      module: add /sys/module/<name>/uevent files · 88bfa324
      由 Kay Sievers 提交于 
      Userspace wants to manage module parameters with udev rules.
This currently only works for loaded modules, but not for
built-in ones.

To allow access to the built-in modules we need to
re-trigger all module load events that happened before any
userspace was running. We already do the same thing for all
devices, subsystems(buses) and drivers.

This adds the currently missing /sys/module/<name>/uevent files
to all module entries.

      module: change attr callbacks to take struct module_kobject · 4befb026
      由 Kay Sievers 提交于 
      This simplifies the next patch, where we have an attribute on a
builtin module (ie. module == NULL).

      modules: add default loader hook implementations · 74e08fcf
      由 Jonas Bonn 提交于 
      The module loader code allows architectures to hook into the code by
providing a small number of entry points that each arch must implement.
This patch provides __weakly linked generic implementations of these
entry points for architectures that don't need to do anything special.

      KVM: MMU: filter out the mmio pfn from the fault pfn · fce92dce
      由 Xiao Guangrong 提交于 
      If the page fault is caused by mmio, the gfn can not be found in memslots, and
'bad_pfn' is returned on gfn_to_hva path, so we can use 'bad_pfn' to identify
the mmio page fault.
And, to clarify the meaning of mmio pfn, we return fault page instead of bad
page when the gfn is not allowd to prefetch

      ata: Add and use ata_print_version_once · 06296a1e
      由 Joe Perches 提交于 
      Use a single mechanism to show driver version.
Reduces text a tiny bit too.

Remove uses of static int printed_version
Add and use ata_print_version(const struct device *, const char *ver)
and ata_print_version_once.

      ata: Convert ata_<foo>_printk(KERN_<LEVEL> to ata_<foo>_<level> · a9a79dfe
      由 Joe Perches 提交于 
      Saves text by removing nearly duplicated text format strings by
creating ata_<foo>_printk functions and printf extension %pV.

ata defconfig size shrinks ~5% (~8KB), allyesconfig ~2.5% (~13KB)

Format string duplication comes from:

 #define ata_link_printk(link, lv, fmt, args...) do { \
       if (sata_pmp_attached((link)->ap) || (link)->ap->slave_link)    \
               printk("%sata%u.%02u: "fmt, lv, (link)->ap->print_id,   \
                      (link)->pmp , ##args); \
       else \
               printk("%sata%u: "fmt, lv, (link)->ap->print_id , ##args); \
       } while(0)

Coalesce long formats.
