2006-04-11[PATCH] ipmi: fix event queue limitCorey Minyard
The event handler mechanism in the IPMI driver had a limit on the number of received events, but the counts were not being updated. Update the counts to impose a limit. This is not a critical fix, as this function (the sending of the events) has to be turned on by the user, anyway. This avoids problems if they forget to turn it back off.

2006-04-11[PATCH] MPBL0010 driver sysfs permissions wide openMark Bellon
The MPBL0010 Telco clock driver (drivers/char/tlclk.c) uses 0222 (anyone can write) permissions on its writable sysfs entries. Alter the permissions to 0220 (owner and group can write). The use case for this driver is to configure the fail over behavior of the clock hardware. That should be done by the more privileged users.

2006-04-11[PATCH] ptmx: fix duplicate idr_removePaul Fulghum
Remove duplicate call to idr_remove() in ptmx_open. Error during open can result in call to release_dev() followed by call to idr_remove(). release_dev already calls idr_remove so the second call can cause a stack dump in idr_remove()->sub_remove() flagging an attempt to release an already released entry. I reproduces this on a machine with a misconfigured X server (attempting to restart multiple times rapidly) getting the same error as the 1st link below. This also seems to be related to: http://marc.theaimsgroup.com/?l=selinux&m=110536513426735&w=2 http://marc.theaimsgroup.com/?l=selinux&m=110596994916785&w=2 The stack dump can occur on close (as well as open) as shown in the 1st instance above, possible from something like: process A - open (index=0), open fail to out1, release_dev calls idr_remove (index 0), down(sem) sleeps process B - open (index=0), open OK (idr allocated) process A - wake and call idr_remove on index 0 ... process B - close, release_dev, stack dump on idr_remove (index=0) because entry already removed Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-04-11[PATCH] Remove blkmtdJoern Engel
Remove the blkmtd driver. - An alternative exists (block2mtd) that hasn't had bug report for > 1 year. - Most embedded people tend to use ancient kernels with custom patches from mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts them too much. - It's in the way of klibc. The problems caused by pulling blkmtd support are fairly low, while the problems caused by delaying klibc can be fairly substantial. At best, this would be a severe burden on hpa's time.

2006-04-11[PATCH] md: make sure 64bit fields in version-1 metadata are 64-bit alignedNeilBrown
reshape_position is a 64bit field that was not 64bit aligned. So swap with new_level. NOTE: this is a user-visible change. However: - The bad code has not appeared in a released kernel - This code is still marked 'experimental' - This only affects version-1 superblock, which are not in wide use - These field are only used (rather than simply reported) by user-space tools in extemely rare circumstances : after a reshape crashes in the first second of the reshape process. So I believe that, at this stage, the change is safe. Especially if people heed the 'help' message on use mdadm-2.4.1.

Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out.

2006-04-10IB/mthca: Disable tuning PCI read burst sizeMichael S. Tsirkin
The PCI spec recommends against drivers playing with a device's PCI read burst size, and says that systems software should configure it. And we actually have users that report that changing it from the default set by BIOS hurts performance and/or stability for them. On the other hand, the Mellanox Programmer's Reference Manual recommends turning it up all the way to the maximum value. Some tests conducted here in the lab do not show performance improvement from this tuning, but this might be just me. As a work-around, make this tuning an option, off by default (safe value), with an eye towards removing it completely one day if no one complains. Signed-off-by: Michael S.

2006-04-10IPoIB: Wait for join to finish before freeing mcast structEli Cohen

2006-04-10IB: simplify static rate encodingJack Morgenstein
Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-04-09[TG3]: Speed up SRAM access (2nd version)Michael Chan
Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. David Miller informed me that an earlier version of the patch caused problems on sparc64 systems with built-in tg3 chips. This version fixes the problem by excluding all SUN built-in tg3 chips from doing MMIO SRAM access. TG3_FLAG_EEPROM_WRITE_PROT is also set unconditionally when TG3_FLG2_SUN_570X is set. This should be sane as all SUN chips are built-in and do not require Vaux switching. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
