* Serial: EG20T: add PCH_UART driverTomoya MORINAGA2010-11-303-0/+1459
| | | | | | | | | | | | | | UART driver of Intel EG20T(Topcliff) PCH Intel EG20T PCH is the platform controller hub that is going to be used in Intel's general embedded platform. All IO peripherals in Intel EG20T PCH are actually devices sitting on AMBA bus. Intel EG20T PCH has UART I/F. Using this I/F, it is able to access system devices connected to UART.

| | | | | | | | | | | | | | | It allows users to see what consoles are currently known to the system and with what flags. It is based on Werner's patch, the part about traversing fds was removed, the code was moved to kernel/printk.c, where consoles are handled and it makes more sense to me.

Unfortunately, this no longer works, because in commit dd3932eddf (block: remove BLKDEV_IFL_WAIT), sb_issue_discard() only presents a synchronous interface, and there are times when we call ext4_free_blocks() when we are are holding a spinlock, or are otherwise in an atomic context. For now, I've removed the call to sb_issue_discard() to prevent a deadlock or (if spinlock debugging is enabled) failures like this: BUG: scheduling while atomic: rc.sysinit/1376/0x00000002 Pid: 1376, comm: rc.sysinit Not tainted 2.6.36-ARCH #1 Call Trace: [<ffffffff810397ce>] __schedule_bug+0x5e/0x70 [<ffffffff81403110>] schedule+0x950/0xa70 [<ffffffff81060bad>] ? insert_work+0x7d/0x90 [<ffffffff81060fbd>] ? queue_work_on+0x1d/0x30 [<ffffffff81061127>] ? queue_work+0x37/0x60 [<ffffffff8140377d>] schedule_timeout+0x21d/0x360 [<ffffffff812031c3>] ? generic_make_request+0x2c3/0x540 [<ffffffff81402680>] wait_for_common+0xc0/0x150 [<ffffffff81041490>] ? default_wake_function+0x0/0x10 [<ffffffff812034bc>] ? submit_bio+0x7c/0x100 [<ffffffff810680a0>] ? wake_bit_function+0x0/0x40 [<ffffffff814027b8>] wait_for_completion+0x18/0x20 [<ffffffff8120a969>] blkdev_issue_discard+0x1b9/0x210 [<ffffffff811ba03e>] ext4_free_blocks+0x68e/0xb60 [<ffffffff811b1650>] ? __ext4_handle_dirty_metadata+0x110/0x120 [<ffffffff811b098c>] ext4_ext_truncate+0x8cc/0xa70 [<ffffffff810d713e>] ? pagevec_lookup+0x1e/0x30 [<ffffffff81191618>] ext4_truncate+0x178/0x5d0 [<ffffffff810eacbb>] ? unmap_mapping_range+0xab/0x280 [<ffffffff810d8976>] vmtruncate+0x56/0x70 [<ffffffff811925cb>] ext4_setattr+0x14b/0x460 [<ffffffff811319e4>] notify_change+0x194/0x380 [<ffffffff81117f80>] do_truncate+0x60/0x90 [<ffffffff811e08fa>] ? security_inode_permission+0x1a/0x20 [<ffffffff811eaec1>] ? tomoyo_path_truncate+0x11/0x20 [<ffffffff81127539>] do_last+0x5d9/0x770 [<ffffffff811278bd>] do_filp_open+0x1ed/0x680 [<ffffffff8140644f>] ? page_fault+0x1f/0x30 [<ffffffff81132bfc>] ? alloc_fd+0xec/0x140 [<ffffffff81118db1>] do_sys_open+0x61/0x120 [<ffffffff81118e8b>] sys_open+0x1b/0x20 [<ffffffff81002e6b>] system_call_fastpath+0x16/0x1b https://bugzilla.kernel.org/show_bug.cgi?id=22302 Reported-by: Mathias Burén <mathias.buren@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: jiayingz@google.com

In ordered mode, we need to make sure the data pages are written just in case we crash before the rename (or unlink) is committed. If the inode is being freed then when we try to igrab the inode, we end up tripping the BUG_ON at fs/ext4/page-io.c:146. To solve this problem, we need to keep track of the number of io callbacks which are pending, and avoid destroying the inode until they have all been completed. That way we don't have to bump the inode count to keep the inode from being destroyed; an approach which doesn't work because the count could have already been dropped down to zero before the inode writeback has started (at which point we're not allowed to bump the count back up to 1, since it's already started getting freed). Thanks to Dave Chinner for suggesting this approach, which is also used by XFS. kernel BUG at /scratch_space/linux-2.6/fs/ext4/page-io.c:146!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the config bit are presently duplicated between the platforms, which will gradually cleaned up through centralization. For the moment we expose some new INTC features through drivers/sh/Kconfig that the ARM platforms presently don't enable, so make it generally available.
