Re: [RFC PATCH 1/8] mm, vmalloc: change iterating a vmlist to find_vm_area()

2012-12-09 Thread guanxuetao

 The purpose of iterating a vmlist is finding vm area with specific
 virtual address. find_vm_area() is provided for this purpose
 and more efficient, because it uses a rbtree.
 So change it.

I used following command to generate a signed tag.
  'git tag for-linus -s -u g...@mprc.pku.edu.cn'
Then, I pushed this tag into github.com by:
  'git push github -f --tags'
Finally, I checked github repo, and tag 'for-linus' can be found.

Could you tell me what's wrong with my operation?

Thanks & Regards,
Guan Xuetao

Re: [PATCH] asm-generic/io.h: remove asm/cacheflush.h include

2012-10-28 Thread guanxuetao

 Including asm/cacheflush.h from asm-generic/io.h prevents
 cacheflush.h being able to use I/O functions like readl and writel due
 to circular include dependencies. It doesn't appear as if anything from
 cacheflush.h is actually used by the generic io.h, so remove the
 include.

 I've compile tested a defconfig compilation of blackfin, openrisc (which
 needed asm/pgtable.h including from it's asm/io.h to get the PAGE_*
 definitions), and xtensa.

 Other architectures which use asm-generic/io.h are score and unicore32,
 and looking at their io.h I don't see any obvious problems.

I merged the uapi patch for unicore32.
In that patch, kvm_para.h was moved to
arch/unicore32/include/uapi/asm/kvm_para.h.
Anyway, I'd like to apply this patch based on uapi modification.

2012-10-13 Thread guanxuetao

 From: Steven Rostedt srost...@redhat.com

 All the headers but kvm_para.h use the Kbuild infrastructure to
 get to the asm-generic headers.

I merged the uapi patch for unicore32.
In that patch, kvm_para.h was moved to
arch/unicore32/include/uapi/asm/kvm_para.h.
Anyway, I'd like to apply this patch based on uapi modification.

Re: [PATCH v2 2/5] unicore32: pwm: Use module_platform_driver()

2012-09-21 Thread guanxuetao

 Some of the boilerplate code can be eliminated by using this macro. The
 driver was previously registered with an arch_initcall(), so technically
 this is no longer the same, but when the driver is moved to the PWM
 framework, deferred probing will take care of any driver probe ordering
 issues.

 Calling the actual probing function through a proxy isn't required and
 makes the code needlessly complex.

Could you disintegrate it into several small patches, so I could check it

I think old register names could be used here by some small modifications.
Please see arch/unicore32/include/mach/regs-ost.h
We can avoid ioremap and use writel/readl directly on these registers.

Re: [PATCH 1/6] unicore32: pwm: Properly remap memory-mapped registers

2012-09-06 Thread guanxuetao

 Instead of writing to the timer controller registers by dereferencing a
 pointer to the memory location, properly remap the memory region with a
 call to ioremap_nocache() and access the registers using writel().

 This commit adds support for the common clock framework to the Unicore32

This patch can't work.
Could you disintegrate it into several small patches, so I could check it

 callback through a struct dev_pm_ops object rather than by using
 a legacy PM hook in struct platform_driver.  The empty resume
 callback is not necessary, so remove it.
