2007-10-29fix abuses of ptrdiff_tAl Viro5-11/+13
Use of ptrdiff_t in places like - if (!access_ok(VERIFY_WRITE, u_tmp->rx_buf, u_tmp->len)) + if (!access_ok(VERIFY_WRITE, (u8 __user *) + (ptrdiff_t) u_tmp->rx_buf, + u_tmp->len)) is wrong; for one thing, it's a bad C (it's what uintptr_t is for; in general we are not even promised that ptrdiff_t is large enough to hold a pointer, just enough to hold a difference between two pointers within the same object). For another, it confuses the fsck out of sparse. Use unsigned long or uintptr_t instead. There are several places misusing ptrdiff_t; fixed.

2007-10-29[BLOCK] Fix bad sharing of tag busy list on queues with shared tag mapsJens Axboe2-6/+4
For the locking to work, only the tag map and tag bit map may be shared (incidentally, I was just explaining this to Nick yesterday, but I apparently didn't review the code well enough myself). But we also share the busy list! The busy_list must be queue private, or we need a block_queue_tag covering lock as well. So we have to move the busy_list to the queue. This'll work fine, and it'll actually also fix a problem with blk_queue_invalidate_tags() which will invalidate tags across all shared queues. This is a bit confusing, the low level driver should call it for each queue seperately since otherwise you cannot kill tags on just a single queue for eg a hard drive that stops responding. Since the function has no callers currently, it's not an issue. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-10-27x86: Dump filtering supports x86_64 sparsememKen'ichi Ohmichi1-0/+2
This patch adds the symbol "init_level4_pgt" to the vmcoreinfo data so that makedumpfile (dump filtering command) supports x86_64 sparsemem kernel of linux-2.6.24. makedumpfile creates a small dumpfile by excluding unnecessary pages for the analysis. It checks attributes in page structures and distinguishes necessary pages and unnecessary ones. To check them, makedumpfile gets the vmcoreinfo data which has the minimum debugging information only for dump filtering. For older x86_64 kernel (linux-2.6.23 or before), makedumpfile translates the virtual address of page structure into physical address by subtracting PAGE_OFFSET from virtual address, but this translation isn't effective for linux-2.6.24 sparsemem kernel, because its page structures are in virtual memmap area. makedumpfile should translate their virtual address by 4-levels paging and it needs the symbol "init_level4_pgt".
