* omap2/3/4: Disable CONFIG_FB_OMAP in omap3_defconfigTony Lindgren2010-05-051-9/+1Star
| | | | | | | | | | | | | Looks like CONFIG_FB_OMAP prevents somehow mounting root on MMC at least on zoom3 for multi-omap. Disable CONFIG_FB until the omap FB code is fixed. This allows booting omap3_defconfig on various omaps. Tested on 2420-n8x0, 3430-n900, 3630-zoom3 and 4430-blaze. Note that n8x0 still has issues with starting user space because of TLS and VFP.

* omap2/3/4: Make omap3_defconfig usable on Nokia boardsTony Lindgren2010-05-041-2/+2
| | | | | | | | | | | | | | | | | The bootloader on Nokia boards does not support updating the kernel cmdline. For the other boards, the bootloader provided cmdline will be used instead. To mount root on n8x0, compile in also the MMC_OMAP. It seems that the best way to mount root with the new kernels on Nokia boards is to mount root on mmcblk0p2. Note that n8x0 current has several issues booting with omap3_defconfig: The bootloader has a 2MB limit for loading kernels, so you may want to use kexec. Also ARMv6 does not currently work with ARMv7 for VFP and TLS. Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | We cannot use the omap34xx_sram_init(). It needs to be implemented for omap4.

* omap2/3: Fix DEBUG_LL for omap zoom2/3Tony Lindgren2010-05-046-8/+17
| | | | | | | | | | | | | | | | | Zoom2 and 3 have UARTs only on the external debug board. GPMC needs to be mapped early to use it for DEBUG_LL. Additionally, 0xfb000000 overlaps with other areas, so use 0xfa400000 for the virtual address instead. Note that with the pending serial.c patches you need to set console=ttyS0,115200n8 as it will be the only UART mapped. To use DEBUG_LL, you need to pass also earlyprintk in cmdline.

* omap: Use a memory address for storing the debug port info instead of UART1 ↵Tony Lindgren2010-05-044-47/+43Star
| | | | | | | | | | | | | | | | | | | | | | scratchpad This removes the dependency to the UART1 being available for storing the debug configuration in uncompress.h. This will simplify the DEBUG_LL UART configuration for boards that may not have UART1, or have an external UART as it requires only one mapping for DEBUG_LL. The patch has a few limitations. Basically now we're assuming that the kernel uncompress code won't overlap with OMAP_UART_INFO. We also assume the printascii is called at least once before paging_init in order for addruart to have a chance to read the UART setup from OMAP_UART_INFO. As suggested by Cyril Chemparathy <cyril@ti.com>, Vikram Pandita <vikram.pandita@ti.com> and Kevin Hilman <khilman@deeprootsystems.com>. Based on an earlier patch posted for Davinci by Cyril Chemparathy <cyril@ti.com>. Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | Otherwise we'll get an error about get_irqnr_and_base being defined twice. Add an entry for omap4, and use ARCH_OMAP3 for omap3 instead of ARCH_OMAP3430. Also fix the check for omap1 to use ARCH_OMAP2PLUS to avoid having to add ARCH_OMAP4 separately there. Signed-off-by: Tony Lindgren <tony@atomide.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | On low memory boxes or those with highmem, kernel can OOM before the background reclaims inodes via xfssyncd. Add a shrinker to run inode reclaim so that it inode reclaim is expedited when memory is low. This is more complex than it needs to be because the VM folk don't want a context added to the shrinker infrastructure. Hence we need to add a global list of XFS mount structures so the shrinker can traverse them. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

Unfortunately the old method now caps the topology to work around issues with legacy operating systems. For Linux to get the correct topology we need to use the new form 1 affinity information. We set the form 1 field in the client architecture, and if we see "1" in the ibm,associativity-form property firmware supports form 1 affinity and we should look at the first field in the ibm,associativity-reference-points array.

| * | | | nfs: fix memory leak in nfs_get_sb with CONFIG_NFS_V4Xiaotian Feng2010-04-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With CONFIG_NFS_V4 and data version 4, nfs_get_sb will allocate memory for export_path in nfs4_validate_text_mount_data, so we need to free it then. This is addressed in following kmemleak report: unreferenced object 0xffff88016bf48a50 (size 16): comm "mount.nfs", pid 22567, jiffies 4651574704 (age 175471.200s) hex dump (first 16 bytes): 2f 6f 70 74 2f 77 6f 72 6b 00 6b 6b 6b 6b 6b a5 /opt/work.kkkkk. backtrace: [<ffffffff814b34f9>] kmemleak_alloc+0x60/0xa7 [<ffffffff81102c76>] kmemleak_alloc_recursive.clone.5+0x1b/0x1d [<ffffffff811046b3>] __kmalloc_track_caller+0x18f/0x1b7 [<ffffffff810e1b08>] kstrndup+0x37/0x54 [<ffffffffa0336971>] nfs_parse_devname+0x152/0x204 [nfs] [<ffffffffa0336af3>] nfs4_validate_text_mount_data+0xd0/0xdc [nfs] [<ffffffffa0338deb>] nfs_get_sb+0x325/0x736 [nfs] [<ffffffff81113671>] vfs_kern_mount+0xbd/0x17c [<ffffffff81113798>] do_kern_mount+0x4d/0xed [<ffffffff81129a87>] do_mount+0x787/0x7fe [<ffffffff81129b86>] sys_mount+0x88/0xc2 [<ffffffff81009b42>] system_call_fastpath+0x16/0x1b Signed-off-by: Xiaotian Feng <dfeng@redhat.com> Cc: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: Chuck Lever <chuck.lever@oracle.com> Cc: Benny Halevy <bhalevy@panasas.com> Cc: Al Viro <viro@ZenIV.linux.org.uk> Cc: Andy Adamson <andros@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original code passed an ERR_PTR() to rpc_put_task() and instead of returning zero on success it returned -ENOMEM.

| * | | | NFS: Ensure that nfs_wb_page() waits for Pg_writeback to clearTrond Myklebust2010-04-281-15/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Neil Brown reports that he is seeing the BUG_ON(ret == 0) trigger in nfs_page_async_flush. According to the trace in https://bugzilla.novell.com/show_bug.cgi?id=599628 the problem appears to be due to nfs_wb_page() not waiting for the PG_writeback flag to clear. There is a ditto problem in nfs_wb_page_cancel() Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| * | | | NFS: Fix an unstable write data integrity raceTrond Myklebust2010-04-222-4/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2c61be0a9478258f77b66208a0c4b1f5f8161c3c (NFS: Ensure that the WRITE and COMMIT RPC calls are always uninterruptible) exposed a race on file close. In order to ensure correct close-to-open behaviour, we want to wait for all outstanding background commit operations to complete. This patch adds an inode flag that indicates if a commit operation is under way, and provides a mechanism to allow ->write_inode() to wait for its completion if this is a data integrity flush.

| * | | | nfs: testing for null instead of ERR_PTR()Dan Carpenter2010-04-221-1/+1

| * | | | NFS: rsize and wsize settings ignored on v4 mountsChuck Lever2010-04-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFSv4 mounts ignore the rsize and wsize mount options, and always use the default transfer size for both. This seems to be because all NFSv4 mounts are now cloned, and the cloning logic doesn't copy the rsize and wsize settings from the parent nfs_server. I tested Fedora's 2.6.32.11-99 and it seems to have this problem as well, so I'm guessing that .33, .32, and perhaps older kernels have this issue as well.
