It is getting too big after the interrupt remaping entries debug print out was added. Original print_IO_APIC() becomes print_IO_APICs(). New print_IO_APIC() will only print one ioapic's registers As a side-effect this clean-up also made checkpatch.pl happier.

While checking irte dump in dmesg, the print out is confusing ioapic index with real io apic id: IOAPIC[0]: Set routing entry (1-1 -> 0x31 -> IRQ 1 Mode:0 Active:0 Dest:1) IOAPIC[1]: Set IRTE entry (P:1 FPD:0 Dst_Mode:1 Redir_hint:1 Trig_Mode:0 Dlvry_Mode:1 Avail:0 Vector:31 Dest:00000001 SID:00FF SQ:0 SVT:1) IOAPIC[0]: Set routing entry (1-2 -> 0x30 -> IRQ 0 Mode:0 Active:0 Dest:1) IOAPIC[1]: Set IRTE entry (P:1 FPD:0 Dst_Mode:1 Redir_hint:1 Trig_Mode:0 Dlvry_Mode:1 Avail:0 Vector:30 Dest:00000001 SID:00FF SQ:0 SVT:1) The system's first ioapic id is 1.

Ingo pointed out that setup_ioapic_entry() is way too big now. Split the intr-remap code out into setup_ir_ioapic_entry(). Also pass struct io_apic_irq_attr * instead of 5 parameters in those two functions. At last in setup_ir_ioapic_entry() we don't need to panic.

That flag no longer makes sense, since we don't look up automount points as eagerly any more. Additionally, it turns out that the NO_AUTOMOUNT handling was buggy to begin with: it would avoid automounting even for cases where we really *needed* to do the automount handling, and could return ENOENT for autofs entries that hadn't been instantiated yet. With our new non-eager automount semantics, one discussion has been about adding a AT_AUTOMOUNT flag to vfs_fstatat (and thus the newfstatat() and fstatat64() system calls), but it's probably not worth it: you can always force at least directory automounting by simply adding the final '/' to the filename, which works for *all* of the stat family system calls, old and new. So AT_NO_AUTOMOUNT (and thus LOOKUP_NO_AUTOMOUNT) really were just a result of our bad default behavior.

Currently the the internal oscillator is powered down when entering BIAS_OFF state, but not re-enabled when going back to BIAS_STANDBY. As a result the CODEC will stop working after suspend if the internal oscillator is used to generate the sysclock signal. This patch fixes it by clearing the appropriate bit in the power down register when the CODEC is re-enabled.

The concensus seems to be that system calls such as stat() etc should not trigger an automount. Neither should the l* versions. This patch therefore adds a LOOKUP_AUTOMOUNT flag to tag those lookups that _should_ trigger an automount on the last path element. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com> [ Edited to leave out the cases that are already covered by LOOKUP_OPEN, LOOKUP_DIRECTORY and LOOKUP_CREATE - all of which also fundamentally force automounting for their own reasons - Linus ] Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

由 Linus Torvalds 提交于
Since we've now turned around and made LOOKUP_FOLLOW *not* force an automount, we want to add the ability to force an automount event on lookup even if we don't happen to have one of the other flags that force it implicitly (LOOKUP_OPEN, LOOKUP_DIRECTORY, LOOKUP_PARENT..) Most cases will never want to use this, since you'd normally want to delay automounting as long as possible, which usually implies LOOKUP_OPEN (when we open a file or directory, we really cannot avoid the automount any more). But Trond argued sufficiently forcefully that at a minimum bind mounting a file and quotactl will want to force the automount lookup. Some other cases (like nfs_follow_remote_path()) could use it too, although LOOKUP_DIRECTORY would work there as well. This commit just adds the flag and logic, no users yet, though. It also doesn't actually touch the LOOKUP_NO_AUTOMOUNT flag that is related, and was made irrelevant by the same change that made us not follow on LOOKUP_FOLLOW.

Commit b7ab83ed (PM: Use spinlock instead of mutex in clock management functions) introduced a regression causing clocks_mutex to be acquired under a spinlock. This happens because pm_clk_suspend() and pm_clk_resume() call pm_clk_acquire() under pcd->lock, but pm_clk_acquire() executes clk_get() which causes clocks_mutex to be acquired. Similarly, __pm_clk_remove(), executed under pcd->lock, calls clk_put(), which also causes clocks_mutex to be acquired. To fix those problems make pm_clk_add() call pm_clk_acquire(), so that pm_clk_suspend() and pm_clk_resume() don't have to do that. Change pm_clk_remove() and pm_clk_destroy() to separate modifications of the pcd->clock_list list from the actual removal of PM clock entry objects done by __pm_clk_remove().

The spec->autocfg.line_out_pins[] may contain the same pins as hp_pins[] depending on the configuration. When they are identical, detecting the line_jack_present flag screws up the auto-mute because alc_line_automute() is called unconditionally at initialization while it won't be triggered by unsol events, thus the old line_jack_present flag is kept for the whole run. For fixing this buggy behavior, the driver needs to check whether the line-outs are really individual, and skip if same as headphone jacks.
