2011-03-15[net/9p] Small non-IO PDUs for zero-copy supporting transports.Venkateswararao Jujjuri (JV)2-7/+18
If a transport prefers payload to be sent separate from the PDU (P9_TRANS_PREF_PAYLOAD_SEP), there is no need to allocate msize PDU buffers(struct p9_fcall). This patch allocates only upto 4k buffers for this kind of transports and there won't be any change to the legacy transports. Hence, this patch on top of zero copy changes allows user to specify higher msizes through the mount option without hogging the kernel heap.

2011-03-15[net/9p] Handle Zero Copy TREAD/RERROR case in !dotl case.Venkateswararao Jujjuri (JV)1-23/+41
This takes care of copying out error buffers from user buffer payloads when we are using zero copy. This happens because the only payload buffer the server has to respond to the request is the user buffer given for the zero copy read. Because we only use zerocopy when the amount of data to transfer is greater than a certain size (currently 4K) and error strings are limited to ERRMAX (currently 128) we don't need to worry about there being sufficient space for the error to fit in the payload.

This patch adds preferences field to the p9_trans_module.

2011-03-15[net/9p] Preparation and helper functions for zero copyVenkateswararao Jujjuri (JV)5-0/+139
This patch prepares p9_fcall structure for zero copy. Added fields send the payload buffer information to the transport layer. In addition it adds a 'private' field for the transport layer to store mapped/pinned page information so that it can be freed/unpinned during req_done. This patch also creates trans_common.[ch] to house helper functions. It adds the following helper functions. p9_release_req_pages - Release pages after the transaction. p9_nr_pages - Return number of pages needed to accomodate the payload. payload_gup - Translates user buffer into kernel pages.

2011-03-15[fs/9P] Add posixacl mount optionVenkateswararao Jujjuri (JV)4-12/+31
The mount option access=client is overloaded as it assumes acl too. Adding posixacl option to enable POSIX ACLs makes it explicit and clear. Also it is convenient in the future to add other types of acls like richacls. Ideally, the access mode 'client' should be just like V9FS_ACCESS_USER except it underscores the location of access check. Traditional 9P protocol lets the server perform access checks but with this mode, all the access checks will be performed on the client itself. Server just follows the client's directive.

2011-03-14oom: oom_kill_process: fix the child_points logicOleg Nesterov1-3/+8
oom_kill_process() starts with victim_points == 0. This means that (most likely) any child has more points and can be killed erroneously. Also, "children has a different mm" doesn't match the reality, we should check child->mm != t->mm. This check is not exactly correct if t->mm == NULL but this doesn't really matter, oom_kill_task() will kill them anyway. Note: "Kill all processes sharing p->mm" in oom_kill_task() is wrong too.

2011-03-14MIPS: Alchemy: Fix reset for MTX-1 and XXS1500Florian Fainelli2-4/+4
Since commit 32fd6901 (MIPS: Alchemy: get rid of common/reset.c) Alchemy-based boards use their own reset function. For MTX-1 and XXS1500, the reset function pokes at the BCSR.SYSTEM_RESET register, but this does not work. According to Bruno Randolf, this was not tested when written. Previously, the generic au1000_restart() routine called the board specific reset function, which for MTX-1 and XXS1500 did not work, but finally made a jump to the reset vector, which really triggers a system restart. Fix reboot for both targets by jumping to the reset vector.
