ARM: OMAP: MPUIO wake updates
GPIO and MPUIO wake updates:
- Hook MPUIOs into the irq wakeup framework too. This uses a platform
device to update irq enables during system sleep states, instead of
a sys_device, since the latter is no longer needed for such things.
- Also forward enable/disable irq wake requests to the relevant GPIO
controller, so the top level IRQ dispatcher can (eventually) handle
these wakeup events automatically if more than one GPIO pin needs to
be a wakeup event source.
- Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such
read-only data under the spinlock.
This assumes (maybe wrongly?) that only 16xx can do GPIO wakeup; without
a 15xx I can't test such stuff.
Also this expects the top level IRQ dispatcher to properly handle requests
to enable/disable irq wake, which is currently known to be wrong: omap1
saves the flags but ignores them, omap2 doesn't even save it. (Wakeup
events are, wrongly, hardwired in the relevant mach-omapX/pm.c file ...)
So MPUIO irqs won't yet trigger system wakeup.

In addition to H4 support, one key improvement is supporting not just
the "old" ARM debug LED API (with timer and idle LEDs, plus four that

This fixes a regression caused by commit:
2dc611de5a3fd955cd0298c50691d4c05046db97
The sense buffer code in scsi_send_eh_cmnd was changed to use
alloc_page() and a scatter list, but the sense data copy was not
updated to match so what we actually get in the sense buffer is total
grabage starting with the kernel address of the struct page we got.
Basically the stack frame of scsi_send_eh_cmd() is what ends up
in the sense buffer.
Depending upon how pointers look on a given platform, you can
end up getting sr_ioctl.c errors when you mount a cdrom. If
the CDROM gives a check condition for GPCMD_GET_CONFIGURATION issued
by drivers/cdrom/cdrom.c:cdrom_mmc_profile(), sr_ioctl will
spit out this error message in sr_do_ioctl() with the way pointers
are on sparc64:
default:
printk(KERN_ERR "%s: CDROM (ioctl) error, command: ", cd->cdi.name);
__scsi_print_command(cgc->cmd);
scsi_print_sense_hdr("sr", &sshdr);
err = -EIO;
This is the error Tom Callaway reported in:
http://marc.info/?l=linux-sparc&m=

__copy_to_user_inatomic() on such systems calls functions which might

The original check for WP-works-ok was in access_ok(), but got moved

Return the number of bytes to copy in the case where we are in an atomic
region, so the non atomic code pathes in file_read_actor() and

This could be optimized to avoid the kmap_atomicby moving the check for

Dmitry points out
"When we block_prepare_write() failed while ext3_prepare_write() we jump to
"failure" label and call ext3_prepare_failure() witch search last mapped bh
and invoke commit_write untill it. This is wrong!! because some bh from
begining to the last mapped bh may be not uptodate. As a result we commit to
disk not uptodate page content witch contains garbage from previous usage."
and
"Unexpected file size increasing."
Call trace the same as it was in first issue but result is different.
For example we have file with i_size is zero. we want write two blocks ,
but fs has only one free block.
->ext3_prepare_write(...from == 0, to == 2048)
retry:
->block_prepare_write() == -ENOSPC# we failed but allocated one block here.
->ext3_prepare_failure()
->commit_write( from == 0, to == 1024) # after this i_size becomes 1024 :)
if (ret == -ENOSPC && ext3_should_retry_alloc(inode->i_sb, &retries))
goto retry;
Finally when all retries will be spended ext3_prepare_failure return
-ENOSPC, but i_size was increased and later block trimm procedures can't
help here.
We don't appear to have the horsepower to fix these issues, so let's put
things back the way they were for now.

[PATCH] uml: fix unreasonably long udelay
Currently we have a confused udelay implementation.
* __const_udelay does not accept usecs but xloops in i386 and x86_64
* our implementation requires usecs as arg
* it gets a xloops count when called by asm/arch/delay.h
Bugs related to this (extremely long shutdown times) where reported by some
x86_64 users, especially using Device Mapper.
To hit this bug, a compile-time constant time parameter must be passed -
that's why UML seems to work most times. Fix this with a simple udelay
implementation.
