2018-08-22h8300: fix IRQ noYoshinori Sato1-1/+1

2018-08-22arch/h8300: add a defconfig targetRandy Dunlap1-0/+2
Make the "defconfig" target valid for arch/h8300. Currently "make ARCH=h8300 defconfig" produces: *** Can't find default configuration "arch/h8300/defconfig"! ../scripts/kconfig/Makefile:87: recipe for target 'defconfig' failed By adding a value for KBUILD_DEFCONFIG, "make ARCH=h8300 defconfig" successfully produces a kernel .config file: *** Default configuration is based on 'edosk2674_defconfig' This is useful for Kconfig editing/testing.

2018-08-22h8300:let the checker know that size_t is ulongLuc Van Oostenryck1-0/+2
All 64bit archs use unsigned long for size_t and most 32bit archs use 'unsigned int'. By default, this is what is assumed by sparse. However, on h8300 (a 32bit arch) size_t is unsigned long which can led sparse to emit wrong warnings. Fix this by passing to sparse the flag -msize-long, telling it that size_t is unsigned long.

linux/kernel.h isn't needed by asm/atomic.h and will result in circular dependencies when the asm-generic atomic bitops are built around the tomic_long_t interface.

2018-08-22h8300: remove unnecessary of_platform_populate callRob Herring1-10/+0
The DT core will call of_platform_populate, so it is not necessary for arch specific code to call it unless there are custom match entries, auxdata or parent device. Neither of those apply here, so remove the call.

2018-08-22h8300: switch to NO_BOOTMEMRob Herring2-28/+9
Commit 0fa1c579349f ("of/fdt: use memblock_virt_alloc for early alloc") inadvertently switched the DT unflattening allocations from memblock to bootmem which doesn't work because the unflattening happens before bootmem is initialized. Swapping the order of bootmem init and unflattening could also fix this, but removing bootmem is desired. So enable NO_BOOTMEM on h8300 like other architectures have done.

2018-08-21target/iscsi: Allocate session IDs from an IDAMatthew Wilcox3-30/+10

2018-08-21iscsi target: fix session creation failure handlingMike Christie1-14/+21
The problem is that iscsi_login_zero_tsih_s1 sets conn->sess early in iscsi_login_set_conn_values. If the function fails later like when we alloc the idr it does kfree(sess) and leaves the conn->sess pointer set. iscsi_login_zero_tsih_s1 then returns -Exyz and we then call iscsi_target_login_sess_out and access the freed memory. This patch has iscsi_login_zero_tsih_s1 either completely setup the session or completely tear it down, so later in iscsi_target_login_sess_out we can just check for it being set to the connection.

2018-08-21ida: Add new APIMatthew Wilcox2-42/+87
Add ida_alloc(), ida_alloc_min(), ida_alloc_max(), ida_alloc_range() and ida_free(). The ida_alloc_max() and ida_alloc_range() functions differ from ida_simple_get() in that they take an inclusive 'max' parameter instead of an exclusive 'end' parameter. Callers are about evenly split whether they'd like inclusive or exclusive parameters and 'max' is easier to document than 'end'. Change the IDA allocation to first attempt to allocate a bit using existing memory, and only allocate memory afterwards. Also change the behaviour of 'min' > INT_MAX from being a BUG() to returning -ENOSPC. Leave compatibility wrappers in place for ida_simple_get() and ida_simple_remove() to avoid changing all callers. Signed-off-by: Matthew Wilcox <[email protected]>
2018-08-21ida: Lock the IDA in ida_destroyMatthew Wilcox1-6/+11
The user has no need to handle locking between ida_simple_get() and ida_simple_remove().
