      Detach sched.h from mm.h · e8edc6e0
      Alexey Dobriyan 提交于
      First thing mm.h does is including sched.h solely for can_do_mlock() inline
      function which has "current" dereference inside. By dealing with can_do_mlock()
      mm.h can be detached from sched.h which is good. See below, why.
      
      This patch
      a) removes unconditional inclusion of sched.h from mm.h
      b) makes can_do_mlock() normal function in mm/mlock.c
      c) exports can_do_mlock() to not break compilation
      d) adds sched.h inclusions back to files that were getting it indirectly.
      e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
         getting them indirectly
      
      Net result is:
      a) mm.h users would get less code to open, read, preprocess, parse, ... if
         they don't need sched.h
      b) sched.h stops being dependency for significant number of files:
         on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
         after patch it's only 3744 (-8.3%).
      
      Cross-compile tested on
      
      	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
      	alpha alpha-up
      	arm
      	i386 i386-up i386-defconfig i386-allnoconfig
      	ia64 ia64-up
      	m68k
      	mips
      	parisc parisc-up
      	powerpc powerpc-up
      	s390 s390-up
      	sparc sparc-up
      	sparc64 sparc64-up
      	um-x86_64
      	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig
      
      as well as my two usual configs.

      Fix assertion failure with MSI on sparc64 · b3b7cc7b
      David Miller 提交于
      Today's find is a triggered assertion in msi_free_irqs() when the system
      doesn't support MSI, in which case arch_setup_msi_irqs() always returns
      an error.
      
      The problem is that when this happens we branch into msi_free_irqs(), to
      which you added the following assertion loop:
      
      	list_for_each_entry(entry, &dev->msi_list, list)
      		BUG_ON(irq_has_action(entry->irq));
      
      Well, if arch_setup_msi_irqs() fails, entry->irq will be zero and
      although that's never assigned to any normal devices we use that IRQ
      number for the timer interrupt on sparc64 so this assertion triggers.
      
      Better to test for zero before doing the irq_has_action() assertion
      thing.

      Add the combined mode for ATI SB700 · 82377718
      Henry Su 提交于
      Besides those modes in ATI SB600 SATA controller, ATI SB700 supports one
      more mode:the combined mode.
      
      The combined mode is a Legacy IDE mode used for compatibility with some old
      OS without AHCI driver, but now it is not necessary for Linux since the
      kernel has supported AHCI.
