This patch includes feedback from Andrew and Christoph. Thanks for taking time to review. Use of empty_zero_page was eliminated to fix compilation for architectures that don't have it. This patch removes setting pages up-to-date in ext2_get_xip_page and all bug checks to verify that the page is indeed up to date. Setting the page state on mapping to userland is bogus. None of the code patchs involved with these pages in mm cares about the page state. still on my ToDo list: identify a place outside second extended where __inode_direct_access should reside Signed-off-by:

- In CX88 code, some cards needs to have audio reprogramed after changing video channel; - Tuner autodetection code seems not to work on some cards. Now, no_autodetect insmod option allows disabling autodetection code; - Minor fixes in tea5767 to reduce integer trunc; - There are some new Pixelview Ultra Pro cards that doesn't use TEA5767 for radio. As autodetection is capable of checking for tea, radio tuners and addresses removed. - CX88 version number incremented. Signed-off-by:

This patch makes the command: make ARCH=um SUBARCH=i386 work on x86_64 hosts (with support for building 32-bit binaries). This is especially needed since 64-bit UMLs don't support 32-bit emulation for guest binaries, currently. This has been tested in all possible cases and works. Only exception is that I've built but not tested a 64-bit binary, because I hadn't a 64-bit filesystem available. Signed-off-by:

The pcap support was not working because of some linking problems (expressing the construct in Kbuild was a bit difficult) and because there was no user request. Now that this has come back, here's the support. This has been tested and works on both 32 and 64-bit hosts, even when "cross-"building 32-bit binaries. Signed-off-by:

1) Cleanup an ugly hyper-nested code in Makefile (now only the arith. expression is passed through the host bash). 2) Fix a problem with GCC 2.95: according to a report from Raphael Bossek, .remap_data : { arch/um/sys-SUBARCH/unmap_fin.o (.data .bss) } is expanded into: .remap_data : { arch/um/sys-i386 /unmap_fin.o (.data .bss) } (because I didn't use ## to join the two tokens), thus stopping linking. Pass the whole path from the Makefile as a simple and nice fix. Signed-off-by: -

*) Reorganize the two cases of sys_modify_ldt to share all the reasonably common code. *) Avoid memory allocation when unneeded (i.e. when we are writing and the passed buffer size is known), thus not returning ENOMEM (which isn't allowed for this syscall, even if there is no strict "specification"). *) Add copy_{from,to}_user to modify_ldt for TT mode.

A big bug has been diagnosed on hosts running the SKAS patch and built with CONFIG_REGPARM, due to some missing prevent_tail_call(). On these hosts, this workaround is needed to avoid triggering that bug, because "to" is kept by GCC only in EBX, which is corrupted at the return of mmap2(). Since to trigger this bug int 0x80 must be used when doing the call, it rarely manifests itself, so I'd prefer to get this merged to workaround that host bug, since it should cause no functional change. Still, you might prefer to drop it, I'll leave this to you. Signed-off-by:

Russell King <rmk+lkml@arm.linux.org.uk> This construct is refused by GCC 4, so here's the (corrected) fix. Thanks to Russell for noticing a stupid mistake I did when first sending this. As he noted, the code is largely suboptimal however it currently works, and will be fixed shortly. Just read the access_ok check on fp which is NULL, or the pointer arithmetic below which should be done with a cast to void*: frame = (struct rt_sigframe __user *) round_down(stack_top - sizeof(struct rt_sigframe), 16) - 8; The code shows clearly that has been taken from arch/x86_64/kernel/signal.c:setup_rt_frame(), maybe in a bit of a hurry.

Add special case for the POSIX_FADV_DONTNEED and POSIX_FADV_NOREUSE hint values for s390-64. The user space values in the s390-64 glibc headers for these two defines have always been 6 and 7 instead of 4 and 5. All 64 bit applications therefore use the "wrong" values. To get these applications working without recompiling the kernel needs to accept the "wrong" values. Since the values for s390-31 are 4 and 5 the compat wrapper for fadvise64 and fadvise64_64 need to rewrite the values for 31 bit system calls. Signed-off-by:

Fix for a race condition when a task gets preempted by another task while executing the destroy_context(...) in a FEW_CONTEXTS environment. mm->context == NO_CONTEXT but the context_map may indicate all contexts are in use.

Something has changed in the core kernel such that we now get concurrent inode write outs, one e.g via pdflush and one via sys_sync or whatever. This causes a nasty deadlock in ntfs. The only clean solution unfortunately requires a minor vfs api extension. First the deadlock analysis: Prerequisive knowledge: NTFS has a file $MFT (inode 0) loaded at mount time. The NTFS driver uses the page cache for storing the file contents as usual. More interestingly this file contains the table of on-disk inodes as a sequence of MFT_RECORDs. Thus NTFS driver accesses the on-disk inodes by accessing the MFT_RECORDs in the page cache pages of the loaded inode $MFT. The situation: VFS inode X on a mounted ntfs volume is dirty. For same inode X, the ntfs_inode is dirty and thus corresponding on-disk inode, which is as explained above in a dirty PAGE_CACHE_PAGE belonging to the table of inodes ($MFT, inode 0). What happens: Process 1: sys_sync()/umount()/whatever... calls __sync_single_inode() for $MFT -> do_writepages() -> write_page for the dirty page containing the on-disk inode X, the page is now locked -> ntfs_write_mst_block() which clears PageUptodate() on the page to prevent anyone else getting hold of it whilst it does the write out (this is necessary as the on-disk inode needs "fixups" applied before the write to disk which are removed again after the write and PageUptodate is then set again). It then analyses the page looking for dirty on-disk inodes and when it finds one it calls ntfs_may_write_mft_record() to see if it is safe to write this on-disk inode. This then calls ilookup5() to check if the corresponding VFS inode is in icache(). This in turn calls ifind() which waits on the inode lock via wait_on_inode whilst holding the global inode_lock. Process 2: pdflush results in a call to __sync_single_inode for the same VFS inode X on the ntfs volume. This locks the inode (I_LOCK) then calls write-inode -> ntfs_write_inode -> map_mft_record() -> read_cache_page() of the page (in page cache of table of inodes $MFT, inode 0) containing the on-disk inode. This page has PageUptodate() clear because of Process 1 (see above) so read_cache_page() blocks when tries to take the page lock for the page so it can call ntfs_read_page(). Thus Process 1 is holding the page lock on the page containing the on-disk inode X and it is waiting on the inode X to be unlocked in ifind() so it can write the page out and then unlock the page. And Process 2 is holding the inode lock on inode X and is waiting for the page to be unlocked so it can call ntfs_readpage() or discover that Process 1 set PageUptodate() again and use the page. Thus we have a deadlock due to ifind() waiting on the inode lock. The only sensible solution: NTFS does not care whether the VFS inode is locked or not when it calls ilookup5() (it doesn't use the VFS inode at all, it just uses it to find the corresponding ntfs_inode which is of course attached to the VFS inode (both are one single struct); and it uses the ntfs_inode which is subject to its own locking so I_LOCK is irrelevant) hence we want a modified ilookup5_nowait() which is the same as ilookup5() but it does not wait on the inode lock. Without such functionality I would have to keep my own ntfs_inode cache in the NTFS driver just so I can find ntfs_inodes independent of their VFS inodes which would be slow, memory and cpu cycle wasting, and incredibly stupid given the icache already exists in the VFS. Below is a patch that does the ilookup5_nowait() implementation in fs/inode.c and exports it. ilookup5_nowait.diff: Introduce ilookup5_nowait() which is basically the same as ilookup5() but it does not wait on the inode's lock (i.e. it omits the wait_on_inode() done in ifind()). This is needed to avoid a nasty deadlock in NTFS. Signed-off-by:
