tracing/syscalls: Fix perf syscall tracing when syscall_nr == -1

syscall_get_nr can return -1 in the case that the task is not executing
a system call.

This patch fixes perf_syscall_{enter,exit} to check that the syscall
number is valid before using it as an index into a bitmap.

tracing/syscalls: Ignore numbers outside NR_syscalls' range

ARM has some private syscalls (for example, set_tls(2)) which lie
outside the range of NR_syscalls.  If any of these are called while
syscall tracing is being performed, out-of-bounds array access will
occur in the ftrace and perf sys_{enter,exit} handlers.

 # trace-cmd record -e raw_syscalls:* true && trace-cmd report

Fix this by ignoring out-of-NR_syscalls-bounds syscall numbers.

Commit cd0980fc8add "tracing: Check invalid syscall nr while tracing syscalls"
added the check for less than zero, but it should have also checked
for greater than NR_syscalls.

usb: gadget: mass_storage: added sysfs entry for cdrom to LUNs

This patch adds a "cdrom" sysfs entry for each mass_storage LUN, just
like "ro" sysfs entry. This allows switching between USB and CD-ROM
emulation without reinserting the module or recompiling the kernel.

Previously, the extradata size was included within VENUS_BUFFER_SIZE

query directly instead of doing guesswork.

msm: vidc: Change in input buffer size calculation

Right now, input buffer size is calculated based on
maximum supported height and width returned from FW.
These values are not true representation as they are
calculated for rotation usecase. Driver needs to use
max MB supported from FW. This change fixes the same.

msm_serial_hs: Initialize tty_flush_recieve while Port Open

Initialize the tty_flush_recieve to default value during
Port Open to avoid a corner case where Tx bytes may get queued
twice by UART in the absence of initialization.

Corner Case:
UART client calls uart_flush_buffer() API to flush the
data on Tx while UART Tx is in middle of operation.
If client immediately calls UART Port close followed by UART Tx
after Port-Open, it may result in queueing same bytes twice
