When retrying a failed BIO_RW_BARRIER request, we need to keep the reference in ->nr_pending over the whole retry. Currently, we only hold the reference if the failed request is the *last* one to finish - which is silly, because it would normally be the first to finish. So move the rdev_dec_pending call up into the didn't-fail branch. As the rdev isn't used in the later code, calling rdev_dec_pending earlier doesn't hurt.

Move the test for 'do barrier work' down a bit so that if the first write to a raid1 is a BIO_RW_BARRIER write, the checking done by superblock writes will cause the right thing to happen.

A context switch will force a call to flush_tlb_pending() (via switch_to()), so if we test tlb_nr to be non-zero, then sleep, it would become zero and later back at the original context we'll pass zero down into the TLB flushing code which should never see a nr argument of zero.

Fix bug in nvram write function. If the starting nvram address offset happens to be the last dword of the page, the NVRAM_CMD_LAST bit will not get set in the existing code. This patch fixes the bug by changing the "else if" to "if" so that the last dword condition always gets checked. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

Add a reset_phy parameter to tg3_reset_hw() and tg3_init_hw(). With the full chip reset during MAC address change, the automatic PHY reset during chip reset will cause a link down and bonding will not work properly as a result. With this reset_phy parameter, we can do a chip reset without link down when changing MAC address or MTU.

We eliminated rt6_dflt_lock (to protect default router pointer) at 2.6.17-rc1, and introduced rt6_select() for general router selection. The function is called in the context of rt6_lock read-lock held, but this means, we have some race conditions when we do round-robin.

I was looking through the xfrm input/output code in order to abstract out the address family specific encapsulation/decapsulation code. During that process I found this bug in the IP ID selection code in xfrm4_output.c. At that point dst is still the xfrm_dst for the current SA which represents an internal flow as far as the IPsec tunnel is concerned. Since the IP ID is going to sit on the outside of the encapsulated packet, we obviously want the external flow which is just dst->child.

This patch disables and saves local interrupts during hash_page processing for SPE contexts. We have to do it explicitly in the spu_irq_class_1_bottom function.
