* kbuild, deb-pkg: pass Debian maintainer script parameters to packaging hook ↵Frans Pop2009-06-09
| | | | | | | | | | | | | | | | | | | | scripts The Debian packaging scripts created by the deb-pkg target do not pass on the standard Debian maintainer script parameters to hook scripts, which means that those scripts cannot tell whether they are being called during e.g. install vs. upgrade, or removal vs. purge of the package. As there are several variantions in how hook scripts are called from kernel packages, we pass the parameters in the environment variable DEB_MAINT_PARAMS rather than as extra arguments. Bump version of builddep script to 1.3.

* async: Fix lack of boot-time console due to insufficient synchronizationLinus Torvalds2009-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Our async work synchronization was broken by "async: make sure independent async domains can't accidentally entangle" (commit d5a877e8dd409d8c702986d06485c374b705d340), because it would report the wrong lowest active async ID when there was both running and pending async work. This caused things like no being able to read the root filesystem, resulting in missing console devices and inability to run 'init', causing a boot-time panic. This fixes it by properly returning the lowest pending async ID: if there is any running async work, that will have a lower ID than any pending work, and we should _not_ look at the pending work list. There were alternative patches from Jaswinder and James, but this one also cleans up the code by removing the pointless 'ret' variable and the unnecesary testing for an empty list around 'for_each_entry()' (if the list is empty, the for_each_entry() thing just won't execute).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Outlining fixes the issue were on certain CPUs such as the R10000 family the delay loop would need an extra cycle if it overlaps a cacheline boundary. The rewrite also fixes build errors with GCC 4.4 which was changed in way incompatible with the kernel's inline assembly. Relying on pure C for computation of the delay value removes the need for explicit. The price we pay is a slight slowdown of the computation - to be fixed on another day.

So the dma_clear() method, the successor of dma_timeout(), shouldn't exist and the dma_lost_irq() method should be standard for PDC20246.

Applying this fix in non-secure mode results in the kernel failing to boot (or even do anything.) This fixes booting on some ARMv7 based platforms which otherwise silently fail.

However if the system was busy, or debugging was enabled, or a udelay(100) was inserted before the second SWITCH command in the core code, then the timing was so that the card started to work. With some unusual block sizes, the data FIFO status doesn't indicate a "empty" state right away when the data transfer is done. Queuing another data transfer in that condition results in a transfer timeout. The empty FIFO bit eventually get set by itself in less than 50 usecs when it is not set right away. So let's just poll for that bit before configuring the controller with a new data transfer. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Pierre Ossman <pierre@ossman.eu>

Since iget() et.al. will not accept I_FREEING (will wait to go away and restart), and since we'd better have serialization between new/free on fs data structures anyway, we can afford simply skipping I_FREEING et.al. in insert_inode_locked(). We do that from new_inode, so it won't race with free_inode in any interesting ways and it won't race with iget (of any origin; nfsd or in case of fs corruption a lookup) since both still will wait for I_LOCK.

Of these three, only ext2 and jfs's get_block() function pays attention to bh->b_size --- which is normally always the filesystem blocksize except when the get_block() function is called by either mpage_readpage(), mpage_readpages(), or the direct I/O routines in fs/direct_io.c. Unfortunately, nobh_truncate_page() does not initialize map_bh before calling the filesystem-supplied get_block() function. So ext2 and jfs will try to calculate the number of blocks to map by taking stack garbage and shifting it left by inode->i_blkbits. This should be *mostly* harmless (except the filesystem will do some unnneeded work) unless the stack garbage is less than filesystem's blocksize, in which case maxblocks will be zero, and the attempt to find out whether or not the filesystem has a hole at a given logical block will fail, and the page cache entry might not get zero'ed out. Also if the stack garbage in in map_bh->state happens to have the BH_Mapped bit set, there could be an attempt to call readpage() on a non-existent page, which could cause nobh_truncate_page() to return an error when it should not. Fix this by initializing map_bh->state and map_bh->size. Fortunately, it's probably fairly unlikely that ext2 and jfs users mount with nobh these days.
