2008-05-08sh: intc register modify fixMagnus Damm
Make sure register modifications stay atomic. Fixes processors with shared priority register masking. Dual bitmap masking is unaffected. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: no high level trigger on some sh3 cpusMagnus Damm
The processor models sh7706, sh7707 and sh7709 don't support high level trigger sense configuration. And the intc code looks like crap these days so what's the difference. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: clean up sh7710 and sh7720 intc tablesMagnus Damm
Clean up the intc tables by removing unneeded #ifdefs. The vector list is what selects which interrupt sources that should be added, having unsupported bitfields listed is ok as long as the vector is excluded from the list. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: add interrupt ack code to sh3Magnus Damm
This patch adds interrupt acknowledge code for external interrupt sources on sh3 processors. Only really required for edge triggered interrupts, but we ack regardless of sense configuration. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: unify external irq pin code for sh3Magnus Damm
This patch unifies the sh3 external irq pin code. It buys us some savings with reduced code redundancy, but the main feature with this change is irq sense selection support for all sh3 processors. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh-sci: avoid writing to nonexistent registersMagnus Damm

2008-05-08sh-sci: sh7722 lacks scsptr registersMagnus Damm
The sh7722 serial ports all lack SCSPTR registers, so mark them as nonexistent in the register table. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh-sci: improve sh7722 supportMagnus Damm

2008-05-08sh: drain and wait for early printkMagnus Damm
Drain by waiting for all characters to be sent, and make sure to wait a little bit after setting up the baud rate. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: use sci_out() for early printkMagnus Damm
Use sci_out() instead of ctrl_outw() for early printk setup code. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-08sh: add memory resources to /proc/iomemMagnus Damm
Add physical memory resources such as System RAM, Kernel code/data/bss and reserved crash dump area to /proc/iomem. Same strategy as on x86. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

We clobber %i1 as well as %i0 for these system calls, because they give two return values.

2008-05-06x86: fix PAE pmd_bad bootup warningHugh Dickins
Fix warning from pmd_bad() at bootup on a HIGHMEM64G HIGHPTE x86_32. That came from 9fc34113f6880b215cbea4e7017fc818700384c2 x86: debug pmd_bad(); but we understand now that the typecasting was wrong for PAE in the previous version: pagetable pages above 4GB looked bad and stopped Arjan from booting. And revert that cded932b75ab0a5f9181ee3da34a0a488d1a14fd x86: fix pmd_bad and pud_bad to support huge pages. It was the wrong way round: we shouldn't weaken every pmd_bad and pud_bad check to let huge pages slip through - in part they check that we _don't_ have a huge page where it's not expected. Put the x86 pmd_bad() and pud_bad() definitions back to what they have long been: they can be improved (x86_32 should use PTE_MASK, to stop PAE thinking junk in the upper word is good; and x86_64 should follow x86_32's stricter comparison, to stop thinking any subset of required bits is good); but that should be a later patch. Fix Hans' good observation that follow_page() will never find pmd_huge() because that would have already failed the pmd_bad test: test pmd_huge in between the pmd_none and pmd_bad tests. Tighten x86's pmd_huge() check? No, once it's a hugepage entry, it can get quite far from a good pmd: for example, PROT_NONE leaves it with only ACCESSED of the KERN_PGTABLE bits. However... though follow_page() contains this and another test for huge pages, so it's nice to keep it working on them, where does it actually get called on a huge page? get_user_pages() checks is_vm_hugetlb_page(vma) to to call alternative hugetlb processing, as does unmap_vmas() and others.

2008-05-06[PATCH] fix SMP ordering hole in fcntl_setlk()Al Viro
fcntl_setlk()/close() race prevention has a subtle hole - we need to make sure that if we *do* have an fcntl/close race on SMP box, the access to descriptor table and inode->i_flock won't get reordered. As it is, we get STORE inode->i_flock, LOAD descriptor table entry vs. STORE descriptor table entry, LOAD inode->i_flock with not a single lock in common on both sides. We do have BKL around the first STORE, but check in locks_remove_posix() is outside of BKL and for a good reason - we don't want BKL on common path of close(2). Solution is to hold ->file_lock around fcheck() in there; that orders us wrt removal from descriptor table that preceded locks_remove_posix() on close path and we either come first (in which case eviction will be handled by the close side) or we'll see the effect of close and do eviction ourselves. Note that even though it's read-only access, we do need ->file_lock here - rcu_read_lock() won't be enough to order the things. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2008-05-06[PATCH] kill ->put_inodeChristoph Hellwig
And with that last patch to affs killing the last put_inode instance we can finally, after many years of transition kill this racy and awkward interface. (It's kinda funny that even the description in Documentation/filesystems/vfs.txt was entirely wrong..) Also remove a very misleading comment above the defintion of struct super_operations.

2008-05-06[PATCH] fix reservation discarding in affsRoman Zippel
- remove affs_put_inode, so preallocations aren't discared unnecessarily often. - remove affs_drop_inode, it's called with a spinlock held, so it can't use a mutex. - make i_opencnt atomic - avoid direct b_count manipulations - a few allocation failure fixes, so that these are more gracefully handled now.

2008-05-06pata_atiixp: Don't disableAlan Cox
A couple of distributions (Fedora, Ubuntu) were having weird problems with the ATI IXP series PATA controllers being reported as simplex. At the heart of the problem is that both distros ignored the recommendations to load pata_acpi and ata_generic *AFTER* specific host drivers. The underlying cause however is that if you D3 and then D0 an ATI IXP it helpfully throws away some configuration and won't let you rewrite it. Add checks to ata_generic and pata_acpi to pin ATIIXP devices. Possibly the real answer here is to quirk them and pin them, but right now we can't do that before they've been pcim_enable()'d by a driver. I'm indebted to David Gero for this. His bug report not only reported the problem but identified the cause correctly and he had tested the right values to prove what was going on [If you backport this for 2.6.24 you will need to pull in the 2.6.25 removal of the bogus WARN_ON() in pcim_enagle] Signed-off-by: Alan Cox <alan@redhat.com> Tested-by: David Gero <davidg@havidave.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
