IRQF_DISABLED is not needed because the first thing that ide_intr()
(IDE IRQ handler) does is calling spin_lock_irqsave() which disables
local IRQs (IRQ unmasking is later handled by drive->unmask).
kernel/irq/handle.c:
irqreturn_t handle_IRQ_event(unsigned int irq, struct irqaction *action)
...
if (!(action->flags & IRQF_DISABLED))
local_irq_enable_in_hardirq();
do {
ret = action->handler(irq, action->dev_id);
if (ret == IRQ_HANDLED)
status |= action->flags;
retval |= ret;
action = action->next;
} while (action);
...
drivers/ide/ide-io.c:
irqreturn_t ide_intr (int irq, void *dev_id)
...
spin_lock_irqsave(&ide_lock, flags);
...
spin_unlock(&ide_lock);
...
if (drive->unmask)
local_irq_enable_in_hardirq();

* pmac_ide_init_hwif_ports() can be called by ide_init_hwif_ports()
(through ppc_ide_md.ide_init_hwif hook) for non IDE PMAC interfaces.
If this is the case the hw->io_ports[] should be already setup by
ide_init_hwif_ports()->ide_std_init_ports() so remove redundant code
from pmac_ide_init_hwif_ports().
As side-effect this change fixes ctl_addr == 0 special handling in
ide_init_hwif_ports().
* Fix misleading comment while at it.

Based on the earlier work by Tejun Heo.
* Move setting IDE_TFLAG_LBA48 taskfile flag from do_rw_taskfile()
function to the callers.
* Add IDE_TFLAG_FLAGGED taskfile flag for flagged taskfiles coming
from ide_taskfile_ioctl(). Check it instead of ->tf_out_flags.all.
* Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load
IDE data register in ide_tf_load().
* Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load
particular IDE taskfile registers in ide_tf_load().
* Update do_rw_taskfile() and ide_tf_load() users to set respective
IDE_TFLAG_OUT_* taksfile flags.
* Add task_dma_ok() helper.
* Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load().
* Use do_rw_taskfile() in flagged_taskfile().
* Remove no longer needed 'tf_out_flags' field from ide_task_t.
There should be no functionality changes caused by this patch.

Load IDE_SECTOR_REG after IDE_FEATURE_REG and IDE_NSECTOR_REG when using CHS.
This patch is basically a preparation for the next one which converts
__ide_do_rw_disk() to use struct ide_taskfile.
It shouldn't affect anything (just a usual paranoia to separate changes
which change the way in which hardware is accessed from code cleanups).

Currently it's possible to ide-cd to set an incorrect blocksize by
reading garbage if the drive is dead:
ide_cd_probe()
-> cdrom_read_toc()
-> cdrom_read_capacity()
-> cdrom_queue_packet_command()
-> ide_do_drive_cmd()
-> ide_do_request()
-> start_request()
on start_request():
/* bail early if we've exceeded max_failures */
if (drive->max_failures && (drive->failures > drive->max_failures)) {
goto kill_rq;
}
(...)
kill_rq:
ide_kill_rq(drive, rq);
return ide_stopped;
ide_kill_rq() and the next calls won't set REQ_FAILED on rq->cmd_flags and thus
cdrom_queue_packet_command() won't return an error. then:
stat = cdrom_queue_packet_command(drive, &req);
if (stat == 0) {
*capacity = 1 + be32_to_cpu(capbuf.lba);
*sectors_per_frame =
be32_to_cpu(capbuf.blocklen) >> SECTOR_BITS;
}
cdrom_read_capacity() ends believing capbuf is valid but in fact it's just
uninitialized data. back to cdrom_read_toc():
/* Try to get the total cdrom capacity and sector size. */
stat = cdrom_read_capacity(drive, &toc->capacity, §ors_per_frame,
sense);
if (stat)
toc->capacity = 0x1fffff;
set_capacity(info->disk, toc->capacity * sectors_per_frame);
/* Save a private copy of te TOC capacity for error handling */
drive->probed_capacity = toc->capacity * sectors_per_frame;
blk_queue_hardsect_size(drive->queue,
sectors_per_frame << SECTOR_BITS);
that will set drive->queue->hardsect_size to be the random value.
hardsect_size is used to calculate inode->i_blkbits. later on, on a read
path:
void create_empty_buffers(struct page *page,
unsigned long blocksize, unsigned long b_state)
{
struct buffer_head *bh, *head, *tail;
head = alloc_page_buffers(page, blocksize, 1);
bh = head;
do {
bh->b_state |= b_state;
tail = bh;
bh = bh->b_this_page;
} while (bh);
tail->b_this_page = head;
alloc_page_buffers() will return NULL if blocksize > 4096. blocksize is
calculed based on inode->i_blkbits. that will trigger a null
dereference on create_empty_buffers().

- align the code hooking the IDE DMA methods in init_hwif_trm290()...

ACPI _PS3 cause S4 breaks in the second attempt. The system has a _PS3
method for IDE, which will call into SMM mode. Currently we haven't clue
why just the second attempt fails, as it's totally in BIOS code, so
blacklist the system so far for 2.6.24.
A possible suspect is ACPI NVS isn't save/restore, we will revisit the
bug after linux does ACPI NVS save/restore.

After looking into the HPT370 manual (now that I have it) and re-checking all
the timing tables, here's what I have discovered:
- at 33 MHz clock, PIO mode 0 timings turned to be overclocked, and all other
PIO modes underclocked;
- at 50 MHz clock, PIO modes 0 to 2 turned to be overclocked;
- at 66 MHz clock, PIO mode 0 was overclocked too.
Finally, the taskfile timing (matching PIO mode 0) turned to be overclocked at
all clock frequencies (and in all manuals)...
The new timings have been tested on HPT370 chip (at 33 MHz PCI clock) and on
HPT371N chip (at both 50 and 66 MHz DPLL clock).

post_transform_command() call in cdrom_newpc_intr() has no effect because
it is done after the request has already been fully completed (rq->bio and
rq->data are always NULL). It was verified to be true regardless whether
INQUIRY command is using DMA or PIO to transfer data (by using modified
Tejun Heo's test-shortsg.c utility and adding a few printk()-s to ide-cd).
This was uncovered thanks to the "blk_end_request: full I/O completion
handler (take 3)" patch series from Kiyoshi Ueda.

* ide_xfer_verbose() fixups:
- beautify returned mode names
- fix PIO5 reporting
- make it return 'const char *'
* Change printk() level from KERN_DEBUG to KERN_INFO in ide_find_dma_mode().
* Add ide_id_dma_bug() helper based on ide_dma_verbose() to check for invalid
DMA info in identify block.
* Use ide_id_dma_bug() in ide_tune_dma() and ide_driveid_update().
As a result DMA won't be tuned or will be disabled after tuning if device
reports inconsistent info about enabled DMA mode (ide_dma_verbose() does the
same checks while the IDE device is probed by ide-{cd,disk} device driver).
* Remove no longer needed ide_dma_verbose().
This patch should fix the following problem with out-of-sync IDE messages
reported by Nick Warne:
hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd:
skipping word 93 validity check
, UDMA(66)
and later debugged by Mark Lord to be caused by:
ide_dma_verbose()
printk( ... "2048kB Cache");
eighty_ninty_three()
printk(KERN_DEBUG "%s: skipping word 93 validity check\n");
ide_dma_verbose()
printk(", UDMA(66)"
Please note that as a result ide-{cd,disk} device drivers won't report the
DMA speed used but this is intended since now DMA mode being used is always
reported by IDE core code.
v2:
* fixes suggested by Randy:
- use KERN_CONT for printk()-s in ide-{cd,disk}.c
- don't remove argument name from ide_xfer_verbose() declaration
v3:
* Remove incorrect check for (id->field_valid & 1) from ide_id_dma_bug()
(spotted by Sergei).
* "XFER SLOW" -> "PIO SLOW" in ide_xfer_verbose() (suggested by Sergei).
* Fix ide_find_dma_mode() to report the correct mode ('mode' after being
limited by 'req_mode').
