2006-02-10[PATCH] tty buffering stall fixPaul Fulghum3-2/+8
Prevent stalled processing of received data when a driver allocates tty buffer space but does not immediately follow the allocation with more data and a call to schedule receive tty processing. (example: hvc_console) This bug was introduced by the first locking patch for the new tty buffering.

2006-02-10[PATCH] x86: don't initialise cpu_possible_map to all onesAndrew Morton1-1/+1
Initialising cpu_possible_map to all-ones with CONFIG_HOTPLUG_CPU means that a) All for_each_cpu() loops will iterate across all NR_CPUS CPUs, rather than over possible ones. That can be quite expensive. b) Soon we'll be allocating per-cpu areas only for possible CPUs. So with CPU_MASK_ALL, we'll be wasting memory. I also switched voyager over to not use CPU_MASK_ALL in the non-CPU-hotplug case. Should be OK.. I note that parisc is also using CPU_MASK_ALL. Suggest that it stop doing that.

2006-02-10[PATCH] kexec: fix in free initrd when overlapped with crashkernel regionHaren Myneni1-0/+1
It is possible that the reserved crashkernel region can be overlapped with initrd since the bootloader sets the initrd location. When the initrd region is freed, the second kernel memory will not be contiguous. The Kexec_load can cause an oops since there is no contiguous memory to write the second kernel or this memory could be used in the first kernel itself and may not be part of the dump. For example, on powerpc, the initrd is located at 36MB and the crashkernel starts at 32MB. The kexec_load caused panic since writing into non-allocated memory (after 36MB). We could see the similar issue even on other archs. One possibility is to move the initrd outside of crashkernel region. But, the initrd region will be freed anyway before the system is up. This patch fixes this issue and frees only regions that are not part of crashkernel memory in case overlaps. Signed-off-by: Haren Myneni <haren@us.ibm.com> Acked-by: "Eric W.

2006-02-10[PATCH] libata: implement ata_scsi_timed_out()Tejun Heo1-0/+1
Implement ata_scsi_timed_out(), to be used as scsi_host_template->eh_timed_out callback for all libata drivers. Without this function, the following race exists. If a qc completes after SCSI timer expires but before libata EH kicks in, the qc gets completed but the scsicmd still gets passed to libata EH resulting in ->eng_timeout invocation with NULL qc, which none is handling properly. This patch makes sure that scmd and qc share the same lifetime. Original idea from Jeff Garzik <jgarzik@pobox.com>.

2006-02-09[NETLINK]: Fix a severe bugAlexey Kuznetsov1-1/+2
netlink overrun was broken while improvement of netlink. Destination socket is used in the place where it was meant to be source socket, so that now overrun is never sent to user netlink sockets, when it should be, and it even can be set on kernel socket, which results in complete deadlock of rtnetlink. Suggested fix is to restore status quo passing source socket as additional argument to netlink_attachskb(). A little explanation: overrun is set on a socket, when it failed to receive some message and sender of this messages does not or even have no way to handle this error. This happens in two cases: 1. when kernel sends something. Kernel never retransmits and cannot wait for buffer space. 2. when user sends a broadcast and the message was not delivered to some recipients.

Patch from Nicolas Pitre Since: if (unlikely(__res || __ex_flag)) produces worse code on ARM than: if (unlikely(__res | __ex_flag)) I therefore made it more explicit: __res |= __ex_flag; if (unlikely(__res != 0)) so it is not seen as a typo again. Also made everything static inline rather than macros for better readability (both produce the same code after all). And finally added missing \t from multi-line assembly code.

2006-02-08[PATCH] block: implement elv_insert and use it (fix ordcolor flipping bug)Tejun Heo1-0/+1
q->ordcolor must only be flipped on initial queueing of a hardbarrier request. Constructing ordered sequence and requeueing used to pass through __elv_add_request() which flips q->ordcolor when it sees a barrier request. This patch separates out elv_insert() from __elv_add_request() and uses elv_insert() when constructing ordered sequence and requeueing. elv_insert() inserts the given request at the specified position and does nothing else.

2006-02-07[PATCH] powerpc: Thermal control for dual core G5sBenjamin Herrenschmidt1-0/+5
This patch adds a windfarm module, windfarm_pm112, for the dual core G5s (both 2 and 4 core models), keeping the machine from getting into vacuum-cleaner mode ;) For proper credits, the patch was initially written by Paul Mackerras, and slightly reworked by me to add overtemp handling among others. The patch also removes the sysfs attributes from windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm core to automagically expose attributes for sensor & controls.
