. * Only write back to the configuration register if needed. * Don't attempt to clear the lock bit, it locks itself to 1. * Move the function to before it's called, so that we no longer need to forware declare it.

2008-07-31hwmon: (lm75) add new-style driver bindingDavid Brownell
More LM75 updates: - Teach the LM75 driver to use new-style driver binding: * Create a second driver struct, using new-style driver binding methods cribbed from the legacy code. * Add a MODULE_DEVICE_TABLE (for "newER-style binding") * The legacy probe logic delegates its work to this new code. * The legacy driver now uses the name "lm75_legacy". - More careful initialization. Chips are put into 9-bit mode so the current interconversion routines will never fail. - Save the original chip configuration, and restore it on exit. (Among other things, this normally turns off the mode where the chip is constantly sampling ... and thus saves power.) So the new-style code should catch all chips that boards declare, while the legacy code catches others. This particular coexistence strategy may need some work yet ... legacy modes might best be set up explicitly by some tool not unlike "sensors-detect". (Or else completely eradicated...)

One driver binding function moved out of the attribute section, as did the driver struct itself. - Minor tweaks to legacy probe logic: correct a comment, and remove a pointless variable. - Whitespace, linelength, and comment fixes.

2008-07-31netdev: Fix lockdep warnings in multiqueue configurations.David S. Miller
When support for multiple TX queues were added, the netif_tx_lock() routines we converted to iterate over all TX queues and grab each queue's spinlock. This causes heartburn for lockdep and it's not a healthy thing to do with lots of TX queues anyways. So modify this to use a top-level lock and a "frozen" state for the individual TX queues.
