      md: Don't wait UNINTERRUPTIBLE for other resync to finish · 9744197c
      由 NeilBrown 提交于 
      When two md arrays share some block device (e.g each uses different
partitions on the one device), a resync of one array will wait for
the resync on the other to finish.

This can be a long time and as it currently waits TASK_UNINTERRUPTIBLE,
the softlockup code notices and complains.

So use TASK_INTERRUPTIBLE instead and make sure to flush signals
before calling schedule.

      e100: Use pci_pme_active to clear PME_Status and disable PME# · e7272403
      由 Rafael J. Wysocki 提交于 
      Currently e100 uses pci_enable_wake() to clear pending wake-up events
and disable PME# during intitialization, but that function is not
suitable for this purpose, because it immediately returns error code
if device_may_wakeup() returns false for given device.

Make e100 use pci_pme_active(), which carries out exactly the
required operations, instead.

      e1000: prevent corruption of EEPROM/NVM · 78566fec
      由 Christopher Li 提交于 
      Andrey reports e1000 corruption, and that a patch in vmware's ESX fixed
it.

The EEPROM corruption is triggered by concurrent access of the EEPROM
read/write. Putting a lock around it solve the problem.

      forcedeth: call restore mac addr in nv_shutdown path · f55c21fd

|    [netdrvr] forcedeth: setup wake-on-lan before shutting down
|
|    When hibernating in 'shutdown' mode, after saving the image the suspend hook
|    is not called again.
|    However, if the device is in promiscous mode, wake-on-lan will not work.
|    This adds a shutdown hook to setup wake-on-lan before the final shutdown.

my servers with nvidia ck804 and mcp55 will reverse mac address with kexec.

it turns out that we need to restore the mac addr in nv_shutdown().

      bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned int · 27ed9ddf
      由 Benjamin Li 提交于 
      The bnx2 driver stores/uses the irq value from the pci_dev internally.
But when it stores the irq value, it has been performing an
integer demotion.  Because of the recent changes made to
arch/x86/kernel/io_apic.c, the new method in creating the irq value
(using build_irq_for_pci_dev()) has exposed this bug on x86 systems.

Because of this demotion when calling request_irq() from
bnx2_request_irq(), the driver would get a return code of -EINVAL.
This is because the kernel could not find the requested irq descriptor.
By storing the irq value properly, the kernel can find the correct
irq descriptor and the bnx2 driver can operate normally.

      sctp: Fix oops when INIT-ACK indicates that peer doesn't support AUTH · add52379
      由 Vlad Yasevich 提交于 
      If INIT-ACK is received with SupportedExtensions parameter which
indicates that the peer does not support AUTH, the packet will be
silently ignore, and sctp_process_init() do cleanup all of the
transports in the association.
When T1-Init timer is expires, OOPS happen while we try to choose
a different init transport.

The solution is to only clean up the non-active transports, i.e
the ones that the peer added.  However, that introduces a problem
with sctp_connectx(), because we don't mark the proper state for
the transports provided by the user.  So, we'll simply mark
user-provided transports as ACTIVE.  That will allow INIT
retransmissions to work properly in the sctp_connectx() context
and prevent the crash.

      由 Vlad Yasevich 提交于 
      Do not enable peer features like addip and auth, if they
are administratively disabled localy.  If the peer resports
that he supports something that we don't, neither end can
use it so enabling it is pointless.  This solves a problem
when talking to a peer that has auth and addip enabled while
we do not.  Found by Andrei Pelinescu-Onciul <andrei@iptel.org>.

      [XFS] Don't do I/O beyond eof when unreserving space · 2fd6f6ec
      由 Lachlan McIlroy 提交于 
      When unreserving space with boundaries that are not block aligned we round
up the start and round down the end boundaries and then use this function,
xfs_zero_remaining_bytes(), to zero the parts of the blocks that got
dropped during the rounding. The problem is we don't consider if these
blocks are beyond eof. Worse still is if we encounter delayed allocations
beyond eof we will try to use the magic delayed allocation block number as
a real block number. If the file size is ever extended to expose these
blocks then we'll go through xfs_zero_eof() to zero them anyway.
