commit 98dd166e upstream. With commit 633d6f17 (x86/xen: prepare p2m list for memory hotplug) the P2M may be sized to accomdate a much larger amount of memory than the domain currently has. When saving a domain, the toolstack must scan all the P2M looking for populated pages. This results in a performance regression due to the unnecessary scanning. Instead of reporting (via shared_info) the maximum possible size of the P2M, hint at the last PFN which might be populated. This hint is increased as new leaves are added to the P2M (in the expectation that they will be used for populated entries). Signed-off-by:

commit 370f06c8 upstream. Commit 7a786832 ("powerpc/perf: Add an explict flag indicating presence of SLOT field") introduced the PPMU_HAS_SSLOT flag to remove the assumption that MMCRA[SLOT] was present when PPMU_ALT_SIPR was not set. That commit's changelog also mentions that Power8 does not support MMCRA[SLOT]. However when the Power8 PMU support was merged, it errnoeously included the PPMU_HAS_SSLOT flag. So remove PPMU_HAS_SSLOT from the Power8 flags. mpe: On systems where MMCRA[SLOT] exists, the field occupies bits 37:39 (IBM numbering). On Power8 bit 37 is reserved, and 38:39 overlap with the high bits of the Threshold Event Counter Mantissa. I am not aware of any published events which use the threshold counting mechanism, which would cause the mantissa bits to be set. So in practice this bug is unlikely to trigger.

commit 6c55d9b9 upstream. Some recent (early 2015) macbooks have Intel Broadwell where LPSS UARTs are PCI enumerated instead of ACPI. The LPSS UART block is pretty much same as used on Intel Baytrail so we can reuse the existing Baytrail setup code. Add both Broadwell LPSS UART ports to the list of supported devices. Signed-off-by:

commit 74256377 upstream. There are a couple of nasty truncation bugs lurking in the pageattr code that can be triggered when mapping EFI regions, e.g. when we pass a cpa->pgd pointer. Because cpa->numpages is a 32-bit value, shifting left by PAGE_SHIFT will truncate the resultant address to 32-bits. Viorel-Cătălin managed to trigger this bug on his Dell machine that provides a ~5GB EFI region which requires 1236992 pages to be mapped. When calling populate_pud() the end of the region gets calculated incorrectly in the following buggy expression, end = start + (cpa->numpages << PAGE_SHIFT); And only 188416 pages are mapped. Next, populate_pud() gets invoked for a second time because of the loop in __change_page_attr_set_clr(), only this time no pages get mapped because shifting the remaining number of pages (1048576) by PAGE_SHIFT is zero. At which point the loop in __change_page_attr_set_clr() spins forever because we fail to map progress. Hitting this bug depends very much on the virtual address we pick to map the large region at and how many pages we map on the initial run through the loop. This explains why this issue was only recently hit with the introduction of commit a5caa209 ("x86/efi: Fix boot crash by mapping EFI memmap entries bottom-up at runtime, instead of top-down") It's interesting to note that safe uses of cpa->numpages do exist in the pageattr code. If instead of shifting ->numpages we multiply by PAGE_SIZE, no truncation occurs because PAGE_SIZE is a UL value, and so the result is unsigned long. To avoid surprises when users try to convert very large cpa->numpages values to addresses, change the data type from 'int' to 'unsigned long', thereby making it suitable for shifting by PAGE_SHIFT without any type casting. The alternative would be to make liberal use of casting, but that is far more likely to cause problems in the future when someone adds more code and fails to cast properly; this bug was difficult enough to track down in the first place.

Commit f79b0d9c ("staging: speakup: Fixed warning <linux/serial.h> instead of <asm/serial.h>") broke the port information in the speakup driver: SERIAL_PORT_DFNS only gets defined if asm/serial.h is included, and no other header includes asm/serial.h.

commit 7ee96216 upstream. ALSA dummy driver can switch the timer backend between system timer and hrtimer via its hrtimer module option. This can be also switched dynamically via sysfs, but it may lead to a memory corruption when switching is done while a PCM stream is running; the stream instance for the newly switched timer method tries to access the memory that was allocated by another timer method although the sizes differ. As the simplest fix, this patch just disables the switch via sysfs by dropping the writable bit.

commit 6d27a63c upstream. Although n_tty_check_unthrottle() has a valid ldisc reference (since the tty core gets the ldisc ref in tty_read() before calling the line discipline read() method), it does not have a valid ldisc reference to the "other" pty of a pty pair.

commit 5c17c861 upstream. ioctl(TIOCGETD) retrieves the line discipline id directly from the ldisc because the line discipline id (c_line) in termios is untrustworthy; userspace may have set termios via ioctl(TCSETS*) without actually changing the line discipline via ioctl(TIOCSETD). However, directly accessing the current ldisc via tty->ldisc is unsafe; the ldisc ptr dereferenced may be stale if the line discipline is changing via ioctl(TIOCSETD) or hangup. Wait for the line discipline reference (just like read() or write()) to retrieve the "current" line discipline id. Signed-off-by:

commit 13b43891 upstream. Runtime suspend during driver probe and removal can cause problems. The driver's runtime_suspend or runtime_resume callbacks may invoked before the driver has finished binding to the device or after the driver has unbound from the device. This problem shows up with the sd and sr drivers, and can cause disk or CD/DVD drives to become unusable as a result. The fix is simple. The drivers store a pointer to the scsi_disk or scsi_cd structure as their private device data when probing is finished, so we simply have to be sure to clear the private data during removal and test it during runtime suspend/resume.

commit 5a4ff9ec upstream. TEAC UD-501/UD-503/NT-503 fail to switch properly between different rate/format. Similar to 'Playback Design', this patch corrects the invalid clock source error for TEAC products and avoids complete freeze of the usb interface of 503 series. Signed-off-by:

commit 462b3f16 upstream. Some architectures like PowerPC can handle the maximum struct size in an ioctl only up to 13 bits, and struct snd_compr_codec_caps used by SNDRV_COMPRESS_GET_CODEC_CAPS ioctl overflows this limit. This problem was revealed recently by a powerpc change, as it's now treated as a fatal build error. This patch is a stop-gap for that: for architectures with less than 14 bit ioctl struct size, get rid of the handling of the relevant ioctl. We should provide an alternative equivalent ioctl code later, but for now just paper over it. Luckily, the compress API hasn't been used on such architectures, so the impact must be effectively zero.

commit 4152b387 upstream. In certain kernel configurations where the cdc_ether and option drivers are compiled as modules there can occur a race condition in enumeration. This causes the option driver to enumerate the ethernet(wwan) interface as usb-serial interfaces. usb-devices output for the modem: T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 5 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=1e2d ProdID=0055 Rev=00.00 S: Manufacturer=Cinterion S: Product=AHx C: #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=10mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

commit f436b2ac upstream. The Performance Monitors extension is an optional feature of the AArch64 architecture, therefore, in order to access Performance Monitors registers safely, the kernel should detect the architected PMU unit presence through the ID_AA64DFR0_EL1 register PMUVer field before accessing them. This patch implements a guard by reading the ID_AA64DFR0_EL1 register PMUVer field to detect the architected PMU presence and prevent accessing PMU system registers if the Performance Monitors extension is not implemented in the core.

commit da10816e upstream. ALSA OSS sequencer spews a kernel error message ("ALSA: seq_oss: too many applications") when user-space tries to open more than the limit. This means that it can easily fill the log buffer. Since it's merely a normal error, it's safe to suppress it via pr_debug() instead. Signed-off-by:

commit 59915133 upstream. ALSA sequencer OSS emulation code has a sanity check for currently opened devices, but there is a thinko there, eventually it spews warnings and skips the operation wrongly like: WARNING: CPU: 1 PID: 7573 at sound/core/seq/oss/seq_oss_synth.c:311 Fix this off-by-one error.

commit cac9b50b upstream. Fix null-pointer dereference at probe should a (malicious) Treo device lack the expected endpoints. Specifically, the Treo port-setup hack was dereferencing the bulk-in and interrupt-in urbs without first making sure they had been allocated by core.
