libata: always use polling SETXFER

Several people have reported LITE-ON LTR-48246S detection failed
because SETXFER fails.  It seems the device raises IRQ too early after
SETXFER.  This is controller independent.  The same problem has been
reported for different controllers.

So, now we have pata_via where the controller raises IRQ before it's
ready after SETXFER and a device which does similar thing.  This patch
makes libata always execute SETXFER via polling.  As this only happens
during EH, performance impact is nil.  Setting ATA_TFLAG_POLLING is
also moved from issue hot path to ata_dev_set_xfermode() - the only
place where SETXFER can be issued.

Note that ATA_TFLAG_POLLING applies only to drivers which implement
SFF TF interface and use libata HSM.  More advanced controllers ignore
the flag.  This doesn't matter for this fix as SFF TF controllers are

Based upon an excellent bug report and initial patch by
Frederik Deweerdt.

The UNIX datagram connect code blindly dereferences other->sk_socket
via the call down to the security_unix_may_send() function.

Without locking 'other' that pointer can go NULL via unix_release_sock()
which does sock_orphan() which also marks the socket SOCK_DEAD.

So we have to lock both 'sk' and 'other' yet avoid all kinds of
potential deadlocks (connect to self is OK for datagram sockets and it
is possible for two datagram sockets to perform a simultaneous connect
to each other).  So what we do is have a "double lock" function similar
to how we handle this situation in other areas of the kernel.  We take
the lock of the socket pointer with the smallest address first in
order to avoid ABBA style deadlocks.

Once we have them both locked, we check to see if SOCK_DEAD is set
for 'other' and if so, drop everything and retry the lookup.

those pages exist in any TLB, thus causing potential access to

However, our tlb_flush only triggers the RCU for freeing page

ALPHA: support graphics on non-zero PCI domains

This code replaces earlier and incomplete handling of graphics on non-zero PCI
domains (aka hoses or peer PCI buses).

An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a
kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose
SRM consoles are capable of configuring and handling graphics options on
non-zero hoses.  All other machines have the option set FALSE.

A routine, "find_console_vga_hose()", is used to find the graphics device
which the machine's firmware believes is the console device, and it sets a
global (pci_vga_hose) for later use in managing access to the device.  This is
called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a
custom version of this routine because of extra complexity.

A routine, "locate_and_init_vga()", is used to find the graphics device and
set a global (pci_vga_hose) for later use in managing access to the device, in
the case where "find_console_vga_hose" has failed.

Various adjustments are made to the ioremap and ioportmap routines for
detecting and translating "legacy" VGA register and memory references to the
real PCI domain.

When either rx_buf or tx_buf is not being used, i.e.  for plain read- or

the transfer is longer than the size of this buffer, it is split into
multiple DMA transfers.

When the transfer is split like this, the atmel_spi driver ends up using
the same DMA address again and again even for the buffer that came from the

the quality of the submission and cause unnessary work for reviewers.

As a first step package up the current state of the patch style checker and
include it in the kernel tree.  Add instructions suggesting running it on

17 years agofbdev: Move declaration of fb_class to <linux/fb.h>

fbdev: Move declaration of fb_class to <linux/fb.h>

Move the forward declaration of fb_class from drivers/video/console/fbcon.h to
<linux/fb.h>, together with the other forward declarations related to
drivers/video/fbmem.c.

This kills the following sparse warning:
| drivers/video/fbmem.c:1363:14: warning: symbol 'fb_class' was not declared. Should it be static?

17 years agocfag12864bfb: Use sys_ instead of cfb_ framebuffer accessors

cfag12864bfb: Use sys_ instead of cfb_ framebuffer accessors

Because the framebuffer memory is allocated system RAM, use the sys_ drawing
libraries. It also fixes the following compile error:

  LD      .tmp_vmlinux1
drivers/built-in.o:(.data+0x8b48): undefined reference to `cfb_fillrect'
drivers/built-in.o:(.data+0x8b50): undefined reference to `cfb_copyarea'
drivers/built-in.o:(.data+0x8b58): undefined reference to `cfb_imageblit'

[adaplas]
Use fb_sys_read/write for the same reasons as above.

fix compat futex code for private futexes

When the private futex support was added the compat code wasn't changed.
The result is that code using compat code which fail, e.g., because the
timeout values are not correctly passed.  The following patch should fix
that.
