Limit the number of recoveries from a NIC hw watchdog reset to 1 by default. It enables detection of defective NICs immediately since these memory parity errors are expected to happen very rarely (less than once per century*NIC).

NetXen: Fix incorrect link status even with switch turned OFF. NetXen driver failed to accurately indicate when a link is up or down. This was encountered during failover testing, when the first port indicated that the link was up even when the 10G switch it was assigned to in the Bladecenter was turned off completely.

This reverts commit d52df4a3. This patch attempted to fix e100 for non-cache coherent memory architectures by using the cb style code that eepro100 had and using the EL and s bits from the RFD list. Unfortunately the hardware doesn't work exactly like this and therefore this patch actually breaks e100. Reverting the change brings it back to the previously known good state for 2.6.22. The pending rewrite in progress to this code can then be safely merged later. Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Support for configuring RGMII-ID (RGMII with internal delay) mode on the 88e1111 and 88e1145. Ucc_geth on MPC8360EMDS(the main user of ucc_geth) is broken after changed to use phylib. It is fixed by adding this internal delay. Also renamed 88e1111s -> 88e1111 (no references to an 88e1111s part were found), and fixed some whitespace.

NetXen: Fix initialization and subsequent ping issue on 3.4.19 firmware This patch fixes the ping problem seen X/PBlades after the adapter's firmware was moved to 3.4.19. After configured interface up, ping failed. NetXen adapter couldn't accept ARP broadcast packet. Manual addition of MAC address in the ARP table, made ping work. NetXen adapter should finish initilization after system boot. But looks NetXen adapter didn't initilization correctly after system boot up. So have to re-load the firmware again in probe routine. Also re-initilization netxen_config_0 and netxen_config_1 registers.

Currently, ibmveth maintains several rx buffer pools, which can be modified through sysfs. By default, pools are not allocated by default such that jumbo frames cannot be supported without first activating larger rx buffer pools. This results in failures when attempting to change the mtu. This patch makes ibmveth automatically allocate these larger buffer pools when the mtu is changed. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Add a prefix string parameter. Callers are responsible for any string length/alignment that they want to see in the output. I.e., callers should pad strings to achieve alignment if they want that. Add rowsize parameter. This is the number of raw data bytes to be printed per line. Must be 16 or 32. Add a groupsize parameter. This allows callers to dump values as 1-byte, 2-byte, 4-byte, or 8-byte numbers. Default is 1-byte numbers. If the total length is not an even multiple of groupsize, 1-byte numbers are printed. Add an "ascii" output parameter. This causes ASCII data output following the hex data output. Clean up some doc examples. Align the ASCII output on all lines that are produced by one call. Add a new interface, print_hex_dump_bytes(), that is a shortcut to print_hex_dump(), using default parameter values to print 16 bytes in byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.

We aren't sampling for holes in memory. Thus we encounter a section hole with empty section map pointer for SPARSEMEM and OOPs for show_mem. This issue has been seen in 2.6.21, current git and current mm. The patch below is for mainline and mm. It was boot tested for SPARSEMEM, current VMEMMAP of Andy's in mm ml and DISCONTIGMEM. A slightly different patch will be posted to stable for 2.6.21. Previous to commit f0a5a58a memory_present was called for node_start_pfn to node_end_pfn. This would cover the hole(s) with reserved pages and valid sections. Most SPARSEMEM supported arches do a pfn_valid check in show_mem before computing the page structure address. This issue was brought to my attention on IRC by Arnaldo Carvalho de Melo. Thanks to Arnaldo for testing.

1. New entries can be added to tsk->pi_state_list after task completed exit_pi_state_list(). The result is memory leakage and deadlocks. 2. handle_mm_fault() is called under spinlock. The result is obvious. 3. results in self-inflicted deadlock inside glibc. Sometimes futex_lock_pi returns -ESRCH, when it is not expected and glibc enters to for(;;) sleep() to simulate deadlock. This problem is quite obvious and I think the patch is right. Though it looks like each "if" in futex_lock_pi() got some stupid special case "else if". :-) 4. sometimes futex_lock_pi() returns -EDEADLK, when nobody has the lock. The reason is also obvious (see comment in the patch), but correct fix is far beyond my comprehension. I guess someone already saw this, the chunk: if (rt_mutex_trylock(&q.pi_state->pi_mutex)) ret = 0; is obviously from the same opera. But it does not work, because the rtmutex is really taken at this point: wake_futex_pi() of previous owner reassigned it to us. My fix works. But it looks very stupid. I would think about removal of shift of ownership in wake_futex_pi() and making all the work in context of process taking lock. From: Thomas Gleixner <tglx@linutronix.de> Fix 1) Avoid the tasklist lock variant of the exit race fix by adding an additional state transition to the exit code. This fixes also the issue, when a task with recursive segfaults is not able to release the futexes. Fix 2) Cleanup the lookup_pi_state() failure path and solve the -ESRCH problem finally. Fix 3) Solve the fixup_pi_state_owner() problem which needs to do the fixup in the lock protected section by using the in_atomic userspace access functions. This removes also the ugly lock drop / unqueue inside of fixup_pi_state() Fix 4) Fix a stale lock in the error path of futex_wake_pi() Added some error checks for verification. The -EDEADLK problem is solved by the rtmutex fixups.

Alexey Kuznetsov found some problems in the pi-futex code. The major problem is a stale return value in rt_mutex_slowlock(): When the pi chain walk returns -EDEADLK, but the waiter was woken up during the phases where the locks were dropped, the rtmutex could be acquired, but due to the stale return value -EDEADLK returned to the caller. Reset the return value in the retry path.

sata_promise uses two different command modes - packet and TF. Packet mode is intelligent low-overhead mode while TF is the same old taskfile interface. As with other advanced interface (ahci/sil24), ATA_TFLAG_POLLING has no effect in packet mode. However, PIO commands are issued using TF interface in polling mode, so pdc_interrupt() considers interrupts spurious if ATA_TFLAG_POLLING is set. This is broken for polling NODATA commands because command is issued using packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING. Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued using TF interface if ATA_TFLAG_POLLING is set. This patch fixes detection failure introduced by polling SETXFERMODE.

Instead of returning the smallest available object return ZERO_SIZE_PTR. A ZERO_SIZE_PTR can be legitimately used as an object pointer as long as it is not deferenced. The dereference of ZERO_SIZE_PTR causes a distinctive fault. kfree can handle a ZERO_SIZE_PTR in the same way as NULL. This enables functions to use zero sized object. e.g. n = number of objects. objects = kmalloc(n * sizeof(object)); for (i = 0; i < n; i++) objects[i].x = y; kfree(objects); Signed-off-by: Christoph Lameter <clameter@sgi.com> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
