2011-01-21ath9k: add missing ps wakeup/restore callsFelix Fietkau2-5/+5
There are several places where ath_reset() was called without proper calls to ath9k_ps_wakeup/ath9k_ps_restore. To fix this, add those calls directly to ath_reset and drop them from callers where it makes sense. Also add them to the config callback around ath_update_txpow to fix a crash that happens when the tx power changed before any vif is brought up.

2011-01-21ath9k_hw: disabled PAPRD for AR9003Luis R. Rodriguez2-1/+6
AR9003's PAPRD was enabled prematurely, and is causing some large discrepancies on throughput and network connectivity. For example downlink (RX) throughput against an AR9280 AP can vary widlely from 43-73 Mbit/s while disabling this gets AR9382 (2x2) up to around 93 Mbit/s in a 2.4 GHz HT20 setup.

2011-01-21perf symbols: Fix annotation of thumb codeDr. David Alan Gilbert1-0/+7
In ARM's Thumb mode the bottom bit of the symbol address is set to mark the function as Thumb; the instructions are in reality 2 or 4 byte on 2 byte alignments, and when the +1 address is used in annotate it causes objdump to disassemble invalid instructions. The patch removes that bottom bit during symbol loading. Many thinks to Dave Martin for comments on an initial version of the patch.

2011-01-21RTC: Properly handle rtc_read_alarm error propagation and fix bugJohn Stultz1-3/+9
In reviewing cases where the virtualized interfaces didn't propagate errors properly, I noticed rtc_read_alarm needed fixing. In doing so I noticed my RTC rework dropped a memset and that the behavior of rtc_read_alarm shouldn't be conditionalized on the alarm.enabled flag (as the alarm may be set, but the irqs may be disabled). So those were corrected as well.

2011-01-21RTC: Propagate error handling via rtc_timer_enqueue properlyJohn Stultz2-23/+28
In cases where RTC hardware does not support alarms, the virtualized RTC interfaces did not have a way to propagate the error up to userland. This patch extends rtc_timer_enqueue so it catches errors from the hardware and returns them upwards to the virtualized interfaces. To simplify error handling, it also internalizes the management of the timer->enabled bit into rtc_timer_enqueue and rtc_timer_remove. Also makes rtc_timer_enqueue and rtc_timer_remove static.

2011-01-21xen: p2m: correctly initialize partial p2m leafStefan Bader1-1/+19
After changing the p2m mapping to a tree by commit 58e05027b530ff081ecea68e38de8d59db8f87e0 xen: convert p2m to a 3 level tree and trying to boot a DomU with 615MB of memory, the following crash was observed in the dump: kernel direct mapping tables up to 26f00000 @ 1ec4000-1fff000 BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<c0107397>] xen_set_pte+0x27/0x60 *pdpt = 0000000000000000 *pde = 0000000000000000 Adding further debug statements showed that when trying to set up pfn=0x26700 the returned mapping was invalid. pfn=0x266ff calling set_pte(0xc1fe77f8, 0x6b3003) pfn=0x26700 calling set_pte(0xc1fe7800, 0x3) Although the last_pfn obtained from the startup info is 0x26700, which should in turn not be hit, the additional 8MB which are added as extra memory normally seem to be ok. This lead to looking into the initial p2m tree construction, which uses the smaller value and assuming that there is other code handling the extra memory. When the p2m tree is set up, the leaves are directly pointed to the array which the domain builder set up. But if the mapping is not on a boundary that fits into one p2m page, this will result in the last leaf being only partially valid. And as the invalid entries are not initialized in that case, things go badly wrong. I am trying to fix that by checking whether the current leaf is a complete map and if not, allocate a completely new page and copy only the valid pointers there. This may not be the most efficient or elegant solution, but at least it seems to allow me booting DomUs with memory assignments all over the range.
