The timer LED is unusable at HZ=large, since it's got a hard-wired value of 100 ticks per cycle; when HZ=1024 (for example) it's essentially always-on. This patch just makes that be HZ ticks per cycle. Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This is a rework of the ixp4xx irq_chip implementation. The use of two irq_chip structures and potentially switching between them is a violation of the intended use of the IRQ framework. The current implementation does not work with current in-kernel spinlock debugging or lockdep due to lock recursion problems caused by calling set_irq_chip/handler from within the chip's set_irq_type(). This patch goes back to using one irq_chip structure and handling the differences between edge/level, normal/GPIO interrupts inside the ack/mask/unmask routines themselves.

It turns out that the linker warnings on 64-bit powerpc about "section blah exceeds stub group size" were being triggered by conditional branches in head_64.S branching to global symbols, whether in head_64.S or in other files. This eliminates the warnings by making some global symbols in head_64.S no longer global, and by rearranging some branches. Signed-off-by: NPaul Mackerras <paulus@samba.org> [ Yee-haa.

Since the "mask" bit is in the low word, when we write a new entry, we need to write the high word first, before we potentially unmask it. The exception is when we actually want to mask the interrupt, in which case we want to write the low word first to make sure that the high word doesn't change while the interrupt routing is still active.

The alignment exception used to only check the exception table for -EFAULT, not for other errors. That opens an oops window if we can coerce the kernel into getting an alignment exception for other reasons in what would normally be a user-protected accessor, which can be done via some of the futex ops.

If mmiowb() is always used prior to releasing spinlock as Doc suggests, then it's safe against preemption; but I'm not convinced that's always the case. If preemption occurs between sync and get_paca()->io_sync = 0, I believe there's no problem. But in the unlikely event that gcc does the store relative to another register than r13 (as it did with current), then there's a small danger of setting another cpu's io_sync to 0, after it had just set it to 1. Rewrite ppc64 mmiowb to prevent that. The remaining io_sync assignments in io.h all get_paca()->io_sync = 1, which is harmless even if preempted to the wrong cpu (the context switch itself syncs); and those in spinlock.h are while preemption is disabled.

Repeated -j20 kernel builds on a G5 Quad running an SMP PREEMPT kernel would often collapse within a day, some exec failing with "Bad address". In each case examined, load_elf_binary was doing a kernel_read, but generic_file_aio_read's access_ok saw current->thread.fs.seg as USER_DS instead of KERNEL_DS. objdump of filemap.o shows gcc 4.1.0 emitting "mr r5,r13 ... ld r9,416(r5)" here for get_paca()->__current, instead of the expected and much more usual "ld r9,416(r13)"; I've seen other gcc4s do the same, but perhaps not gcc3s. So, if the task is preempted and rescheduled on a different cpu in between the mr and the ld, r5 will be looking at a different paca_struct from the one it's now on, pick up the wrong __current, and perhaps the wrong seg. Presumably much worse could happen elsewhere, though that split is rare. Other architectures appear to be safe (x86_64's read_pda is more limiting than get_paca), but ppc64 needs to force "current" into one instruction.

The 10Gigabit ethernet device drivers appear to be able to chew up all 256MB of TCE mappings on pSeries systems, as evidenced by numerous error messages: iommu_alloc failed, tbl c0000000010d5c48 vaddr c0000000d875eff0 npages 1 Some experimentation indicates that this is essentially because one 1500 byte ethernet MTU gets mapped as a 64K DMA region when the large 64K pages are enabled. Thus, it doesn't take much to exhaust all of the available DMA mappings for a high-speed card. This patch changes the iommu allocator to work with its own unique, distinct page size. Although the patch is long, its actually quite simple: it just #defines a distinct IOMMU_PAGE_SIZE and then uses this in all the places that matter. As a side effect, it also dramatically improves network performance on platforms with H-calls on iommu translation inserts/removes (since we no longer call it 16 times for a 1500 bytes packet when the iommu HW is still 4k). In the future, we might want to make the IOMMU_PAGE_SIZE a variable in the iommu_table instance, thus allowing support for different HW page sizes in the iommu itself.

Fixed a compile error in building the 85xx support with oprofile, and in the process cleaned up some issues with the fsl_booke performance monitor code. * Reorganized FSL Book-E performance monitoring code so that the 7450 wouldn't be built if the e500 was, and cleaned it up so it was more self-contained. * Added a cpu_setup function for FSL Book-E. The original cpu_setup function prototype had no arguments, assuming that the reg_setup function would copy the required information into variables which represented the registers. This was silly for e500, since it has 1 register per counter (rather than 3 for all counters), so the code has been restructured to have cpu_setup take the current counter config array as an argument, with op_powerpc_setup() invoking op_powerpc_cpu_setup() through on_each_cpu(), and op_powerpc_cpu_setup() invoking the model-specific cpu_setup function with an argument. The argument is ignored on all other platforms at present. * Fixed a confusing line where a trinary operator only had two arguments Signed-off-by: NAndrew Fleming <afleming@freescale.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

This patch fixes a few issues in offb: - A test was inverted causing the palette hack to never work (no device node was passed down to the init function) - Some cards seem to have their assigned-addresses property in a random order, thus we need to try using of_get_pci_address() first, which will fail if it's not a PCI device, and fallback to of_get_address() in that case. of_get_pci_address() properly parsees assigned-addresses to test the BAR number and thus will get it right whatever the order is. - Some cards (like GXT4500) provide a linebytes of 0xffffffff in the device-tree which does no good. This patch handles that by using the screen width when that happens. (Also fixes btext.c while at it). - Add detection of the GXT4500 in addition to the GXT2000 for the palette hacks (we use the same hack, palette is linear in register space at offset 0x6000).

sis_init_one() modifies probe_ent->port_flags after allocating and initializing it using ata_pci_init_native_mode(). This makes port_flags for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting in misdetection of device due to incorrectly initialized SCR access flag. This patch make probe_ent alloc/init happen after the final port flags value is determined.

The sky2 driver uses a single NAPI poll routine for both ports on dual ported cards (because there is a single IRQ and status ring). Netpoll makes assumptions about the relationship between network device and NAPI that aren't correct on the second port, this will cause the port to never clear work. Most systems, just have single port, so not a big issue. The easy fix is just make the second port, not netpoll capable.
