ocfs2_extend_trans() might call journal_restart() which will commit dirty
buffers and then restart the transaction. This means that any buffers which
still need changes should be passed to journal_access() again. Some paths
during extend weren't doing this right.
Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
The nastiest cases of transaction extends are also the rarest. We can expose
them more quickly at the expense of performance by going straight to the
journal_restart() in ocfs2_extend_trans(). Wrap things in OCFS2_DEBUG_FS so
that we only do this when "expensive debugging" is turned on.

that prevented userspace from seing the "driver disk" lun in a san disk

The OHCI IRQ handler has an optimisation that avoids reading some
chip registers when the controller reports that the interrupt was
triggered *only* because completed requests were written into the
controller's "done list" and handed to the host.
This mechanism can't be used on some controllers. Among others, it
fails for the SA1111 and the AMCC 440EP PowerPC processor.
This patch removes the optimisation and makes the code clearer.

Correct hanging while disconnecting the USB device cable. Prevent a race
between vbus and UDP interrupts. This bug was tracked on at91sam9260ek
boards.
A usb resume interrupt was firing after the vbus interrupt : the IP was
then already stoped and not able to deal with it (no more clock). A simple
interrupt disabling is ok as the "end of bus reset" irq is non maskable and
ok to resume the USB device IP.

Host controller IRQs are supposed to be serviced with interrupts
disabled. This patch (as1026) adds an IRQF_DISABLED flag to all the
controller drivers that lack it. It also replaces the
spin_lock_irqsave() and spin_unlock_irqrestore() calls in uhci_irq()
with simple spin_lock() and spin_unlock().

When a device cannot handle the smallest previously limited transfer
size (64 blocks) without stalling, limit the device to the amount of
packets that fit in a platform native page.
The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever
used on a platform that has larger than 8K pages, you lose unless you
can convince the device firmware folks to fix the issue.

Git commit 3610cce87a (yeah my own :-/)
introduced a bug in regard to pud/pmd table entries.
If the address of the page table refered to by a pud/pmd value happens
to have zeroes in the lower 32 bits, pud_present and pmd_present return
false. The obvious effect is that this triggers the BUG_ON in exit_mmap
because some ptes will not get released on process end. Worse is that
the next fault for memory covered by that pud/pmd will allocate another
pmd/pte table and populate the pud/pmd entry. The old page table
entries hanging below this entry are lost!
The fix is simple, properly check against 0. The check is added for
pud_none/pmd_none as well even if these two functions work because
the invalid bit is in the lower 32 bits.

Bernard Pidoux reported these lockdep warnings:
[ INFO: possible irq lock inversion dependency detected ]
2.6.23.1 #1

fpac/4933 just changed the state of lock:
(slock-AF_AX25){--..}, at: [<d8be3312>] ax25_disconnect+0x46/0xaf
[ax25]
but this lock was taken by another, soft-irq-safe lock in the past:
(ax25_list_lock){-+..}
and interrupts could create inverse lock ordering between them.
[...]
[ INFO: inconsistent lock state ]
2.6.23.1 #1
---------------------------------
inconsistent {in-softirq-W} -> {softirq-on-W} usage.
ax25_call/4005 [HC0[0]:SC0[0]:HE1:SE1] takes:
(slock-AF_AX25){-+..}, at: [<d8b79312>] ax25_disconnect+0x46/0xaf [ax25]
[...]
This means slock-AF_AX25 could be taken both from softirq and process
context with softirqs enabled, so it's endangered itself, but also makes
ax25_list_lock vulnerable. It was not 100% verified if the real lockup
can happen, but this fix isn't very costly and looks safe anyway.
(It was tested by Bernard with 2.6.23.9 and 2.6.24-rc5 kernels.)
