* VT notifier fix for VT switchSamuel Thibault2008-03-041-0/+1
| | | | | | | | | | | | | | | VT notifier callbacks need to be aware of console switches. This is already partially done from console_callback(), but at that time fg_console, cursor positions, etc. are not yet updated and hence screen readers fetch the old values. This adds an update notify after all of the values are updated in redraw_screen(vc, 1).

The driver supports the Basic mode of Freescale MPC85xx DMA controller. The MPC85xx processors supported include MPC8540/60, MPC8555, MPC8548, MPC8641 and so on. The MPC83xx(MPC8349, MPC8360) are also supported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the #define READ_AHEAD 1024 from the driver and uses the block layer defaults, instead. We have found that under certain workloads the setting can cause a disk connected to the e200 controller to go offline. If the disk hiccups the link may try to downshift but the controller is never notified that the link successfully completed the renegotiation. We've also found that performance using the block layer default of 32 pages was on par with the 1024 setting. We tried setting it to zero at one time based on info from our firmware guys but that killed performance. Turns out we were talking about 2 different read ahead settings.

| * | block: separate out padding from alignmentTejun Heo2008-03-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Block layer alignment was used for two different purposes - memory alignment and padding. This causes problems in lower layers because drivers which only require memory alignment ends up with adjusted rq->data_len. Separate out padding such that padding occurs iff driver explicitly requests it. Tomo: restorethe code to update bio in blk_rq_map_user introduced by the commit 40b01b9bbdf51ae543a04744283bf2d56c4a6afa according to padding alignment.

| * | block: restore the meaning of rq->data_len to the true data lengthFUJITA Tomonori2008-03-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of rq->data_len was changed to the length of an allocated buffer from the true data length. It breaks SG_IO friends and bsg. This patch restores the meaning of rq->data_len to the true data length and adds rq->extra_len to store an extended length (due to drain buffer and padding). This patch also removes the code to update bio in blk_rq_map_user introduced by the commit 40b01b9bbdf51ae543a04744283bf2d56c4a6afa. The commit adjusts bio according to memory alignment (queue_dma_alignment). However, memory alignment is NOT padding alignment. This adjustment also breaks SG_IO friends and bsg. Padding alignment needs to be fixed in a proper way (by a separate patch). Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <axboe@carl.home.kernel.dk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The maple bus driver that went into the kernel mainline in September 2007 contained some bugs which were revealed by the update of the kobj code for the current release series. Unfortunately those bugs also helped ensure maple devices were properly detected. This patch (against the current git) now ensures that devices are properly detected again. (A previous attempt to fix this by delaying initialisation only partially fixed this - as became apparent when the bus was fully loaded) Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
