r3480 added this check to account for the entry vector 0xfff00100 to be available for CPUs that need it. Today however, the NIP is not yet initialized at this point (zero), so the check always triggers. Moreover, BIOS size check is already done previously, so this part can be removed too.

2011-01-29mc146818rtc: update registers after a format changeAurelien Jarno
For some unknown reason, the MIPS kernel briefly changes the RTC to binary mode during boot, switch back to BCD mode and read the time. As the registers are updated only every second, they may still be in the old format when they are read. This patch forces a register update immediately after a format change (BCD/binary or 12/24H). This avoid long fsck during boot due to time wrap. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-29escc: fix interrupt flagsAurelien Jarno
Recent PowerPC kernel end up in kernel panic during boot in -nographic mode. In this mode the second serial port is used as the udbg console, and thus a few characters are sent on this port. This activates the tx interrupt flag, and later choke the Linux kernel, as it was not expecting such a flag to be set. The problem here comes from the fact that contrary to most devices the interrupt flags are only set if the interrupt is enabled. Quoting the datasheet: "If the corresponding IE bit is not set, the IP for that source of interrupt will never be set." This patch fixes that by enabling the interrupt flag only when the corresponding interrupt is enabled. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-25pulseaudio: process 1/4 buffer max at onceGerd Hoffmann
Limit the size of data pieces processed by the pulseaudio worker threads. Never ever process more than 1/4 of the buffer at once. Background: The buffer area currently processed by the pulseaudio thread is blocked, i.e. the main thread (or iothread) can't fill in more data there. The buffer processing time is roughly real-time due to the pa_simple_write() call blocking when the output queue to the pulse server is full. Thus processing big chunks at once means blocking a large part of the buffer for a long time. This brings high latency and can lead to dropouts. When processing the buffer in smaller chunks the rpos handling becomes a problem though. The thread reads hw->rpos without knowing whenever qpa_run_out has already seen the last (small) chunk processed and updated rpos accordingly. There is no point in reading hw->rpos though, pa->rpos can be used instead. We just need to take care to initialize pa->rpos before kicking the thread.

2011-01-24usb-msd: Propagate removable bit to SCSI deviceStefan Hajnoczi
USB Mass Storage Devices sometimes have the RMB (removable) bit set in the SCSI INQUIRY response. Thumbdrives tend to have the bit set whereas hard disks do not. Operating systems differentiate between removable devices and fixed devices. Under Linux, the anaconda installer looks for removable devices. Under Windows, only fixed devices may have more than one partition and AutoRun is also affected by the removable bit. For these reasons, allow USB Mass Storage Devices to override the removable bit: qemu -usb -drive if=none,file=test.img,cache=none,id=disk0 -device usb-storage,drive=disk0,removable=on The default is off.
