Hi,
Seems there is something wrong with the server that multiple dumplications
of the v3 patches were sent out, please ignore the rest and take this newest
series as formal count.

Which series ?

It seems you sent 3 times, at 9:29, 9:41 and 9:49 (Paris Time)

From the series of 9:29, I received patches 0 to 3
From the series of 9:41, I received patches 0 to 3
From the series of 9:49, I received patches 0 and 4.

Looks like powerpc patchwork 
(https://patchwork.ozlabs.org/project/linuxppc-dev/list/?submitter=78320) 
got:
From the series of 9:29, I received patches 0 to 4
From the series of 9:41, I received patches 1 to 4
From the series of 9:49, I received patches 1 to 4

So this seems to be something wrong somewhere.

Christophe

Hi Christophe,
Sorry again, and I don't know which best fit you all. I guess a RESEND tag might help.
So I will send another series with RESEND tag, please just drop all this three.

Hope that relly won't trouble you yelling, and hope the mail server would work well.

Thanks,
Wenhu

Subject: [PATCH v3,0/4] drivers: uio: new driver uio_fsl_85xx_cache_sram>This series add a new uio driver for freescale 85xx platforms to

access the Cache-Sram form user level. This is extremely helpful
for the user-space applications that require high performance memory
accesses.

It fixes the compile errors and warning of the hardware level drivers
and implements the uio driver in uio_fsl_85xx_cache_sram.c.

Changes since v1:
* Addressed comments from Greg K-H
* Moved kfree(info->name) into uio_info_free_internal()

Changes since v2:
* Drop the patch that modifies Kconfigs of arch/powerpc/platforms
   and modified the sequence of patches:
    01:dropped, 02->03, 03->02, 04->01, 05->04
* Addressed comments from Greg, Scott and Christophe
* Use "uiomem->internal_addr" as if condition for sram memory free,
   and memset the uiomem entry
* Modified of_match_table make the driver apart from Cache-Sram HW info
   which belong to the HW level driver fsl_85xx_cache_sram to match
* Use roundup_pow_of_two for align calc(really learned a lot from Christophe)
* Remove useless clear block of uiomem entries.
* Use UIO_INFO_VER micro for info->version, and define it as
   "devicetree,pseudo", meaning this is pseudo device and probed from
   device tree configuration
* Select FSL_85XX_CACHE_SRAM rather than depends on it
