      [PATCH] arch/i386/pci/irq.c - new VIA chipsets (fwd) · 40d8b89b
      由 Grzegorz Janoszka 提交于 
      I use 2.6.15.6 Linux kernel and found some problems. I have about 100
Linux boxes (all with the same (binary the same) kernel). Last time I have
upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2,
.4 and .6) and I have found some problems on VIA based PC's. Probably the
reason of this is that some VIA chipsets are unrecognized by IRQ router.

In line 586 there is: /* FIXME: add new ones for 8233/5 */

There were only a few of chipsets ID's there, some of my VIA chipsets were
not present and kernel used default IRQ router.

I have added three entries, so that the code looks like:

        case PCI_DEVICE_ID_VIA_82C596:
        case PCI_DEVICE_ID_VIA_82C686:
        case PCI_DEVICE_ID_VIA_8231:
        case PCI_DEVICE_ID_VIA_8233A:
        case PCI_DEVICE_ID_VIA_8235:
        case PCI_DEVICE_ID_VIA_8237:
        case PCI_DEVICE_ID_VIA_8237_SATA:
                /* FIXME: add new ones for 8233/5 */
                r->name = "VIA";
                r->get = pirq_via_get;
                r->set = pirq_via_set;
                return 1;
        }

The kernel goes fine but I haven't testes it for weeks, I'm just a moment
after reboot :)
One thing is different (better?):
Using previus kernel I had:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0
now I have:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11

Maybe it is good idea to add there some more VIA chipsets?
The ones I have added seem to be OK.

      [PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/ · 4f705ae3
      由 Bjorn Helgaas 提交于 
      dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64.
Currently all three arches compile it from arch/i386, which means that ia64
and x86_64 depend on things in arch/i386 that they wouldn't otherwise care
about.

This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing
trailing whitespace) and the associated Makefile changes.  All three
architectures already set CONFIG_DMI in their top-level Kconfig files.

      [PATCH] sys_sync_file_range() · f79e2abb
      由 Andrew Morton 提交于 
      Remove the recently-added LINUX_FADV_ASYNC_WRITE and LINUX_FADV_WRITE_WAIT
fadvise() additions, do it in a new sys_sync_file_range() syscall instead.
Reasons:

- It's more flexible.  Things which would require two or three syscalls with
  fadvise() can be done in a single syscall.

- Using fadvise() in this manner is something not covered by POSIX.

The patch wires up the syscall for x86.

The sycall is implemented in the new fs/sync.c.  The intention is that we can
move sys_fsync(), sys_fdatasync() and perhaps sys_sync() into there later.

Documentation for the syscall is in fs/sync.c.

A test app (sync_file_range.c) is in
http://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz.

The available-to-GPL-modules do_sync_file_range() is for knfsd: "A COMMIT can
say NFS_DATA_SYNC or NFS_FILE_SYNC.  I can skip the ->fsync call for
NFS_DATA_SYNC which is hopefully the more common."

Note: the `async' writeout mode SYNC_FILE_RANGE_WRITE will turn synchronous if
the queue is congested.  This is trivial to fix: add a new flag bit, set
wbc->nonblocking.  But I'm not sure that we want to expose implementation
details down to that level.

Note: it's notable that we can sync an fd which wasn't opened for writing.
Same with fsync() and fdatasync()).

Note: the code takes some care to handle attempts to sync file contents
outside the 16TB offset on 32-bit machines.  It makes such attempts appear to
succeed, for best 32-bit/64-bit compatibility.  Perhaps it should make such
requests fail...

      [PATCH] Don't pass boot parameters to argv_init[] · 9b41046c
      由 OGAWA Hirofumi 提交于 
      The boot cmdline is parsed in parse_early_param() and
parse_args(,unknown_bootoption).

And __setup() is used in obsolete_checksetup().

	start_kernel()
		-> parse_args()
			-> unknown_bootoption()
				-> obsolete_checksetup()

If __setup()'s callback (->setup_func()) returns 1 in
obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
handled.

If ->setup_func() returns 0, obsolete_checksetup() tries other
->setup_func().  If all ->setup_func() that matched a parameter returns 0,
a parameter is seted to argv_init[].

Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
If the app doesn't ignore those arguments, it will warning and exit.

This patch fixes a wrong usage of it, however fixes obvious one only.

      [PATCH] Mark unwind info for signal trampolines in vDSOs · da2e9e1f
      由 Jakub Jelinek 提交于 
      Mark unwind info for signal trampolines using the new S augmentation flag
introduced in: http://gcc.gnu.org/PR26208.

GCC 4.2 (or patched earlier GCC) will be able to special case unwinding
through frames right above signal trampolines.  As the augmentations start
with z flag and S is at the very end of the augmentation string, older GCCs
will just skip the S flag as unknown (that's why an augmentation flag was
chosen over say a new CFA opcode).
