* [SPARC64]: Kill off dummy_tick_ops.David S. Miller2005-11-07
| | | | | | | | It only serves to generate false-positive buildcheck warnings. Just set it initially to tick_operations which uses the v9 %tick register which every sparc64 processor has. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] mm: Do not flush TLB mm in tlb_finish_mmu()David S. Miller2005-11-07
| | | | | | | | | | It isn't needed any longer, as noted by Hugh Dickins. We still need the flush routines, due to the one remaining call site in hugetlb_prefault_arch_hook(). That can be eliminated at some later point, however. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] mm: context switch ptlockHugh Dickins2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | sparc64 is unique among architectures in taking the page_table_lock in its context switch (well, cris does too, but erroneously, and it's not yet SMP anyway). This seems to be a private affair between switch_mm and activate_mm, using page_table_lock as a per-mm lock, without any relation to its uses elsewhere. That's fine, but comment it as such; and unlock sooner in switch_mm, more like in activate_mm (preemption is disabled here). There is a block of "if (0)"ed code in smp_flush_tlb_pending which would have liked to rely on the page_table_lock, in switch_mm and elsewhere; but its comment explains how dup_mmap's flush_tlb_mm defeated it. And though that could have been changed at any time over the past few years, now the chance vanishes as we push the page_table_lock downwards, and perhaps split it per page table page. Just delete that block of code. Which leaves the mysterious spin_unlock_wait(&oldmm->page_table_lock) in kernel/fork.c copy_mm. Textual analysis (supported by Nick Piggin) suggests that the comment was written by DaveM, and that it relates to the defeated approach in the sparc64 smp_flush_tlb_pending. Just delete this block too. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] mm: don't re-evaluate *ptepHugh Dickins2005-11-07
| | | | | | | | | | sparc64 prom_callback and new_setup_frame32 each operates on a user page table without holding lock, and no doubt they've good reason. But I'd feel more confident if they were to do a "pte = *ptep" and then operate on pte, rather than re-evaluating *ptep. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: David S.

| * [ARM] 3121/1: unconditionally use XCB=101 on ixp2000Lennert Buytenhek2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | Patch from Lennert Buytenhek Since we have to use XCB=101 instead of XCB=000 on the ixp2400 to prevent it from regularly falling over, and since we have to deal with manual write buffer flushing because of that, we might as well use XCB=101 on all ixp2000 platforms since it's faster than XCB=000.

| * [ARM] 3118/1: fix and reenable nwfpe extended precision emulation for big-endianLennert Buytenhek2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Lennert Buytenhek nwfpe extended precision emulation used to be broken on big-endian and was therefore disabled. This patch fixes nwfpe so that it copies extended precision floats to/from userspace in the proper word order (similar to patch #2046, see the description of that patch for an explanation) and reenables the Kconfig option.

| * [ARM] 3117/1: nwfpe kernel memory info leakLennert Buytenhek2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Lennert Buytenhek The routine that nwfpe uses for converting floats/doubles to extended precision fails to zero two bytes of kernel stack. This is not immediately obvious, as the floatx80 structure has 16 bits of implicit padding (by design.) These two bytes are copied to userspace when an stfe is emulated, causing a possible info leak. Make the padding explicit and zero it out in the relevant places. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Via reading the code, my understanding is that powernow-k8 uses preempt_disable to ensure that driver->target doesn't migrate across cpus whilst it's accessing per processor registers, however set_cpus_allowed will provide this for us. Additionally, remove schedule() calls from set_cpus_allowed as set_cpus_allowed ensures that you're executing on the target processor on return.
