2008-04-30tty: The big operations reworkAlan Cox1-4/+7
- Operations are now a shared const function block as with most other Linux objects - Introduce wrappers for some optional functions to get consistent behaviour - Wrap put_char which used to be patched by the tty layer - Document which functions are needed/optional - Make put_char report success/fail - Cache the driver->ops pointer in the tty as tty->ops - Remove various surplus lock calls we no longer need - Remove proc_write method as noted by Alexey Dobriyan - Introduce some missing sanity checks where certain driver/ldisc combinations would oops as they didn't check needed methods were present [akpm@linux-foundation.org: fix fs/compat_ioctl.c build] [akpm@linux-foundation.org: fix isicom] [akpm@linux-foundation.org: fix arch/ia64/hp/sim/simserial.c build] [akpm@linux-foundation.org: fix kgdb] Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Cc: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-04-30signals: x86 TS_RESTORE_SIGMASKRoland McGrath3-17/+18
Replace TIF_RESTORE_SIGMASK with TS_RESTORE_SIGMASK and define our own set_restore_sigmask() function. This saves the costly SMP-safe set_bit operation, which we do not need for the sigmask flag since TIF_SIGPENDING always has to be set too.

2008-04-30pxafb: convert fb driver to use ioremap() and __raw_{readl, writel}eric miao1-5/+0
This is part of the effort moving peripheral registers outside of pxa-regs.h, and using ioremap() make it possible the same IP can be re-used on different processors with different registers space As a result, the fixed mapping in pxa_map_io() is removed. The regs-lcd.h can actually moved to where closer to pxafb.c but some of its bit definitions are directly used by various platform code, though this is not a good style.

2008-04-29[IA64] Provide ACPI fixup for /proc/cpuinfo/physical_idAlex Chiang1-0/+9
Legacy HP ia64 platforms currently cannot provide /proc/cpuinfo/physical_id due to legacy SAL/PAL implementations. However, that physical topology information can be obtained via ACPI. Provide an interface that gives ACPI one last chance to provide physical_id for these legacy platforms. This logic only comes into play iff: - ACPI actually provides slot information for the CPU - we lack a valid socket_id Otherwise, we don't do anything. Since x86 uses the ACPI processor driver as well, we provide a nop stub function for arch_fix_phys_package_id() in asm-x86/topology.h Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2008-04-29i2c: Convert most new-style drivers to use module aliasingJean Delvare24-69/+31
Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

2008-04-29[IA64] Remove printk noise on unimplemented SAL_PHYSICAL_ID_INFOAlex Chiang1-3/+9
Commit 113134fcbca83619be4c68d0ca66db6093777b5d changed the flow of control when calling PAL_LOGICAL_TO_PHYSICAL and SAL_PHYSICAL_ID_INFO. With the change, if a platform did not implement the latter, a useless printk would appear in the boot log: ia64_sal_pltid failed with -1 So let's check the return code and only printk on a true error, and do not print anything in the unimplemented case. While we're in there, clean up some stylistic issues too. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
