* [IA64] SGI SN drivers: don't report !sn2 hardware as an errorBjorn Helgaas2006-03-07

* [PATCH] Add missing ifdef for VIA RNG codeMark Brown2006-03-03
| | | | | | | | | | | Almost all the code for the VIA RNG is guarded with __i386__ #ifdefs, the only exception being the enumeration of RNG types which is used to index into the rng_vector ops array. This patch adds an ifdef around that for consistency and since the guard makes a difference when adding new RNG types on non-i386 hardware.

* [PATCH] Fix Specialix SX corruptionMarc Zyngier2006-02-27
| | | | | | | | | | | | | | | | | | | | With the latest kernels, I experienced some strange corruption, some '*****' being randomly inserted in the character flow, like this: ashes:~# ashes:~# a*******shes:~# ashes:~# ashes:~# Further investigation shows that the problem was introduced during Alan's "TTY layer buffering revamp" patch, the amount of data to be copied being reduced after buffer allocation. Moving the count fixup around solves the problem.

* [PATCH] Fix race condition in hvc console.Michal Ostrowski2006-02-23
| | | | | | | | | | | | | | | tty_schedule_flip() would schedule a thread that would call flush_to_ldisc(). If tty_buffer_request_room() gets called prior to that thread running -- which is likely in this loop in hvc_poll(), it would set the active flag in the tty buffer and consequently flush_to_ldisc() would ignore it. The result is that input on the hvc console is not processed. This fix calls tty_flip_buffer_push (and flags the tty as "low_latency"). The push to the ldisc thus happens synchronously.

* | | [PATCH] Terminate process that fails on a constrained allocationChristoph Lameter2006-02-20
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some allocations are restricted to a limited set of nodes (due to memory policies or cpuset constraints). If the page allocator is not able to find enough memory then that does not mean that overall system memory is low. In particular going postal and more or less randomly shooting at processes is not likely going to help the situation but may just lead to suicide (the whole system coming down). It is better to signal to the process that no memory exists given the constraints that the process (or the configuration of the process) has placed on the allocation behavior. The process may be killed but then the sysadmin or developer can investigate the situation. The solution is similar to what we do when running out of hugepages. This patch adds a check before we kill processes. At that point performance considerations do not matter much so we just scan the zonelist and reconstruct a list of nodes. If the list of nodes does not contain all online nodes then this is a constrained allocation and we should kill the current process.

* | [PATCH] HPET: handle multiple ACPI EXTENDED_IRQ resourcesBjorn Helgaas2006-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the _CRS for a single HPET contains multiple EXTENDED_IRQ resources, we overwrote hdp->hd_nirqs every time we found one. So the driver worked when all the IRQs were described in a single EXTENDED_IRQ resource, but failed when multiple resources were used. (Strictly speaking, I think the latter is actually more correct, but both styles have been used.) Someday we should remove all the ACPI stuff from hpet.c and use PNP driver registration instead. But currently PNP_MAX_IRQ is 2, and HPETs often have more IRQs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix hole where tty structure can be released when reference count is non zero. Existing code can sleep without tty_sem protection between deciding to release the tty structure (setting local variables tty_closing and otty_closing) and setting TTY_CLOSING to prevent further opens. An open can occur during this interval causing release_dev() to free the tty structure while it is still referenced.
