* VFS: Add GPL_EXPORTED function vfs_kern_mount()Trond Myklebust2006-06-09
| | | | | | | | | | | | do_kern_mount() does not allow the kernel to use private mount interfaces without exposing the same interfaces to userland. The problem is that the filesystem is referenced by name, thus meaning that it and its mount interface must be registered in the global filesystem list. vfs_kern_mount() passes the struct file_system_type as an explicit parameter in order to overcome this limitation.

* NFS: Flesh out nfs_invalidate_page()Trond Myklebust2006-06-09

* NFS: Separate metadata and page cache revalidation mechanismsTrond Myklebust2006-06-09
| | | | | | | | | | Separate out the function of revalidating the inode metadata, and revalidating the mapping. The former may be called by lookup(), and only really needs to check that permissions, ctime, etc haven't changed whereas the latter needs only done when we want to read data from the page cache, and may need to sync and then invalidate the mapping.

| | | | | | | | | | | | | | From: Martin Schwidefsky <schwidefsky@de.ibm.com> __futex_atomic_op needs to do an atomic operation in the user address space, not the kernel address space.

* [PATCH] elevator switching raceJens Axboe2006-06-08
| | | | | | | | | | | | | | | | | | | | There's a race between shutting down one io scheduler and firing up the next, in which a new io could enter and cause the io scheduler to be invoked with bad or NULL data. To fix this, we need to maintain the queue lock for a bit longer. Unfortunately we cannot do that, since the elevator init requires to be run without the lock held. This isn't easily fixable, without also changing the mempool API. So split the initialization into two parts, and alloc-init operation and an attach operation. Then we can preallocate the io scheduler and related structures, and run the attach inside the lock after we detach the old one. This patch has survived 30 minutes of 1 second io scheduler switching with a very busy io load. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Worse, on some platforms we route interrupts to secondary CPUs using cpu_possible_map which is still populated properly. As a result, these interrupts go nowhere so the machines like DP264 aren't able to boot even with a primary CPU. Fixed basically by s/cpu_present_mask/cpu_present_map/.

Stepping A1 of the ixp2350, which has a PRODUCT_ID of 0x401, has '02' in the lower byte of processor_id, while A2, with a PRODUCT_ID of 0x402, has '04' in the lower byte of processor_id. So, to check for >= A2, we really need to check the lower byte of processor_id against >= 4.

Thus, the both pages might not really be made global for the CPU (since it AND's the G-bit of the odd / even PTEs together to decide whether they're global or not). Thus, if only a single page is allocated via vmalloc() or ioremap(), it's not really global for CPU (and it must be, since this is kernel mapping), and thus its ASID is compared against the current process' one -- so, we'll get into trouble sooner or later... Also, pte_none() will fail on global pages because _PAGE_GLOBAL bit is set in both pte_low and pte_high, and pte_val() will return u64 value consisting of those fields concateneted.
